Meaning
Display
Floating point error (REAL) in:
209 FLOAT SYS-T
System task
Error in real calculation (e.g. divided by 0)
•
Check real calculation (program code)
210 FLOAT CYCL.-T
Cyclic task (PLC_PRG)
( g
y )
(p g
)
•
The error is eleminated as in a task overflow
211 FLOATTASK1
Task with Id.2
212 FLOATTASK2
Task with Id.3
213 FLOATTASK3
Task with Id.4
214 FLOATTASK4
Task with Id.5
215 FLOATTASK5
Task with Id.6
216 FLOATTASK6
Task with Id.7
217 FLOATTASK7
Task with Id.8
218 FLOATTASK8
Task with Id.9
219 overrun Cycl.-T
Time exceeded in
Cyclic task (PLC_PRG)
Task processing takes longer than the monitoring
time set
•
Set task runtime
•
If necessary, change monitoring time
•
Find out why the time has been exceeded by
checking the task-run times at the task
monitor
•
Swap out time-critical program parts in a
slower task
220 NoT-FKT-CREDIT
Insufficient units on the target
system
You tried to load a program with
technology functions to a PLC not equipped with
the corresponding units.
Use the T-variant of the PLC
230 No Program
PLC program error
No PLC program loaded
Load PLC program to PLC
240 ovrTransQueue
Error “Free CAN objects”
Overflow of send order memory
•
Reduce number of send orders
•
Prolong cycle time
241 ovr Receive
Error “Free CAN objects”
Too many receive telegrams
Reduce number of telegrams on bus
3.3.3
Fault trigger (L_FWM)
The FB
L_FWM
is used to transmit error messages to the PLC.
•
A TRIP, Fail-QSP, message or warning can be triggered in the PLC while the PLC program is
running.
•
The transmittee error number is stored in the history buffer of the PLC.
Tip!
This function block is described in the function library LenzeDrive.lib.
3.3.4
Error analysis using the history buffer
The PLC history buffer consists of 8 memory loaction which store the following information about the
active error and the 7 previous error, depending on their sequence of occurrence.
•
No. of system error message
•
Response to error (warning, message, TRIP, etc.)
•
Time of error (ref. to when the PLC has been switched on, e.g. “1234567 s”)
•
Occurrence of one error is sequence
