Contrib S7 error

General

Hi! I'm working on a project using contrib s7, I have configured the PLC IP adress and Rack Slot and the memory adresses of some variables I am using in TIA Portal, everything was working fine for a while but I was working on it today and suddenly I get this error now: Error: PLC error [0x8104]: This service is not implemented on the module or a frame error was reported

The variable which is a boolean only shows as online and no true or false value as it was showing before, has anyone had a similar problem who can help me?

It generally helps to give the full package name so that it can be looked up. There are 2 pages of s7 related nodes on the flows site.
