■ Overview<br />
■ Technical specifications<br />
AS-Interface Specification V 2.1<br />
4<br />
The CP 343-2 is the AS-Interface master for the SIMATIC S7-<strong>300</strong><br />
programmable controller and the ET 200 M distributed I/O<br />
station. The functions of the communications processor are as<br />
follows:<br />
• Up to 62 AS-Interface slaves can be connected and integrated<br />
analog value transfer (according to the extended<br />
AS-Interface specification V2.1)<br />
• Supports all AS-Interface master functions in accordance with<br />
the extended AS-Interface specification V2.1<br />
• Status displays for operatin g states and display of the<br />
functional readiness of connected slaves with LEDs in the<br />
front panel<br />
• Indication of errors (incl. AS-Interface voltage errors,<br />
configuration errors) with LEDs in the front panel<br />
• Compact enclosure designed to match the SIMATIC S7-<strong>300</strong><br />
