Modbus disconnection

Hi

I am using PLC Emulation with modbus. It works for the first run but fails to re-run. However if I re-start the model or reset the PLC, it works again for one round. It seems to me the modbus communication needs to be reset (close) before I re-run the model again. Is it a norm? Instead of the reset the PLC or restart the model in new FlexSim session, what is FlexScript can close the communication? Will clientclose or socketend works?

Regards

David

FlexSim team released 19.2.4 to close the modbus connection. However I have not tried since then. I will update you when I got my PLC in for the testing.

Have you tried it since 19.2.4?

This should be fixed now.
