Mode selector
The S1 / S2 mode selectors are used to switch between the operating modes "Local 1,"
"Local 2," "Local 3," and "Remote/Automatic." To do this, plugs S1 and S2 must be
connected to any sockets (e.g. device inputs, communication bus control bits, etc.).
The table below shows the operating modes depending on the signal states of mode
selectors S1 and S2:
Table 4- 5

The different operating modes for enabling the control stations can be used to specify the
switch authorizations for the individual control stations:
● Local control [LC]
● PLC/PCS [DP] or PLC/PCS [PN]
● PC [DPV1] or PC/OPC-UA [HMI]
● Operator panel (OP)
Only the following are active:
● the operating mode set by plugs S1 and S2 of the "Control Stations" function block and
● the enables selected there.
Example of a dynamic mode selection as a function of time:
