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 script for Ethernet connection:

The same script can be used for MELSECNET/H connection, MELSECNET/10 connection and Ethernet connection.

//Script of Screen No. 1

//If Station 1 is not a control station, the screen is changed to that of Station 2. if([1-1:b:SM1515]==OFF){

[w:GD100]=2;

}

//Script of Screen No. 2

//If Station 2 is not a control station, the screen is changed to that of Station 1. if([1-2:b:SM1515]==OFF){

[w:GD100]=1;

}
