Display Statistics for COM Loop (H5/A6)
The statistics can be used during commissioning, service, etc.
Number of Polling
is the number of polling ("questions") sent out by FT128 to the units
connected on the COM loop.
Parity fault
is the received number of parity faults and % parity faults in relation to the
polling.
Number of Bit faults
is the received number of bit faults and % bit faults in relation to
polling.
No answer
is the received number of answer faults / no answers and % faults in relation
to polling.
Bit length fault
is the number of bit length faults and % bit length faults in relation to the
polling.
The number of Parity faults, no. of Bit faults and No answer and Bit length faults must
normally be "0" or as close to "0" as possible. If not, there are some communication
problems that have to be investigated. Check the COM loop connections and the loop
units. Check that the COM loop cable is not placed too close to mains voltage cables, etc.
that might cause communication disturbance / problems.
Note: All values are set to "0" after a restart and/or when you re-connect the COM loop
(via menu H8/S1).
