Siemens CP343-2P/CP343-2 Module
Manufacturer: Siemens

The CP 343‑2P communications processor is the AS‑Interface master for the SIMATIC S7‑300 and the ET 200M distributed I/O station, with user-friendly parameterizing options.

The CP 343-2 is the basic version of the module.

Features Applications Model
  • Connection of up to 62 AS‑Interface slaves
  • Integrated analog value transmission
  • Supports all AS‑Interface master functions according to the AS‑Interface Specification V3.0
  • Status displays of operating states and indication of the readiness for operation of connected slaves by means of LEDs in the front panel.
  • Fault indications (including AS‑Interface voltage fault, configuration fault) by means of LEDs in the front panel.
  • Compact enclosure in the design of the SIMATIC S7‑300
  • Suitable for AS‑i Power24V (from product version 2/firmware version 3.1) and for Standard AS‑i with 30‑V‑voltage.
  • Additionally for CP 343-2P: Supports the configuration of the AS‑Interface-network with STEP 7 V5.2 and higher
  • The CP 343-2P/CP 343-2 is the AS-Interface master connection for the SIMATIC S7-300 und ET 200M.
  • By connecting an AS-Interface, a max. of 248 DI/248 DO can be accessed per CP when using 62 A/B slaves with 4DI/4DO respectively.
  • The integrated analog processing function can be used to easily transfer analog signals (up to 62A/B analog slaves with a max. of 2 channels each or up to 31 standard analog slaves, each with a max. of 4 channels per CP).
  • The CP 343-2P is an enhancement to the CP 343-2 and has exactly the same functions. An existing STEP 7 user program for a CP 343-2 can be used for a CP 343-2P without limitations. The two assemblies are merely configured differently in STEP 7 HW Config, whereby the CP 343-2P offers additional possibilities. We recommend the CP 343-2P for these reasons.
