Parameter description
3.3.1 Runtime and error monitoring
The ru-parameters serve for monitoring of the program flow.
ru.00
Program status
Control status
Error status
ru.01
cycle time
This parameter indicates the cycle time adjusted by the PLC program in milliseconds.
This value is also used for the cycle time monitoring, a value of 0 ms means a free-run-
ning PLC program without cycle time monitoring.
ru.02
axis mode
The parameter indicates the axis configuration adjusted by the PLC program. There is a
differentiation between normal- and synchronous/cyclic operation.
ru.03
axis errors
The parameter indicates the axes which did not respond. This can have been released by
interruption of the cable to the axis or by switching off the axis. The value 0 means that all
monitored axes are connected correctly.
ru.04
min. process time
ru.05
max. process time
ru.06
response time
ru.07
process time
ru.08
idle time
The cycle time of a PLC program flow is composed of:
response time
process time
idle time
Parameter ru.04 / ru.05 displays the minimum/maximum process time and can be reset
by writing of any value.
GB - 18
Status
no prog
prog OK
prog corrupt
run
Stop
breakpoint
err_cyctime
err_watchdog
Time of recognizing the new program cycle up to the call of the PLC
program
Time, when the PLC program as well as all accesses by CoDeSys
and COMBIVIS are processed.
Remaining time up to the next program cycle.
no program loaded
program loaded
program checksum error
Program runs
Program stopped
Program is on break point
The adjusted cycle time was exceeded
The length of the last PLC cycle exceeded the
maximum value, the PLC program was stopped.
