Fig. 7/4 Coupling of automation systems with ET 100U electronic terminator and SIMATIC S5 I/O modules

Serial coupling with SIMATIC S5 I/O modules and peripheral ￿devices (up to 3000 m)

The SIMATIC S5 I/O modules and the ET 100U electronic termi- nator provide the user of the TELEPERM M process control sys- tem with two further comprehensive ranges of I/O modules for optimizing the field connections.

Binary and analog input/output modules can be connected:

• I/O modules of the SIMATIC S5-115U programmable controller

I/O modules which can be connected in the ER 701-2 or ER 701-3 expansion racks (cf. page 7/4):

• I/O modules of the SIMATIC S5-135U and S5-155U program- mable controllers

I/O modules which can be connected in the EU 183U, EU 185U or EU 186U expansion units (cf. page 7/6):

• ET 100U electronic terminator

The ET 100U electronic terminator (see Catalog ST 50) enables direct connection of transmitters, final control elements, valves and lamps in the immediate vicinity of the process. Cabling and assembly costs can be greatly reduced by the omission of junc- tion boxes and as a result of the serial two-wire connection to the programmable controller.

Digital and analog I/O modules with intrinsically-safe inputs and outputs are available for the connection of devices in potentially explosive atmospheres.

The following are required to connect these SIMATIC peripheral devices:

•The interface module 6DS1 327-8AA in the AS 235 automation system

•The IM 318-8 interface module (6ES5 318-8MA12) in the ET 100U electronic terminator

•The IM 318-3 interface module (6ES5 318-3UA11) in the expansion units;

the adapter casing 6ES5 491-0LB11 in addition with the 701-2 expansion subrack.

The interface module 6DS1 327-8AA has 2 connections with

1 plug for 2 lines. Up to 32 devices can be connected in any sequence to each connection. Up to 3 interface modules

6DS1 327-8AA are permissible per AS 235 automation system.

A line may be up to 3000 m long up to the last device. However, the distances which can be covered depend on the type of cable used and the selected transmission rate.
