Automation system
60 System Manual, 01/2023, A5E03461182-AK
Example: Web server simplifies maintenance of treatment plants
Automation task:
Implementation of a user interface for fault management of a treatment plant.
Feature:
Treatment plants operate fully automatically, they are not manned. The operator optionally
receives an SMS if a fault occurs. For diagnostics, the operator directly accesses the
corresponding web sites.
Solution:
Creation of user sites for the web server of a SIMATIC S7-1500 CPU. The customer can make
changes to the web sites himself, e.g. the mobile number for the SMS messages, settings in
the CPU or the message texts.
Benefits
The web server provides you with the following advantages:
• Access via web browsers to a SIMATIC S7-1500 with plant-relevant operating data
• Display of service and diagnostics information over large distances
• Access restrictions for unauthorized users
Additional information
A detailed description of handling the web server can be found in the Function Manual
"SIMATIC S7-1500 web server" SIMATIC S7-1500 Web server
(https://support.industry.siemens.com/cs/de/en/view/59193560).
4.4.4 Safety
For fail-safe operation of your plant, program the F-CPUs of the SIMATIC S7-1500. Use the
"STEP 7 Safety Advanced" option package of the TIA Portal for this purpose. In combination
with the TIA Portal, the F-CPUs offer optimal integration of fail-safe systems into your
engineering environment; one controller, one communication system and one engineering
platform for standard and fail-safe automation:
• Integration of safety technology
• Instructions approved by German Technical Inspectorate for frequently required safety
applications
• Integration of safety-related functions up to SIL 3 according to IEC 61508:2010 or PL e and
category 4 according to ISO 13849-1:2015 or according to EN ISO 13849-1:2015
• Uniform engineering for standard and safety automation
• Simple documentation of safety-related changes via the F change history in STEP 7 Safety
• Support in the acceptance of the safety program and no renewed acceptance of the safety
program after changes in the standard program
