Hello,
We are using Beckhoff modules for the communication between the devices (mass flow controllers) and the siemens PLC. For the serial communication between the PLC and the mass flow controller we intend to use the Beckhoff serial interface module KL6021. The mass flow controller supports only the Modbus RTU protocol. For this purpose we would like to have more information as to how to configure the KL6021 and exchange the information between the mass flow controller and the PLC. The information for exchange may be greater than 6 bytes( the input/output image for the beckhoff and the siemens plcis 1byte control/status and 3 bytes data).
Please tell whether this can be done. And the method we have to implement for the Modbus protocol if needed or it is already implemented in the KL6021.
Thank You.
With best regards
