MB-700 – User’s Manual
4.8
4 - F_VALUE Parameter:
Through this parameter user will visualize float variables addressed by F_ADDRESS_i. The block
supports up to 16 float variables that can be mapped for supervision of the Modbus slave device.
C - Supervision Status
1 - SCAN_STATUS Parameter:
Status parameter of the scan done by the MB-700 in the communication with serial slave devices.
BIT Message Description
0 Last write message Failed
When the value set for NUMBER_RETRANSMISSIONS is reached,
and if the MB-700 didn’t get to write data properly, the value
SCAN_STATUS will indicate “Last write message Failed”.
1 Scan failed
When the value set on NUMBER_RETRANSMISSIONS is reached
and the MB-700 didn’t get an answer from the serial slave, the value
of SCAN_STATUS will indicate “Scan Failed’.
2 Using configurable view
If user set SCAN_BEHAVIOR equal to one and the communication
with the slave is done using View the scan status will indicate “Using
Configurable View”
3 Scan Stopped Indicates if the scan stopped for any reason.
