AS-Interface Master

Masters for SIMATIC S5

CP 2430

■Overview

•Master connection for SIMATIC S5-115U to -155U

•Simple operation in the I/O address area of the SIMATIC S5-115U, -135U, -155U

•No need for CP configuration

•Two AS-Interface masters in one module

•Control of up to 2 x 31 AS-Interface slaves according to AS-Interface Specification V2.0

•Up to 496 binary elements can be controlled when using bi- directional slaves

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

■Benefits

•Saving on slots and costs because two AS-Interface masters are located on one module

•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

Master connection for:

•SIMATIC S5-115U:

CP can be inserted at CP slots in the central controller and expansion unit

•SIMATIC S5-135/S5-155U:

For exclusive use of I/O mode can be plugged into the I/O slots in the central controller and expansion unit; in cache mode, CP can be inserted at CP slots in the central controller and expan- sion unit

•Up to four CP 2430s can be used in the PLC, depending on PLC configuration.

■Design

•Two AS-Interface masters in one module

•Occupies a slot in SIMATIC S5

•For operation in the S5-115U an adapter casing is required.

•In I/O mode 32 byte are used in the I/O address space

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

•Connection of the two AS-Interface cables through connectors with terminal strip (solder-free connection with screw lock)

•One pushbutton per master unit for switching the operating status and entering the existing configuration

■Function

Each of the AS-Interface masters in the CP 2430 independently controls its own AS-Interface segment with up to 31 AS-Interface slaves. This allows control of a maximum of 2 x 31 AS-Interface slaves with a total of 248 binary sensors/actuators (496 when bi- directional slaves are used).

The front plate has separate status indicators for each master section, and a common LED matrix display for the active slaves.

The module address, page address and mode are set through encoding switches.

Two modes:

•Standard mode

Only the data bits of the slaves in the I/O address space of the PLC can be accessed in this operating mode. No master calls can be executed.

•Extended mode

Access to the master calls is provided through data handling blocks and the page interface in accordance with the AS-Inter- face Specification V2.0 (e.g. writing parameters).

User interface

There is a choice of three versions:

•I/O operation:

Only access to slave data in the I/O address space, no master calls

•I/O and page mode:

Access to slave data in the I/O address space and master calls through page access

•Page mode:

Access to slave data and master calls through page access
