Modbus-TCP, ASCII protocol • VEGAMET 391/624/625, VEGASCAN 693, PLICSRADIO C62
30768-EN-130701
Status Measured
value
Meaning
<> 0 0 An error number is transmitted in the status
corresponding to the error codes Exx (e.g. 29
= E29 = Simulation).
<> 0 XX0XX An error number which corresponds to the er-
ror codes Exx is transmitted in the status and
in the measured value. Must be configured
via DTM.
The switching conditions of the relay are transferred as bit information.
The following equivalencies apply to the switching relays:
•
0 = Switching status Off
•
1 = Switching status On
The following equivalencies apply to the fail safe relay:
•
0 = Failure message Off, relay switching condition On
•
1 = Failure message Off, relay switching condition Off
The following chart shows the addressing of the temporary memory
