Title: System.ObjectDisposedException:
Post by: mourazo on May 21, 2020, 07:50:14 AM

Hello, I trying to change the IPAddress from the modbusTCPCom in execution time when I receive this exception

System.ObjectDisposedException: 'The discarded object cannot be accessed.
Name of the object "ModbusTCPDataLinkLayer'

What could be the problem?

Thanks.

It looks like changing the IP address causes the DLL to be disposed. Before changing the address, try disabling subscriptions:

ModbusTCPCom1.DisableSubscriptions=True
ModbusTCPCom1.IPAddress= "192.160.1.1"
ModbusTCPCom1.DisableSubscriptions=False
