STG Series WMBus Gateways can get Wireless MBus (WMBus) frames over air, Decrypt Up to 64 devices' WMBus packets, parse and map those parsed data to Modbus registers as well as send data to MQTT Server. STG has auto configuration feature to automatically list the received WMBus packages on configuration web interface for easy configuration.
STG has 6 Device Functions:
TCP/IP to WMBus Gateway: Receive WMBus frames and send to TCP IP client device connected to STG. STG can also send WMbus frames from TCP side to WMbus side (generation of frames).
WMBus - Modbus TCP Gateway (and MQTT Publisher): STG can get WMBus frames, decrypt, parse, convert to Modbus TCP (and send to MQTT).
WMBus Decoder/Parser and MQTT Publisher: STG can get WMBus frames, decrypt, parse and send to MQTT ( almost same like function 2 but no Modbus conversion functionality).
Serial to WMBus Gateway: Receive WMBus frames and send to Serial local device connected to STG over RS232 or RS485. STG can also send WMbus frames from serial side to WMbus side (generation of frames).
WMBus - Modbus RTU Gateway (and MQTT Publisher): STG can get WMBus frames, decrypt, parse, convert to Modbus RTU (and send to MQTT).
WMBus Repeater: STG can receive WMBus frames and send them again as WMBus messages to air. This is a repeater function.
In all function modes 1-2-3-4-5-6: STG can decrypt up to 64 devices' frames, for example in Function 6: Repeater function.
Typical applications: Automated Meter reading, Home – Building – Industrial Automation, Wireless Sensors, Telemetry…

Parsed data is shared by STG as data blocks as the details are given above. There are also 4 registers at the end of each frame (service registers) to show Access Number, RSSI value, Status value of frame and Decryption Status.
Here is an example Modbus data frame ( without Modbus frame header part and CRC part for Modbus RTU)
1A00144739269500420037000100000001000349D5DAE0002DFFCD
1A: 1 byte frame length, which is 1Ah and which is 26 in decimal and WMBus data shared as blocks
00144739: 4 bytes of WMBus device id
2695: 2 bytes of WMBus device manufacturer id
0042: 2 bytes of WMBus device version
0037: 2 bytes of WMBus device type
0001: 1 byte of Data count value. Data shared in blocks and this value shows how many blocks are there
00000001000349D5DAE0: Each data blocks has following values in 6 registers and 12 bytes
Storage Number (of data from meter) - 2 bytes
Function Field (of data from meter) - 2 bytes
Data Type (STG uses this value to identify type of Data that is shown above) - 2 bytes, Data Type is Volume in this example
Data Value (float data based on Data Type in this example) - 4 bytes, 1751900.0 in this example
002D: 1 byte of Access Number value as unsigned integer. 45 in this example.
FFCD: 1 byte of RSSI value as signed integer. -51 in this example.
STG series WMBus Gateways can get WMBus frames, decrypt the data and share data as Modbus values.
As a first step user should select "Device Function" under Operating Mode page:
"WMBus - Modbus TCP Gateway (and MQTT Publisher)" (available when device operation mode is server)
Or
"WMBus - Modbus RTU Gateway (and MQTT Publisher)" (available when device operation mode is client)
In this example we have selected "WMBus - Modbus TCP Gateway (and MQTT Publisher)" and saved configuration reboot device under "Management" menu.
"Modbus Scheduler Settings" is still empty in this stage.
STG will listen WMBus frames.
Click "Refresh Auto Config List" button under "WMBus Settings" menu. When this button clicked, STG will show received frames with latest RSSI values for all WMBus devices since the device powered up. If there is no RSSI value, that means STG did not receive any WMBus frame yet, user may wait and click button again.
If a line has notation "Recently Dedected" on the right side of entyr and framed with green line, that means this WMBus frame received and this device is not in configuration (or not in Black List), user may select it to "Add to Config" or "Add to Black List" based on needs.
If "Add to Black List" checked, after clicking "Save Configuration", STG will save this device id under "Black List Table" (and enables list by checking "Black List Enabled" checkbox, if not enabled already) under "Security Settings" menu. This entry also will be freed up from decryption list to be used for new coming frames.
NOTE: User must enter AES keys manually.
After all settings are done, click "Save Configuration" button. That process will save configuration and also put the device id to Modbus list ( and black List if it is used) automatically thus ease up configuration process dramatically.
Here is "Modbus Scheduler Settings" view under "Operating Mode" menu after saving settings.
