Operating modes and mode selectors

Operating modes
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 operating mode, 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. Four operating modes
are provided for this purpose which can be selected via two 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 three operating modes in a system:
Operating mode
Key-operated switch
operation,
e.g. Local 1
Manual operation
e.g. Local 3
Remote operation,
(e.g. Remote/Automatic)
Table 4-1: Operating modes
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 switch operation has priority over all other
operating modes.
