Note:
When loading comments, text within the program comments (for the project’s PLC) is
overwritten. When loading symbols, the local and global symbols for the PLC and programs
are first emptied.
If the file-card cannot be attached directly to the computer
When the file-card cannot be attached to the computer, it is possible to transfer comments and symbols to the
PLC file-card directly using the Transfer to PLC option above. To write the program to the file-card, use the
above steps to produce the program file on one of the computer’s disks. It is then possible to transfer the file
between the disk drive and the file-card on a PLC using the CX-Server memory-card component – please refer
to the CX-Server PLC Tools user-manual.
Program Monitoring
Program monitoring allows the power flow of a PLC program to be displayed whilst the PLC program is
running. Power flow is displayed by a thick line across items in the Ladder program that currently have power
flowing through them.
Note:
The data from several PLCs can be monitored at the same time. Ensure the program has been
downloaded and the PLC mode set to Monitor.
Use the following procedure to monitor a program.
1, 2, 3…
1. Select the Program object in the project workspace to display the Ladder program in the
Diagram Workspace.
2. Select
the
Work On-line
button from the toolbar. A confirmation message is displayed;
select the
Yes
pushbutton to connect to the PLC.
3. Select
the
Monitor Mode
button or
Run Mode
button from the toolbar. Monitoring can
only be accomplished in these PLC operating modes.
4. Select
the
Toggle PLC Monitoring
button from the toolbar to start monitoring power
flow in the Ladder program.
5. Select
the
Toggle PLC Monitoring
button from the toolbar to stop monitoring.
Note:
The PLC Monitoring function can be activated whilst in Mnemonics view.
The display format for the present values of operands of special instructions when monitoring
on the
Ladder Section
Window can be selected from the following data types. The same
display format must be used globally. To select the display format, click the desired button or
select
Monitoring Data Type
from the
View
menu.
•
Decimal
•
Signed Decimal
•
Monitor in Hex
The default display formats will be as follows if none of the above display formats is selected.
•
Named symbol will be monitored in the symbol data type.
•
Unnamed symbol will be monitored in the operand data type.
•
Two-word operations, such as for the MOVL instruction, will be monitored in 2-word
hexadecimal.
•
For present values displayed in formats other than hexadecimal, “D” is attached for 2-word
data and “L” is attached for 4-word.
Note:
The user can confirm whether a task (program) is executing or stopped (CS/CJ/CP-series CPU
Units only; CX-Programmer Ver. 4.0 or later). The following executing/stopped status is
displayed for every task (see note) in the project space.
Note:
Cyclic tasks only. Interrupt tasks not included.
•
Running: Indicated as READY (execution enabled) or RUN (executing status).
•
Stopped: Indicated as INI (not executing status) or WAIT (standby status).
