Next values can be seen in same manner.
When selected as "Parsed Data as Modbus Frame", HUR will share data as follows
Device Name, Device Model, NTP Time and Data itself in hexadecimal format just like a Modbus query response. First byte will show data bytes count and rest is the data itself. Data will be in similar format with how the device responds when read via Modbus commands.
Here is an example for "Digital Out"
01 in beginning is hexadecimal equivalent for 1 byte data count
Next is the value of 8 ports which is "C3"
Binary equivalent of hec C3 is "11000011"
This means
Port 1 value is "1"
Port 2 value is "1"
Port 3 value is "0"
Port 4 value is "0"
Port 5 value is "0"
Port 6 value is "0"
Port 7 value is "1"
Port 8 value is "1"
The 1st bit is port 1 value and 8th bit is port 8 value.
Here is an example for "Digital In"
01 in beginning is hexadecimal equivalent for 1 byte data count
Next is the value of 8 ports which is "01"
Binary equivalent of hec C3 is "00000001"
This means
Port 1 value is "1"
Port 2 value is "0"
Port 3 value is "0"
Port 4 value is "0"
Port 5 value is "0"
Port 6 value is "0"
Port 7 value is "0"
Port 8 value is "0"
The 1st bit is port 1 value and 8th bit is port 8 value.
Here is an example for "Analog Out"
0A in beginning is hexadecimal equivalent for 10 bytes data count. Each value is 2 bytes, for 5 ports Analog out device, there are 10 bytes.
Next 2 bytes are the value of port 1 which is "01F4"
That means "500" in decimal and that is equal to "12.0mA" in a range of 0-1000.
Next values can be seen in same manner.
Here is an example for "Analog In"
10 in beginning is hexadecimal equivalent for 10 bytes data count. Each value is 2 bytes, for 8 ports Analog in device, there are 16 bytes.
Next 2 bytes are the value of port 1 which is "7FBE"
That means "32702" in decimal and that is equal to "9.98mA" in range 0-65535.
Next values can be seen in same manner.
NOTE: Analog Out and Digital Out models can also be controlled via MQTT server.
Format will be as follows:
IO11:500
Letters 'I' and 'O', then Slot number '1' (always 1 for single Slot devices and can be 1-2-3-4 for multi slot device), then ':' and then the value which is a value between range 0-1000 for Analog output version and 0 or 1 for Digital out version. User can write multiple commands and those must be seperated with new line '\n' or 0x0D in hexadecimal format.
Here is screenshot for an example:
When all settings are done click "Save Configuration".
Go back to "https://tago.io/" panel and click "Live Inspector" for the HUR 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 HUR usage.
NOTE: HUR Multi models send values to MQTT server for all slots. HUR single slot versions can also send values for 1 slot.
HUR single slot or multi slot Output slots can be managed from MQTT server in same manner.
HUR Series Modbus TCP Remote I/O Devices Output versions can duplicate input value of Input versions. Outputs can be 5-275V AC-DC, 100mA Digital Optocoupler Output or 5Amperes 250VAC/30VDC Relay Output or 4-20mA Analog Output. Following devices can be used as output device for this application:
HUR158 and HUR258 with 8 Channel 5-275V AC-DC, 100mA Digital Optocoupler Output
HUR168 and HUR268 with 8 Channel Digital 5Amps 250VAC/30VDC Relay Output
Inputs can be 12-275V AC-DC, 60mA Digital Optocoupler Input or 4-20mA Analog Input. Following devices can be used for this application:
As expected, Analog devices can pair with each other and Digital devices can pair with each other.
NOTE: I/O Mirror Application can be done between same I/O devices which means Analog devices can pair with each other and Digital devices can pair with each other.
Here is an example video for I/O Mirror application between
The Analog Current value we input from Analog In HUR is set to Analog Out HUR via TLM Series LoRa RF Modems.
Here is the video for configurations:
HUR Series Modbus TCP Remote I/O Devices lets user to read input values or write output values over Modbus TCP. Simultaneously all meter data can be sent to MQTT Server. Analog Out and Digital Out slots can also be controlled via MQTT server.
All read data can be sent to MQTT server for web based applications. Also MQTT Server can control field device remotely via commands. Field device can read/write HUR Series Modbus TCP Remote I/O Devices, all can take place in simultaneously.
In this application, following model is used:
