Does anyone know of a way to monitor the number of consumers of a ControLogix produced tag?
I have an application with over 30 CNet nodes connected to a supervisory ControLogix processor (mixture of PLC-5's, ControLogix processors). The supervisor produces a tag that used for line control and synchronization and I would like to monitor the number of devices that consume this tag. I know what the value should be and want to verfiy that all nodes are receiving the tag. If the number of consumers is not equal to the expected value a stop is created and the process is stopped due to a CNet Comm Fault.
The supervisor was recently upgraded to ControLogix from a PLC-5. Before the update I could monitor the status words for the produced tag (message) to see how many devices were consuming the tag.
Now with the produced tag being created in RSLogix 5000, I do not have the option of monitoring the status words for the tag. I have been using a GSV to check the Entry Status for each of the devices, but recently one of the PLC-5 consumers was reloaded and the scheduled consumed message was not entered. For some reason the GSV did not catch the fact that the message was not being consumed. The device in question was unaware of the process starting and did not apply the required component.
