Step 3.
Set monitor screens.
For MELSECNET/H connection, MELSECNET/10 connection or Ethernet connection: (Common)
• Create a monitor screen with each object whose network setting is Station No. 1 on Screen No. 1 (1-1).
• Create a monitor screen with each object whose network setting is Station No. 2 on Screen No. 2 (1-2).
Step 4.
Change the screen switching device value in the script.
By selecting [Common]
[Script] [Script], create a script for each monitor screen that checks the
SM1515 status of the current monitor station, and if it is OFF (standby system), changes the station
number switching device value.
Set the trigger type of the script as [Ordinary] or [Sampling(about 3s)].
Screen scripts for MELSECNET/H connection and MELSECNET/10 connection:
The same script can be used for MELSECNET/H connection, MELSECNET/10 connection and Ethernet
connection.
POINT POINT POINT
When the MELSECNET/H network is connected to the redundant system only, SW56 (current
control station) can be set as the screen switching device.
In this case, even if the system switching occurs, the GOT always monitors the station number
that is currently the control station.
