- 52 6.11 Monitor Function
6.11.1 Monitor condition setting
(a) Monitored CPU module file
When monitoring after setting the monitor condition, the file displayed on GX
Developer is monitored.
Choose [Online] [Read from PLC] on GX Developer, and match the file name of
the CPU module to be monitored with the file name on GX Developer.
(b) When there is no file register setting
When monitoring the file register which is not specified, 0 is displayed. (For the
Universal model QCPU, FFFF
(c) Device assignment of CPU module and GX Developer for monitor
When executing monitor, match the device assignment of the CPU module with
that of GX Developer.
(d) When monitoring the intelligent function module buffer memory
When monitoring the buffer memory of the intelligent function module, the scan
time takes longer, as well as when executing the FROM/TO instruction.
(e) When multiple users are performing simultaneously
Multiple users can perform monitoring at the same time.
When multiple users are performing monitoring at the same time, take note of the
following:
• High speed monitoring can be performed by increasing 1k step in the system
area for other station's monitor file when formatting of program memory.
Up to 15 stations can be set as the station monitor file, but the program space
will be reduced.
• If the monitor condition and/or monitor stop condition are set, only one user
can perform monitoring.
(f) Status where monitor stop condition can be set
The monitor stop condition can be set only in the ladder monitor.
(g) When the same device is specified for conditions
When the same device is specified as the monitor condition and monitor stop
condition, specify "ON" or "OFF".
(h) When step No. is specified for monitor condition
The monitoring conditions will not be established unless the following specified
steps commands are executed when "Step No." has been specified for the
monitoring conditions.
• When skipping steps specified with the CJ instruction, the SCJ instruction
and the JMP instruction.
• When the specified step is the END instruction, the FEND instruction exists
while the program is running, and the END instruction is not executed.
(i) During monitor condition registration
Do not reset the CPU module while monitoring conditions are being registered.
