Can anyone provide suggestions on how to code PLCs and Lookout to wait for acknowledgements from each other or a reference to a discussion about this topic?
Please be more detailed.
Lookout polls PLC, PLC responds. Is that acknowledgment?
Lookout polls PLC, PLC responds, Lookout performs a specific action after PLC responds
and also the reverse...
PLC polls Lookout, Lookout responds, PLC waits until Lookout finishes responding.
There are a few different things I'd like to do:
1. Have Lookout PLC timers and counters with values from a DataTable. The PLC should wait until the DataTable is completely updated.
2. Have Lookout save to a data file. The PLC should wait until Lookout has completed saving the data.
