AC500 modbus slave address problem

Dear All,

please could someone help me with Modbus configuration of COM1 port on PM573 CPU? When I make a configuration with slave address 1 that seems to be working properly (checking with Modbus master simulator ModbusMAT or ModScan32). But when I change slave address to another one (for example 2) it stops working. Is there any additional setting I have to make to be able to use any one from address range?

Thanks!

Dear Radek,

You can make the communication with the slave address equal to 2 without any problems, maybe the software that simulates modbus communication does not work properly.
