IO-Link Master Functions

IO-Link cyclic transmission function

This function communicates process data periodically with the IO-Link device connected to each channel.
With this function, information on the IO-Link device can be acquired and the IO-Link device can be controlled.
The communication cycle (cycle time) is automatically set to the minimum cycle time of the connected IO-Link device.
A maximum of 32 bytes process data can be communicated. The data size and structure vary depending on the connected
IO-Link module.
To validate output process data, turn on CH Output data valid flag (RY8 to RYF).
Precautions
When the minimum cycle time of the connected IO-Link device is less than 1.0ms, the cycle time is set to 1.0ms.
Operation mode
This function is enabled only in the following operation modes.
• IO-Link (standard) mode
• IO-Link (sink input) mode
Process data
Process data contains the following data.
■IO-Link (standard) mode
• Data masking results
• Input process data
• Output process data
■IO-Link (sink input) mode
• DI signal
• Input process data
• Output process data
Precautions
• When CH Input data invalid flag (RX8 to RXF) is on, input process data is an undefined value and cannot be used with
programs.
• When CH Output data valid flag (RY8 to RYF) is off, the IO-Link module notifies the IO-Link device that the output
process data is invalid. When output process data is invalid, IO-Link device operates in accordance with the specifications
of the IO-Link device being used.
