Calculating response time
Information about the response times of the IO controller can be found in the manual of the
IO controller used.
The "S7 Distributed Safety" add-on package contains an Excel file "s7fcotia.xls" for
calculating maximum response times. You can find the current version of this table on the
Internet at the following address:
"s7coti (http://support.automation.siemens.com/WW/view/en/19138505
)",
Entry -ID 19138505
Detailed information for the calculation of the response time of the F-system can be found in
the "Safety Technology in SIMATIC S7" system manual
(http://support.automation.siemens.
