I am using RaspberryPI 3B as ModbusTCP slave device. Until now I was using Codesys Control fOR Raypberry version 3.5.14 and it was working OK. Now I have updated the Raspberry with Codesys Control 3.5.16 and Modbus is working very slow. Reading and writting into Modbus registers is very slow.
What could be the reason?
Best regards

Hello,
I have solved this.
Bus Cycle Task has to be set to "Task"
Always Update Variables has to be set to "Enabled 2 (always in bus cycle task)"
Now it is working with normal speed.
