I am configuring Modbus TCP for my device (I/O module)
- Set up a bridge with the device, online
- Configured the Poll bridge, online. The input registers start with 160. The number 160 was specified in the settings
- I configure Modbus Data, I specify read address 160
The values are not correct.
I change the read address to 161 and the value is correct, but from the second input, the offset is -1. At the same time, I cannot specify 159 for the first entry. If you specify the address of register 159 in the poll bridge, then the device is not online.
What needs to be done?
