Fipio Diagnostics
Diagnostics mode
Introduction In online mode it is possible to perform general diagnostics on the bus errors and device faults.
This diagnostic is possible by using screens available in the PL7 or the bits and system words managed by the application software.
Two modes are available: z z
FIPIO bus monitoring, device monitoring with or without a fault history.
Communication counters
Every configured connection point (including connection points 0 and 63) has a report variable. This variable contains the communication counter and performance values.
This variable has: z z z the activity counters numbered from 16#00 to 16#20 and standardized as
WORLDFIP, the error counters numbered from 16#21 to 16#7F and standardized as
WORLDFIP, the manufacturer counters numbered 16#80 to 16#FF these counters are not standardized as WORLDFIP.
The error counters change when there are communication errors on the FIPIO bus.
Diagnostics screens
Four screens display the status of the various counters and thus the communication errors: z z z z
The FIPIO bus monitoring screen provides a global view of the FIPIO bus, it displays the communication errors on the whole bus.
The Device monitoring screen provides a synthesis per connection point; it features all the connection points and indicates the status of the error counters per connection point.
The Device monitoring at connection point n screen shows all the counters and their status at a given connection point.
The Communication fault history screen is a fault history, which dates and retains the fault counter statuses to provide a trace.
Only one screen of each type can be open (one per connection point for the third type). If you try to open a screen which is already open, it will appear instantaneously.
