13.2.4 External value to control analog output (IO+ version)
If an external device (e.g. PLC) would like to control extraction command through eNod4 analog output, so that output
must be set on level on request function. In this configuration eNod4 will copy external value to control analog
output parameter on analog output in current and voltage.
The external value parameter is expressed in 0.01% of full scale of analog output current or voltage.
