1.2.9 Data Dropout Detection (GX/GP/GM)
The GX/GP/GM can detect GX70SM data acquisition dropouts caused by communication
errors or the like by collecting the GX70SM data serial numbers.* When the data serial
number received from the GX70SM does not change over a specified period, the GX/GP/
GM decides that a data dropout has occurred.
The occurrence of data dropouts can be output and recorded as alarms.
You can view the alarms that have occurred on the monitor view. Further, they can be used
to trigger internal switches, relay output, and e-mail transmission.
