KINCO PLC as MODBUS RTU slave

[Francisco1998 0]

Hello to everyone. I hope you are doing well.

I'm trying to establish a communication between my PC and my KINCO PLC. The manual states it supports MODBUS RTU protocol, so I downloaded two different Modbus Master simulator I found out: Multiway from OMRON and qModMaster. None of them seem to work properly. I attached some pictures of the messages I get.

I include the configuration of the communication parameters.

qModMaster parameters

According to the manual, in order to play the role of Modbus master with the PLC it's necessary to configure some instruction blocks (I'm programming in ladder). However, I could not find any block to configure as Modbus slave. I don't know what else I can do.

I'm in trouble with this task. Am I making some mistake?

Thanks for your attention. 
Kind regards!
