2.2.2Installing a PLC with Distributed Configuration

To install a PLC in a distributed configuration, you have a choice of parallel/symmetrical and serial communication. The following table shows which interfaces and connecting cables can be used to connect the various expansion units (EUs/ERs) to the CC in a distributed configuration.

6ES5 707-5AA00 V45551-F21-B5 up to 3000 m

Cable connection

6ES5 722-2xxxx

Fiber optic cable up to 1500 m

1)The last IM 310 or IM 314 always requires a 6ES5 760-1AA11 terminator.

The ER 701-2 and ER 701-3 always additionally require an IM 306 for communication via an IM 304, IM 307 or IM 308.

To install a PLC in a distributed configuration, you must observe the following conditions:

SWith the IM 301/IM 310 pair of interface modules, you can only use I/O modules (DI, DO, AI, AO) and IPs without page addressing in the EUs.

SWith the IM 304/314 pair of interface modules, you can use all IPs, CPs and I/O modules in the EU 185U.

Note

The IM 307/317, IM 308/318 and IM 308-B/318-B each have their own manual (see catalog).
