 41 Usage of the Digital I/O module as a digital output
There is a Digital Xx-x submenu for each digital I/O module of the device. "X" designates
the slot in the terminal compartment, "x-x" the terminals within this slot. The most
important parameters of this submenu are Operating mode, Digital input source and
Contact type.
A digital output can be used to
• output the state of an alarm (if an alarm has been configured →  74)
• transmit the status of a digital input (if a digital input has been configured →  64)
To configure a digital output, proceed as follows:
1. Navigate to Setup → Advanced setup → Input/output → Digital Xx-x, where Xx-x
designates the digital I/O module to be configured.
2. Go to the Operating mode parameter and select the Output passive option.
3. Go to the Digital input source parameter and select the alarm or digital input to be
transmitted.
4. Go to the Contact type parameter and select how the internal state of the alarm or
digital input is to be mapped to the digital output (see table below).
