7 FUNCTION
(b) When "Device" is specified:
"Word Device" or "Bit Device" can be specified.
1) When "Word Device " is selected:
The monitoring operation is stopped when the current value of the
specified word device becomes the specified value.
A current value can be expressed in decimal digits, hexadecimal digits,
16-bit integral numbers, 32-bit integral numbers, or real numbers.
2) When "Bit Device" is specified:
The monitoring operation is stopped when the execution status of the
specified bit device becomes the specified value.
Either the leading edge or the fall can be specified for execution
condition.
(3) Precautions
(a) When monitoring after setting the monitor condition, the file displayed on GX
Developer is monitored. Match the file to be monitored by executing the
"New PLC Read" and file name on GX Developer.
(b) When monitoring the file register which is not specified, 0 is displayed.
(c) Perform the monitoring by matching the device allocation of the High
Performance model QCPU and GX Developer.
(d) 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) 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.
• The detailed condition setting for the monitoring can only be set for one
user.
(f) The monitoring detailed condition setting can only be set in circuit monitor.
(g) When the same device is specified as the monitor condition and monitor
stop condition, specify "ON" or "OFF".
(h) 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.
1) When skipping steps specified with the CJ command, the SCJ
command and the JMP command.
2) When the specified step is the END command, the FEND command
exists while the program is running, and the END command is not
executed.
(i) Do not reset the High Performance model QCPU while monitoring
conditions are being registered.
