I have mananged to connect to a Quantum PLC via Modbus using Modsoft on a Windows XP laptop.
Whenever I try to view the status online I get the following error:
984 - Not logged in or a user is logged in on another port. Modbus Error Code 169
What does this error mean and how can I avoid it in the future?
Many thanks.
