Operation Mode Selector
Operation Mode Selector
You can use the control stations either individually or in combination. There are four different
operating modes you can switch between:
●
Local 1
●
Local 2
●
Local 3
●
Remote/Automatic: In this mode of operation, the communication must be carried out via
PLC.
Not all control stations are usually connected. If more than one control station (e.g. local and
PLC/PCS) is connected, it makes sense and is also mandatory to operate the control
stations selectively. 4 operating modes are provided for this purpose which can be selected
via 2 control signals (mode selectors). For each individual control station in every operating
mode, it can be stipulated if "ON commands" and/or "OFF commands" are to be used. The
operating modes are so controlled that only one operating mode is active at any one time.
Example: There are 3 modes of operation in a system:
Mode of operation
Description
Key-operated switch operation,e.g.
local 1
Only local control entries are admissible!
All other control stations are locked
Manual operation, e.g. local 3
Only operator panel control commands and local
control commands can be issued.
Remote operation, e.g.
remote/automatic
Only PLC/DCS control commands are permitted;
locally, only OFF commands are permitted
The key-operated Switch must be read in via an input to select these operating modes. The
Remote Switching operation should be controlled via the bus. The Key-operated Switching
operation has priority over all other operating modes.
The S1/S2 mode selectors are used to switch between the operating modes "Local 1", "Local
2", "Local 3" and "Remote/Automatic".
The S1 and S2 plugs must be connected to arbitrary sockets (e.g. device inputs, control bits
from PROFINET, etc.) for this.
The following table shows the operating modes, depending on the signal status of the S1
and S2 mode selectors:
