4.1 Control stations
4.1.1 Description
Control stations are places from which control commands can be given to
the motor. The "Control Stations" function block is used for administration,
switching and prioritization of these different control stations.
SIMOCODE pro allows the parallel administration of up to four different
control stations. Dependent on the specified control function, up to 5
different control commands can be transmitted from every control station to
SIMOCODE pro.
• Local in the direct vicinity of the motor. Control commands via pushbuttons.
• PLC/PCS, switching commands are issued by the automation system
(remote).
• PC, control commands are issued via an operator control station or via
PROFIBUS DPV1 with the SIMOCODE ES software.
• Operator panel, control commands are issued via the buttons of the operator
panel in the switchgear cabinet door.
Examples of
control commands:
– Motor ON (ON>), Motor OFF (OFF) for a direct starter
– Motor LEFT (ON<), Motor OFF (OFF), Motor RIGHT (ON>) for a reversing
starter
– Motor SLOW (ON>), Motor FAST (ON>>), Motor OFF (OFF) for a Dahlander
circuit.
The plugs of the "Control Stations" function block must be connected to
arbitrary sockets (e.g. binary inputs on the basic unit, control bits from
PROFIBUS DP, etc.) for the control commands to take effect.
Up to 5 different control commands can be sent from each control station.
Up to 5 plugs (plug ON<<, ON<, OFF, ON>, ON>>) are available on the
function block for each control station. The number of active plugs depends
on the chosen control function. With a direct starter, for example, only the
plugs "ON>" and "OFF" are active.
