Diagnostic events for distributed

Refer to the "Diagnostics (PROFINET or PROFIBUS)": "Diagnostics events for distributed

I/O" (Page 345) for information on how to use this diagnostic information with these

communication networks.

The S7-1200 AS-i master CM 1243-2 allows the attachment of an AS-i network to an S7-

The actuator/sensor interface, or AS-i, is a single master network connection system for the

lowest level in automation systems. The CM 1243-2 serves as the AS-i master for the

network. Using a single AS-i cable, sensors and actuators (AS-i slave devices) can be

connected to the CPU through the CM 1243-2. The CM 1243-2 handles all AS-i network

coordination and relays data and status information from the actuators and sensors to the

CPU through the I/O addresses assigned to the CM 1243-2. You can access binary or

analog values depending on the slave type. The AS-i slaves are the input and output

channels of the AS-i system and are only active when called by the CM 1243-2.

In the figure below, the S7-1200 is an AS-i master controlling AS-i operator panel and I/O

module digital/analog slave devices.

To use AS-i with S7-1200 V4.0 CPUs, you must upgrade the AS-i Master CM firmware to

You can make this upgrade using a Secure Digital (SD) card.

It is recommended that you always update the AS-i CM firmware to the latest version

available (http://support.automation.siemens.com/WW/view/en/43416171)at the Siemens
