Overview of the data I/O communication

What is data I/O communication?

This function enables cyclic (i.e. in xed intervals) data communications with the PROFINET devices. This

function provides high-speed control with several to several tens of milliseconds.

The communication can be controlled by referencing and updating the variables in the PLC, making it easy

to control the programs on the PLC side.

Communication settings for the data I/O communication, such as SendCycle (communication cycle) and

In a network with many connected devices (including the PROFINET devices), a network delay and/

or packet loss may occur when there is a heavy load on the network. Conduct a thorough verication

before the operation.
