The response time is the time from when the operation
command is given for a safety sub-function until the function
is activated.
The safety function response time (SFRT) is defined in IEC
61784-3.
When a fault occurs, the response time is calculated as
follows.
SFRT = specified response time + maximum permissible
time for delay in safety communication
