Input Description

EN   BOOL \    (enable)

With a FALSE->TRUE edge at the input EN, the processing of the function Function Block is activated. If the values are valid at the inputs, the function Function Block is processed. If the inputs are not valid, the processing is stopped and a corresponding error appears at the outputs ERR/ERNO. The function Function Block processing is always finished when the value at output DONE changes to TRUE. During the processing, signal changes at the inputs are noticed but not evaluated.

COM   BYTE \    (communication)

At input COM, the number of the serial input is defined.

COM = 1: COM1, COM = 2: COM2

IDX   BYTE \    (index)

The index number of the protocol, which is to be activated on the serial interface COM, is indicated at the input IDX. The assignment of the index number to the individual protocols is carried out in the configuration. If several protocols are defined in the setting “COMx ““ Multi[SLOT]”, the index number IDX = 0 corresponds to the protocol in the first place, and IDX = 1 corresponds to the protocol in the second place. In all other cases, if only one protocol is defined per interface, the index number IDX = 0 must be used.
