Technical Specifications
10.6 Using the ET 200M in the potentially explosive area zone 2
Switchover Time in the Case of Redundancy
The switchover times, dependent on the mode and configuration amounts to:
DP master system
S7-400H
S7-software
redundancy;
S5-115H / 155H
If the response monitoring time is set greater than 30 ms or 70 ms, the switchover time
corresponds to the set monitoring time.
Delay time of the input / output modules
The delay time of the input / output modules can be derived from the technical specifications
of the modules (refer to the "S7-300 automation system, module specifications
(http://support.automation.siemens.com/WW/view/en/8859629)" reference manual).
