Response Time

The response time is the time that elapses from the change of an input until setting of an output of
the IP 265.
In the preceding section, we already mentioned the program execution time of the FPGA. For the
assessment of the response time of the IP 265, additional delays must be considered when using
the 24 V inputs and 24 V outputs.
The response time consists of the following three components:
•

Input delay

• Program execution period
•

Output delay
