AS-Interface Master
Masters for SIMATIC S5
CP 2430
6
■
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
- 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
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
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.
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).
