10-2 Communications Performance
This section describes the characteristics of PROFINET communications with PROFINET IO Devices
connected to a PROFINET IO Controller. Use this section for reference when planning operations that
require precise I/O timing.
The equations provided here are valid under the following conditions:
• All of the required PROFINET IO Devices are participating in communications.
• No errors are being indicated at the PROFINET Unit.
• Messages are not being produced in the network (from another company's configurator, for exam-
ple).
The I/O response time is the time it takes from the reception of an input signal at an NX Unit to the out-
put of the corresponding output signal at an NX Unit after being processed by the PLC’s user program.