Each WMBus device is separate MODBUS device so user should matched Manufacturing IDs of field devices with selected Modbus Device Addresses. Then user should enable the entry that STG will expect the WMBus data and share info as Modbus register.
Here is "Black List Address Table" view under "Security Settings" menu after saving settings.
NOTE: All values in "AES-128 Decryption List", "Modbus Scheduler Settings" and "Black List Address Table" can also be entered/changed mnaually. In that case user may get help from "WMBus Status" menu to get WMBus frame details as follows:
If WMbus – Modbus RTU Gateway is set, user can make serial interface settings under menu Serial Settings.
If WMbus – Modbus TCP Gateway is set, user can change Modbus TCP Port under menu Network Settings.
STG series WMbus – Modbus TCP/RTU Gateway devices can get WMBus OMS data and convert those to Modbus registers. Users or field devices can read WMBus data over Modbus registers. Here are basic rules:
- Each wMBUS device is separate MODBUS slave
Slave ID is possible to configure in STG web page "Operating Mode" in table "Modbus Scheduler Settings" column "Modbus address"
- MODBUS data is stored in three parts: Status Block, several Data Blocks depends of number measurements stored in WMBus device and finally the Service Block
Number of words needed to read all register is possible after counting length of data blocks. For example, if in status block "data count" value is equal to 2 you have to read 6+(2*5 (16))+4 words from address 0
- To restrict number of WMBUS devices it is possible use "White" or "Black" list of WMBus devices
See "Security Settings" in STG web configuration page
- To Decrypt WMBus devices you have to fill "AES-128 Decryption List"
See " WMBus Settings" in STG web configuration page
- Current WMBus frame details is possible to find in " WMBus Status" page
See " WMBus Status" in STG web configuration page
- Current Modbus frame details is possible to find in "Device Status" page
See "Device Status" in STG web configuration page
MODBUS data is stored in three parts: Status Block, several Data Blocks depends on number measurements stored in WMBus device and finally the Service Block.
Status Block, 6 Registers:
- WMbus Device ID: 2 Registers
- WMbus Man ID: 1 Register
- WMbus Version: 1 Register
- WMbus Type: 1 Register
- Total Data Count: 1 Register (Represents how many data blocks exists)
Data Block, each 5 Bytes total n bytes:
- Storage Number: 1 Register
- Function Field: 1 Register
- Data Type: 1 Register
- Data Value: 2 Registers
NOTE: Please check "Chapter 11: WMBus Data Parsing Format" to see details of Data Types used by STG
Service Block, 4 Registers:
- Access Number: 1 Register (comes from WMBus packet itself)
- RSSI Value: 1 Register
- Status (from Frame): 1 Register (comes from WMBus packet itself)
- Decrypt Status: 1 Register (status of packet after STG tries to decrypt)
In this example "Marcom OPC Server Modnet" software is used to read Modbus values and Modbus TCP protocol is used.
Any Modbus software can read following values with similar settings.
Enter TCP IP and TCP Port of STG for connection. In our example TCP IP is "192.168.0.121" and port is "502".
Then enter device Modbus ID.
In this example we want to read device id "0x00144739" and this is mapped with modbus address "5".
Then checked parsed data from "WMBus Status" page to see the parsed data. We will read 1 data blcok in this example.
NOTE: If data type part show "NOT IMPLEMENTED", data is not implemented as a valid type in STG and cannot be read via Modbus and that is not count in data blocks.
User may contact our company if that data is needed to be implemented and read via Modbus.
Enter register details and data types baesd on read data, in this example we will read Status Block, Data Block and Service Block (all blocks)
Status Block, 6 Registers:
- WMbus Device ID: 2 Registers, unsigned long
- WMbus Man ID: 1 Register, unsigned integer
- WMbus Version: 1 Register, unsigned integer
- WMbus Type: 1 Register, unsigned integer
- Total Data Count: 1 Register, unsigned integer
1 Data Block:
- Storage Number: 1 Register, unsigned integer
- Function Field: 1 Register, unsigned integer
- Data Type: 1 Register, unsigned integer
- Data Value: 2 Registers, Float 32 bytes
NOTE: Please check "Chapter 11: WMBus Data Parsing Format" to see details of Data Types used by STG.
In this example, "Data Type" is "VOLUME l".
