SIMOTION C with centralized I/O
Function
... is the motion control module. The SIMOTION C supplies the I/O bus
with 5 V; communicates over the I/O bus (backplane bus) with the I/O
modules.
You can use the integrated fast digital inputs of the SIMOTION C as:
• B1 to B4: As homing inputs (C230-2, C240)
• M1 and M2: As inputs for measuring inputs - local measuring
(C230‑2, C240)
• B1 to B4: As inputs for global measuring (C240, C240 PN)
• Freely addressable process inputs
You can use the integrated fast digital outputs as:
• Fast output cams
• Freely addressable process outputs
Drive units with a ±10 V analog interface or stepper drives with a pulse/
direction interface can be connected to the onboard drive interface
(C230-2, C240). With the C240, the analog interfaces can also be used
as available process outputs.
Incremental encoders or absolute encoders can be connected to the
measuring system interface (C230-2, C240). With the C240, free re‐
maining encoder inputs of an axis channel can be used as the input for
a 16-bit up/down counter.
... converts the line voltage (120/230 V AC) into an operating voltage of
24 V DC to supply the SIMOTION C.
... adapt various process signal levels to the SIMOTION C (digital input/
digital output modules and analog input/analog output modules).

... relieve the CPU of computation-intensive tasks, for example, count‐
ing.
