J_Bell Posts: 5822 Rating: (412)	I would like to know, do you see some change in the data valuesif you switch your PLC into Stop mode? Especially for the vfdstate()? Best regards J_Bell

J_Bell Posts: 5822 Rating: (412)	Dear BarP, the reason might be in your configuration. If you have a single sided configured Connection... this could be a reason. I tried it by myself right now the better choice for you would be the statepath() to check the Connection. To check the CPU I would choose to check the Clock Byte... but this only as an idea. Best regards J_Bell

J_Bell Posts: 5822 Rating: (412)	Dear BarP, a single sided connection is a Connection with a remote Partner that is unspecified. So the Remote TSAP is usually 03.02. But nevertheless I think that the use of vfdstate will not help you. Best regards J_Bell
