4-5-1 Monitoring the System Run Status

• When writing data to the I/O memory in the CPU Unit with function blocks (e.g.,
using Send All Blocks, Expanded DO/AO Terminal to CPU Unit, or DO/AO Ter-
minal to CPU Unit for a Loop Control Unit and using user link tables and the
HMI function for an LCBjj), be sure that the words written to in the I/O
memory are not being used for any other purpose. If I/O memory words are
allocated to more than one purpose, the PLC system may act unexpectedly
and cause injury.
Take the following steps to execute run/stop commands.
1. Select Operation and Run/Stop Command from the Execute Menu. The
following dialog box will appear.
2. Select Hot Start to hot-start the Loop Control Unit/Board.
Select Cold Start to cold-start the Loop Control Unit/Board.
3. Click the Execute Button. As shown below, HOT START or COLD START
will appear in the Run Status Field.
4. To stop operating the Loop Control Unit/Board, select Stopped and click the
Execute Button.
Note The Run Status Field in the Run/Stop Command Dialog Box shows
the status of the dialog box opened or with the Execute Button
clicked. To refresh the status, click the Refresh Button.
Note 1. If Hot Start or Cold Start is selected after downloading function block data
that will change the operation cycle, a communications time-out error may
occur. In that case, close the Run/Stop Command Dialog Box for approxi-
mately 30 seconds, and then open the dialog box again and select Hot Start
or Cold Start.
2. A hot start or cold start will not be executed if Hot Start or Cold Start is se-
lected and the Execute Button is clicked when backing up data during op-
eration for the LCB01/LCB05 version 1.5 or higher, the LCB03, or the
LCB05D. If an attempt is made, an error will occur (error code: 110C).
It is possible to monitor or control the status of System Common Block of the
Loop Controller. The following items can be monitored or controlled. This func-
tion is mainly used for checking the load rate or execution errors.
