AS-Interface Master

Masters for SIMATIC S7

CP 142-2

■Overview

 

■Design

 

 

• 16 byte inputs and 16 byte outputs are used in the address

 

 

space of the ET 200X

 

 

• Operating statuses displayed by LEDs in the frontplate

 

 

• Display of the connected and activated slaves and their oper-

 

 

ational readiness by LEDs

 

 

• One pushbutton for switching the operating status, entering the

 

 

existing configuration and switching the display

 

 

• Connection of the AS-Interface cable to M12 connector

 

 

• Monitoring of the supply voltage on the AS-Interface cable

 

 

 

 

■Function

•Master connection for the distributed I/O system ET 200X at AS-Interface through 12-pin connector

•Simple operation in the I/O address area of SIMATIC ET 200X

•No need to configure CP for AS-Interface

•Addressing of up to 31 AS-Interface slaves according to the AS-Interface Specification V2.0

•Monitoring of the supply voltage on the AS-Interface shaped cable

•Considerable increase in the number of inputs/outputs of the ET 200X.

■Benefits

•In connection with the BM 147, the ET 200X enables PLC func- tionality in degree of protection IP65

•Can also be used in a rugged industrial environment without additional casing due to the high degree of protection IP67

•More flexible and extended application options of the ET 200X thanks to considerable increase in available inputs/outputs

•Shorter startup times due to easy configuration at the press of a button

•Reduction of standstill or service times in the event of a fault through LED displays:

-status of the AS-Interface network

-connected slaves and their operational readiness

-monitoring of the AS- Interface voltage level

■Application

The CP 142-2 can be used in two operating modes:

•Standard mode with BM 141/BM 142/BM 147

•A maximum of all 124 input and output bits of the AS-Interface slaves can be addressed.

•Extended mode with BM 147

A function call facilitates master calls in accordance with the AS-Interface Specification V2.0 (e.g. writing parameters). Calls are described in the manual. The manual also contains program examples.

System configuration

Parameter assignment

The CP 142-2 is parameterized with STEP® 7 basic package as of V2.1. Separate configuration for AS-Interface is not necessary.

The CP 142-2 enables the connection of the distributed I/O sys- tem ET 200X to AS-Interface.

This module can be used to activate up to 31 AS-Interface slaves and, if bi-directional slaves are implemented, up to 248 binary components.

Up to 6 CP 142-2 can be operated on the ET 200X.
