Process and data communication
Thanks to its integrated interfaces, SIMOTION C supports both
process and data communication. The SIMOTION SCOUT
engineering system is provided for user-friendly communication
configuration and diagnostics.
Open-loop control and motion control functions
The open-loop control and motion control functions are executed
centrally on the SIMOTION C controller.
The functionality ranges from simple positioning to complex
motion control tasks over cams and interpolation.
Position-controlled motion control
Setpoint output/actual value acquisition
•
Position control with analog setpoint output
Per axis, the SIMOTION C240 Motion Controller provides one
analog output for the speed setpoint and one encoder input
for cyclic detection of the actual position value. In the case of
hydraulic drives, the setpoint for the positioning valve is
specified via the analog output.
•
Position control with pulse direction output for stepper drives
Per axis, the SIMOTION C240 Motion Controller provides one
pulse output for the position setpoint. Stepper drives can
either be operated without an encoder or be position-
controlled with an encoder.
•
Position control with digital setpoint output
The PROFIBUS DP interface with PROFIdrive or the
PROFINET interface for the C240 PN is available for this
purpose. The actual position value is retrieved and the speed
setpoint output over PROFIBUS DP or PROFINET.
•
Position control with mixed setpoint output
Analog, stepper and PROFIBUS drives can be used in a
mixed configuration on the SIMOTION C240 Motion Controller.
The channels of the 4 onboard interfaces can be used for
analog, stepper or hydraulic drives. PROFIBUS and
PROFINET drives can be operated as a mixed configuration
with the C240 PN.
•
Incremental position sensing (C240)
Incremental encoders supply counter pulses for the traversed
distance in accordance with their resolution.
It is usually necessary to search for homing references.
The following can be used:
- Rotary encoders
- Translatory encoders (length dimensions)
•
Absolute position sensing (C240)
Absolute encoders with a serial interface (SSI absolute
encoders) can be used.
It is not necessary to search for homing references.
•
Position control/position sensing via ADI 4 or IM 174
The ADI 4 (Analog Drive Interface for 4 Axes) or IM 174
(Interface Module for 4 Axes) module can be used to connect
drives with an analog setpoint interface.
The IM 174 also makes it possible to connect stepper drives
with a pulse direction interface.
Both modules are connected over PROFIBUS DP.
The following can be connected to one ADI 4 or IM 174
module:
- 4 drives
- 4 encoders
- Digital inputs and outputs
•
Isochronous PROFIBUS encoder

Overview of SIMOTION C connections
When dimensioning cables, you must always observe the
maximum permissible cable lengths.
If these maximum lengths are exceeded, malfunctions can
occur.
The permissible length of PROFIBUS DP cables depends on the
configuration.
