Mode selector
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
PROFIBUS DP, etc.) for this.
The following table shows the operating modes, depending on the signal
status of the S1 and S2 mode selectors:
Table 4-2: Operating modes depending on S1 and S2
The different operating modes for enabling the control stations can be used
to specify the switch authorizations for the individual control stations
• Local control station [LC]
• PLC/PCS [DP]
•PC [DPV1]
• Operator panel (OP)
Only the following are active:
• The operating mode set by the plugs S1 and S2 of the "Control Stations"
function block
• The releases selected on "Control Stations".
Example for a dynamic operating mode switching in relationship to time:
