Remote Control

This section describes the command to set the SLMP compatible device or CPU module to the RUN status or STOP status by
a message from the external device.

Before the remote operation

When the accessed device or module is turned from off to on or the system is reset
after the remote operation
The information about the remote operation will be deleted.
Ex.
Even if the Remote STOP is executed when the switch of the CPU module is in the RUN status, the switch will return to the
RUN status after resetting the module.
When a remote password of the CPU module of the access destination is enabled
Remote operation from the external device is not available. An error will occur at the access destination, and an abnormal
response will be sent back to the external device. Unlock the remote password of the CPU module side, and resend the
request message.
Operable station in one command
Only one station can be operated remotely by one command.
When executing the remote operation to SLMP compatible device
It is recommended to use the UDP protocol for the remote operation. If TCP is used, the connection will be terminated when
resetting. Therefore, reestablishing of connection is necessary.

Remote RUN

This command executes Remote RUN to the access destination module.
Remote RUN can be executed when the switch of the access destination module is in the RUN status. Even if
the switch is in the STOP status, Remote RUN (command: 1001H) will be completed normally. However, the
access destination does not change to the RUN status.
