TurboDurbin

This seems like a good solution. In the past we have used the heartbeat to determine the state but like you said this isn't truly program mode, it could be faulted. The Proface unit is pretty good talking with the Logix 5000, it takes a direct import of the .L5K file and uses that as the tags in the GDU. This issue is not imparative I was just hoping that we could come up with something, the output is probably the best solution I will let you know what I end up doing, it may be one of those things that I don't worry about because it is on a screen that no one besides me will probably look at. Plus most people just open the cabinet to look at the PLC instead of using the screens that I have spent hours developing.

1756-L61 PLC with a XYCOM/PROFACE AGP-3600T GDU. So you are saying it is a status bit that can always be read? If that is the case I should be able to just use the GDU to look at that/those bits. Let me know if you have some more exact info since I gave you some more exact info.

I was wondering if anyone can think of a solution to displaying the "keyswitch" in program mode on a GDU. The logic is all there the problem is that the PLC isn't scanning the logic in program mode. Any clever solutions?

You were correct: To discover the ControlNet Mac Id use the following message: Service: 0x0E (Get_Attribute_Single) Class: 0xF0 (ControlNet Object) Instance: 0x01 Attribute: 0x84 (MAC_ID) The data returned by the module will be 4 bytes conforming to the following structure: MAC_ID_current USINT MAC_ID_switches USINT MAC_ID_changed BOOL Reserved USINT I didn't know MAC ID was teh same as CNET Node #

Thanks for the info finally got to the article. Too bad the .bmp is no good and I can't acctually see the settings I need to use. Oh well I give up.

I called tech support and they gave me that same TN# 19053 which I found however I can not fins the 24538 that you referenced or the 25592 that they referenced when I was on the phone. Is there something I am doing wrong when searching the knowledgbease?

I need to be able to display the node number on the GDU because it will save me from having to change it on different gdu screens and projects. I used a MSG instruction to get the IP information from the ENBT card I just need to get the info from the CNB\E card. This is a 1756-ControlLogix Chassis. I think all I need to do is know the Class, Instance, and Attribute for the CIP Generic Message Type. Please help me if you could.
