This word is used to determine the status of the digital I/O by reading one parameter. The bits in this word reflect the state of Pr x.03 to Pr x.10.
Source parameters define the parameter to be represented by the digital output terminal.
Destination parameters define the parameter each of the programmable inputs is to control.
Source parameters define the parameter to be represented by the digital output terminal.
This parameter selects the function of terminal T6 as follows:
OFF (0) = digital input
On (1) = digital output
These parameters select the function of terminals T3 to T5 as follows:
OFF (0) = digital input
On (1) = digital output
