Mode selector switch
The mode selector switch determines the loading, starting and stopping of the
PLC-application by the fieldbus controller. This multifunction sliding switch
features 3 slide lock positions and a push-button function.
The sliding switch is designed for a number of operations in compliance with
EN61131T2.
Property damages due to set outputs!
Please note that set outputs remain set, when you switch the operating switch
from “RUN” to “STOP” during the current operation. Since the program is no
longer processed, software-related switch offs, i.e. by initiators, are ineffective.
Therefore, program or define all outputs, so that these switch to a safe mode at a
program stop.
Pre-programming the outputs for program stop!
You have the ability to program the behavior of the fieldbus controller so that the
outputs switch in a safe condition in the case of program stop.
For this WAGO-I/O-
PRO
allocates a function with
GET_STOP_VALUE
(library
“System.lib”), which serves to recognize the last cycle before “STOP”.
The mode selector switch position does not affect software start/stop!
The position of the operating mode switch does not prevent the starting and
stopping of the PFC application from WAGO-I/O-
PRO
.
