Use a single lamp on the display unit to display in different colors the ON/OFF states of four different bit addresses.
If the state display is set to [Interlock Feature] or [Delay Feature], then [Show Interlocked Condition] has the highest priority followed by [Show In-Delay Status]. Consequently, the lamp may not display as expected. You can access this option from the [Switch/Lamp] dialog box, select the [Switch Common] tab and then select [Detail].
The four bit addresses specified on one lamp can be the bit addresses from different devices/PLCs.
