4.14
D - Supervision Status
1 - Parameter COMM_STATUS
This parameter indicates if the communication between slaves was established properly. If the
corresponding bit is in logic level 1, it means there was an error during writing/reading of the
respective parameter.

Table 4.4 – Bit / Parameter Status
Parameter Status
Each input or output parameter has a corresponding status. The slave device through configuration
of the MODBUS_ADDRESS_OF_STATUS might update this status. This happens only if the slave
device has a status (this status follows the
F
OUNDATION
TM
Fieldbus standard). See more details of
how to set this status in the Function Blocks manual. If the MODBUS_ADDRESS_OF STATUS
parameter is not configured, the CCCM Block automatically updates the status to “Good Non
Cascade” when the communication with slave is OK or “Bad No Communication with last value” and
“Non-Specific”, if communication fails.
