6.3 Parameter description
6.3.1 Runtime and error monitoring
The ru-parameters serve for monitoring of the program flow.
ru.00
Status
Address 0200h
Program status
no prog
no program loaded
prog OK
program loaded
prog corrupt
program checksum error
Control status
run
Program runs
Stop
Program stopped
breakpoint
Program is on break point
Error status
err_cyctime
The adjusted cycle time was exceeded
err_watchdog The length of the last PLC cycle exceeded the
maximum value, the PLC program was stopped.
ru.01
cycle time
Address 0201h
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
Address 0202h
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
Address 0203h
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
Address 0204h
ru.05
max. process time
Address 0205h
ru.06
response time
Address 0206h
ru.07
process time
Address 0207h
ru.08
idle time
Address 0208h
The cycle time of a PLC program flow is composed of:
response time
Time of recognizing the new program cycle up to the call of the PLC
program
process time
Time, when the PLC program as well as all accesses by CoDeSys
and COMBIVIS are processed.
idle time
Remaining time up to the next program cycle.
Parameter ru.04 / ru.05 displays the minimum/maximum process time and can be reset
by writing of any value.
