I have a TECO SG2 that when a link to the controller all is fine. When I try to read the controller I get "Commands do not match SG2 edit mode" and the software will not display the logic. After research, it appears to be a communication error of some sort. Has anyone ever experienced this? How can it be resolved? I am very new to TECO so I am unfamiliar with the correct actions to take. ANY help would be GREAT! ! ! !
