Protocol
Modbus TCP
Modbus Address
Default value is 0x01
Changeable via Web Interface
Modbus TCP to RTU Gateway Functionality
Modbus TCP packages with different addresses (Different than device own address) converted to Modbus RTU and sent to Serial interface and serial packages received are sent to Ethernet side after converting to Modbus TCP
Save Output Values Before Auto Restart
Default enabled and when system auto restarts the values are saved and applied after restart
Changeable via Web Interface
Save Output Values and Apply on Power Up
Default disabled, user can activate and enter parameters for each output individually
Changeable via Web Interface
I/O Mirror Functionality
Default disabled
If enabled, device can read input value of remote HUR device and duplicate those values as output
