Hi,
As I wrote in the topic now I need some advice on how to check communication with modbus slave device.
Configuration what I have is below in the picture:
I searched tabs like in Modbus TCP where were Healthbits but in Serial probably it doesn't exist.
I try to use FB like IODrvModbusSerial where variable xAllSlavesOk shows FALSE and another variable uiNumberOfCommunicatingSlaves shows 0.
Maybe I using that FB wrong and that is why the variables show FALSE and 0.
