Overview
• Master connection for the ET 200X distributed peripherals
system to AS-Interface using 12-pole connector
• Easy operation in the input/output address range of the
SIMATIC ET 200X
• No configuration of the CP for AS-Interface required
• Actuating up to 31 AS-Interface slaves according to
AS-Interface Specification V2.0
• Monitoring of the supply voltage on the AS-Interface shaped
cable
• Distinct increase in the number of inputs/outputs of the
ET 200X
■
Benefits
• Enables PLC functionality in degree of protection IP65 when
used in conjunction with BM 147 of ET 200X
• Can also be used without an additional enclosure in harsh in-
dustrial conditions thanks to the high degree of protection
IP67
• More flexibility and versatility in the use of ET 200X as the re-
sult of the distinct increase in the number of inputs/outputs
available
• Shorter start-up times through simple configuration at the
press of a button
• Reduction of standstill and servicing times in the event of a
fault thanks to the LED indicators:
- Status of the AS-Interface network
- Slaves connected and their readiness for operation
- Monitoring of the AS-Interface mains voltage
■
Application
The CP 142-2 enables connection of the ET 200X distributed
peripherals system to AS-Interface.
The module enables the actuation of up to 31 AS-Interface
slaves and, when using bidirectional slaves, up to 248 binary
