3.2 Typical Configuration of CTEU-EP

Below is an example with a fixed dual port configuration with a separate status for the CTEU-EP bus node. This allows for maximum device type size, and keeps the I/O in equal sizes.

Informationen

The shown configuration also adds an additional Status-Byte for diagnostics without the need to change the default DIL-Switch settings by using

Comm. Format “Data – SINT – With Status”

and assembly instance 103 as

Status Input

.

Note

• The CTEU-EP must be configured with an assembly instance large enough for the IO-link device.

Refer to the CTEU-EP manual. The size of the IO data determined by the assembly instances must also be large enough for the IO-link device.

• The I/O-size of the CPX-CTEL-LK module has to be large enough to hold the data of the connected

IO-Link devices. Refer to the CPX-CTEL-LK manual for details on the corresponding settings of the

DIL switches

Note

In both, the CPX and CTEU, the process data will be automatically transferred to the device. However, due to the little-endian / big-endian difference in EtherNet/IP vs. IO-Link, the byte order will be swapped. This must be handled in the controller logic.
