Display Statistics for Communication (H5/A6)
The statistics can be used during commissioning, service, etc.
Number of pollings is the number of pollings / "questions" sent out by the Control Unit to
all the units connected on the COM loop.
Parity fault is the received number of parity faults and % (faults in relation to pollings).
Number of bit faults is the received number of bit faults and % (faults in relation to
pollings).
No answer is the received number of answer faults / no answers and % (faults in relation
to pollings).
Bit length fault is the received number of bit length faults and % bit length faults in relation
to the pollings.
The number of Parity faults, number of bit faults, no answer and Bit length faults should be
normally "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.
All values are set to "0" after restart and/or after re-connection of COM loop (via menu
H8/S1).
