Can you tell me how to set alarms and perform contact output (DO output) with SMARTDAC+ GX/GP series?

This requires a DO output module. The following is an example in which the DO output module is installed into slot 1, and DO output is performed at alarm level 1 on DO channel 1. If your module is already installed, you must reconfigure it.
Set alarms (alarm level 1), turn detection ON, set the output destination to “Relay,” select output destination number “0101,” and then tap Save. For details, see “Advanced Operation (Various settings and operation)” in the first step guide (IM 04L51B01-02EN).
