Connection of measuring inputs or proximity sensors (external zero mark)
Procedure:
1.
Wire the power supply for the encoders. This must meet the same criteria as the load
power supply for the SIMOTION C.
2.
Connect the shielded signal line to the encoders.
3.
Remove a sufficient length of the cable sheath at the control end so that you can connect
the shield to the shield connecting element and the free cable ends to the front connector.
4.
Wire the signal line to the front connector.

Figure 5-17 Overview of connections for measuring inputs or proximity encoders
Note
For the assignment of the front connector and the description of the I/O interface, refer to
chapter I/O interface (Page 68).
Connection of additional actuators/encoders
If you wish to connect additional actuators/encoders to the SMs on the I/O bus, proceed in
the same way as for connecting digital inputs/digital outputs to the SIMATIC S7-300.
See the
S7-300, M7-300 Automation Systems, Module Data Manual.
The digital inputs/digital outputs on the central I/O system are recorded/output at a refresh
rate of approx. 1 ms.
