Diagnostic block for AS-i master modules with visualization via HMI or web browser
For use of the ET 200SP modules CM AS-i Master ST and F-CM AS-i Safety we provide a separate diagnosis package. 109479103
The presented diagnostic block for AS-i master modules supports the following and other AS-i masters from the SIMATIC product range:
- DP/AS-i Link 20E
- DP/AS-i LINK Advanced
- IE/AS-i LINK PN IO
- CP 343-2P, CP 343-2
AS-Interface slaves are connected with a SIMATIC controller via gateways or communication modules. An individual evaluation of the diagnostic data of the AS-i masters and slaves in the STEP 7 user program supports the plant operator searching the failure in case of service, so that the failure-free operation could be re-established fast.
The requirement in this application is to show how with the aid of a universal diagnostic block from a library all for S7-300/400 and S7-1500 actual available AS-i master systems can be common diagnosed and visualized.
To simplify the AS-i diagnostic for the user, the present library contains a number of blocks to be able to conveniently evaluate and visualize the diagnostic data:
- in the user program: The read AS-i diagnostic data is ready for individual further processing in a data block.
- on HMI panels: The library includes blocks that serve as interface between HMI panel and CPU.
- via web browser: SIMATIC CPUs with PROFINET interface provide the opportunity to access CPU variables with the help of individually designed web pages provided by the system. The library includes blocks that serve as interface between user-defined web pages and CPU.
The diagnostic blocks were realized for the S7-300/400 and S7-1500 CPU.
WinCC flexible visualization
The diagnostics user interface is realized using the depending AS-Interface visualization block:
