4.5 Data Updates

Revised October-2019
IEC 62591 Wireless Interface Instruction Manual (for ControlWave Micro)
If you notice that data updates for process variables are slow, this can
occur if the IEC 62591 device cannot process a data request fast enough.
If this happens it generates a delayed response message, and the RTU
re-requests the data.
To see if you are receiving delayed response messages, look for a 9
(Delayed Response Received) status on the ousDevCommishStatus
parameter of the Commission List entry.
