Tab. 13: Inputs and outputs for the higher-order PLC
The inputs and outputs are configured using the CMMT-ST plug-in è online help
for the CMMT-ST plug-in.
The signals of inputs STO-A/B are low active, so they are marked with #.

7.4.2 [X1C], reference switch/limit switch
The connection [X1C] is located on the front of the device and is used to connect
the reference switch or a limit switch. The switching logic of the input can be
parameterised (PNP logic or NPN logic).

7.4.3 [X2], encoder interface
The encoder interface [X2] is located on the front side of the device. Communica-
tion with the encoder is performed via this interface. The encoder signals are
received, and the encoder is supplied with voltage.
The following encoders are supported:
– Incremental encoders with AB signals (quadrature encoder)
– Absolute encoders with BiSS C protocol

7.4.4 [X18], standard Ethernet
The interface [X18] is located on the front of the device. The following can be
performed via the interface [X18] using the commissioning software:
– Diagnostics
– Parameterisation
– Controller
– firmware update
The interface fulfils the requirements of standard IEEE 802.3:2012. The interface
is galvanically isolated and intended for use with limited cable lengths.
The connection [X18] is designed as an RJ45 bushing. 2 LEDs are integrated into
the RJ45 bushing. The green LED lights up if the interface is activated. The yellow
LED flashes when communication activity is detected.
