The choking of the network was an extreme example from my past, not this application. Yes, what you mentioned about using 2 bethos inputs, then a value triggers a data store. However I was avoiding reading the 14,700 word block cyclical. The data block is populated over 10s at a resolution of the PLC task time, of 0.9ms. It’s not real time, it populates then is at rest until the next test.
