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
remaining 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).
Note:
All approved modules are listed in the
I/O modules approved for SIMOTION (Page 18).
... relieve the CPU of computation-intensive tasks, for example,
counting.
