Control stations
• Control station - local control
In this case, the control devices are usually in the direct vicinity of the motor
and are wired to the inputs of SIMOCODE pro. The plugs of the "Control
Stations" function block must be connected to arbitrary sockets (normally the
function blocks for the basic units or the digital module inputs – BU Inputs,
DM Inputs) for the control commands to take effect.
Notice
The OFF command "LC OFF" is 0-active. This ensures that SIMOCODE pro
switches off the motor safely e.g. if a wire break occurs in the supply cable.
The precondition is that the control station is active.

• Control station - PLC/PCS
This control station is primarily intended for control commands from the
automation system (PLC/PCS) via the Cyclic Receive telegram from
PROFIBUS DP.
The plugs of the "Control Stations" function block must be connected to
arbitrary sockets, normally the function blocks for the cyclic PROFIBUS DP
bits (Cyclic Receive) for the control commands to take effect.