Service Block, 4 Registers:
- Access Number: 1 Register (comes from WMBus packet itself)
- RSSI Value: 1 Register
- Status (from Frame): 1 Register (comes from WMBus packet itself)
- Decrypt Status: 1 Register (status of packet after STG tries to decrypt)
Save settings and click "Start OPC Server" (or F9) button to read values.
Here is log for sent and received frames
Received frame details are as follows:
00540000001D: 6 bytes of Modbus TCP protocol header
05: 1 byte of Modbus adress
03: 1 byte fo Modbus Function Code
1A: 1 byte data length, which is 1Ah and which is 26 in decimal and WMBus data shared as blocks
00144739: 4 bytes of WMBus device id

002D: 1 byte of Access Number value as unsigned integer. 45 in this example.
FFCD: 1 byte of RSSI value as signed integer. -51 in this example.
NOTE: This example is given for Modbus TCP Frame. Modbus RTU frame will be similar in following manner :
STG Series WMBus Gateways can get Wireless MBus (WMBus) frames, decrypt them and parse them. Field devices or applications can get meter WMBus data mapped to Modbus registers via Modbus TCP (or Modbsu RTU). Simultaneously all meter data can be sent to MQTT Server. STG has capability to decrypt and convert WMBus data to Modbus protocol as well as send data to MQTT Server for up to 64 devices in standard models (up to 20 WMBus devices in other models).
Enter meter reading details to STG and make sure all readings are ok.
Please follow details regarding settings and put into operation of STG based on explanations in "Chapter 12: WMBus OMS – Modbus Conversion Example" for adding WMBus meter details and parsing WMBus meter data.
Then go to "Network Settings" menu and "Enable MQTT Publisher for Parsed WMBus Packages" part.
In our example we will use "https://tago.io/" as MQTT Server.
Go to MQTT server panel and click "Add Device" to add STG to MQTT Server. We will also get password after adding device.
Select "Custom MQTT".
Then enter "Device name" in pop up screen and click "Create My Device".
Click "Finish" when all done.
Once the device is created, click "Copy Token" button. This will copy password value.
Then go back to STG and enter that value as password and click "Save Configuration" button.
"MQTT Broker IP": TCP IP of the MQTT Server. User must enter IP value
75.2.83.130 is IP of "https://tago.io/" web address.
"MQTT Broker Port": TCP Port of the MQTT Server.
1883 is TCP Port of "https://tago.io/" web address.
"Client ID": MQTT Publisher client id. Default is MQTT_STG_Client.
Maximum length for this field is 32.
"User Name": MQTT Publisher user name. This must be entered based on MQTT server settings.
Maximum length for this field is 64.
"Password": MQTT Publisher password. This must be entered based on MQTT server settings.
Maximum length for this field is 48.
"Publish Topic": MQTT Publisher topic value. Default is MQTT_STG_Publish_topic.
Maximum length for this field is 32.
"Subscribe Topic": MQTT Publisher subscribe topic value. Default is MQTT_STG_Subscribe_topic.
Maximum length for this field is 32.
"Minimum Send Interval for a Parsed Data (in seconds)": Minimum value to send meter data to MQTT Server. This time is the minimum time to send data to server, if WMBus meter sends frames in longer periods then it will be basis of the sending interval.
"Data Format": Options for how data is shared by STG with MQTT server. There are 2 options:
RAW WMBUS DECRYPTED DATA
PARSED DATA AS OBJECTS
PARSED DATA AS MODBUS FRAME
When selected as "Raw WMBus Decrypted Data", STG will share WMBus frame as it is but decrypted as follows as an example:
MQTT message shows STG device name, device id, NTP time and data itself
Data has values of WMBus Device Id, Manufacturer Id, Device Version, Device Type, RSSI Value of recevied signal, Access Number value and Decrypted frame Data Block.
When selected as "Parsed Data As Objects", STG will share WMBus data as parsed objects as follows as an example:
MQTT message shows STG device name, device id, NTP time and data itself
Data has values of WMBus Device Id, Manufacturer Id, Device Version, Device Type, RSSI Value of recevied signal, Access Number value.
Parsed Data is shared in blocks and Data Count value shows how many blocks are there.
In this example there is 1 block
{\"S\":\"0\",\"F\":\"1\",\"T\":\"3\",\"V\":\"1751900.0\"}
Here are explanations:
S: Storage Number (of data from meter)
F: Function Field (of data from meter)
T: Data Type (STG uses this value to identify type of Data)
V: Data Value (can be float or UINT - 4 byte data, matched with Data Type)
NOTE: Parsed data shared as data blocks. This is valid for both Modbus Frames and web page visualization. Each data block has following values:
- Data Type specified by STG
- Data Value (can be a float or long value)
- Function, available values are:
INSTANTANEOUS, MAXIMUM, MINIMUM or ERROR STATE
- Data Storage Number as an integer
details are explained in "Chapter 11: WMBus Data Parsing Format".
When selected as "Parsed Data As Modbus Frame", STG will share WMBus data as Modbus like frame as follows as an example:
MQTT message shows STG device name, device id, NTP time and data itself
Data has values of WMBus Device Id, Manufacturer Id, Device Version, Device Type, RSSI Value of recevied signal, Access Number value.
Parsed Data is shared in Modbus like frame, in this example as follows.
1A00144739269500420037000100000001000349D5DAE0002DFFCD
1A: 1 byte frame length, which is 1Ah and which is 26 in decimal and WMBus data shared as blocks
00144739: 4 bytes of WMBus device id
2695: 2 bytes of WMBus device manufacturer id
0042: 2 bytes of WMBus device version
0037: 2 bytes of WMBus device type
0001: 1 byte of Data count value. Data shared in blocks and this value shows how many blocks are there
00000001000349D5DAE0: Each data blocks has following values in 6 registers and 12 bytes
Storage Number (of data from meter) - 2 bytes
Function Field (of data from meter) - 2 bytes
Data Type (STG uses this value to identify type of Data that is shown in previous example) - 2 bytes, Data Type is Volume in this example
Data Value (float data based on Data Type in this example) - 4 bytes, 1751900.0 in this example
002D: 1 byte of Access Number value as unsigned integer. 45 in this example.
FFCD: 1 byte of RSSI value as signed integer. -51 in this example.
NOTE: Parsed data shared as data blocks. This is valid for both Modbus Frames and web page visualization. Each data block has following values:
- Data Type specified by STG
- Data Value (can be a float or long value)
- Function, available values are:
INSTANTANEOUS, MAXIMUM, MINIMUM or ERROR STATE
- Data Storage Number as an integer
details are explained in "Chapter 11: WMBus Data Parsing Format".
There are also 4 registers at the end of each frame (service registers) to show Access Number, RSSI value, Status value of frame and Decryption Status.
When all settings are done click "Save Configuration".
Go back to "https://tago.io/" panel and click "Live Inspector" for the STG and click "Play button".
Data will be shown in real time.
User has to parse and use that parsed data for visualization (for graphs for example) for their application. That is beyond scope of STG usage.
STG Series WMBus Gateways have built in mechanism to get WMBus frames and Auto Configure. AES Decryption, Modbus Adress mapping and Black list items can be auto filled by Auto Configuration mechanism, thus user do not have to enter manually each item besides AES Key. STG has capability to decrypt and convert WMBus data to Modbus protocol for up to 64 devices in standard models (up to 20 WMBus devices in other models and AES decryption is limited to 16 devices in D16 models).
STG Series WMBus Gateways can receive WMBus OMS packages and convert them to Modbus TCP packages. This way WMBus packages of up to 64 meters (Lite Models and D16 models support up to 20 WMBus devices) can directly be collected on a remote or local Data Server or RTU device as Modbus registers and can be used for other applications.
STG set in Server mode and Device function set as WMBus – Modbus TCP Gateway (and MQTT Publisher). Manufacturing IDs of field devices can be listed with related Modbus addresses. If needed decryption list can be set and White/Black list can be enabled. Received WMBus OMS messages will be converted to Modbus Registers and field or remote Modbus TCP devices can query that data from related Modbus addresses. The decrypted and parsed data can also be sent to MQTT Server in simultaneoulsy.
Here is an example video for this application (this video follows steps described in Chapter 12. WMBus OMS – Modbus Conversion Example) :
STG Series WMBus Gateways can receive WMBUS packages, decrypt data and parse. All parsed data can be sent to MQTT server for web based applications in several different formats. This way WMBus packages of up to 64 meters (Lite Models and D16 models support up to 20 WMBus devices) can directly be sent to a local or remote MQTT Server in one of predefined format and data can be analyzed and can be used for monitoring in server applications.
STG set in Server mode and Device function can be set as "WMBus Decoder/Parser and MQTT Publisher" or WMBus – Modbus TCP Gateway (and MQTT Publisher)".
Here is an example video for this application (this video follows steps described in Chapter 13. MQTT Communication Example) :
