Setting Method

Set the Digital Input Collection Setting and Offset Setting of Digital Input Collection for each port
with the IO-Link Master Unit Configuration Tool.
Precautions for Correct Use
• For an offset setting value of the Offset Setting of Digital Input Collection, the bit position
00 of the last data in the input data serves as the offset position 0.
An example when the input data size is 4 bytes is shown below.
PD0
PD1
PD2
PD3
• If the offset value that exceeds the input data size is set, the bit data collected in the digital
input data is always 0.
Example 1: If the input data size is 2 bytes, the set range is enabled from 00 to 0F hex.
If the set range is 10 to FF hex, the bit data collected in the digital input data is always 0.
Example 2: If the input data size is 16 bytes, the set range is enabled from 00 to 7F hex.
If the set range is 80 to FF hex, the bit data collected in the digital input data is always 0.

•
Enable or disable the digital input collection for each port
in IO-Link Mode.
•
Digital input collection cannot be used in SIO (DI) Mode
or SIO (DO) Mode. This setting is ignored.
•
Specify the offset of the bit data to be collected in the in-
put data from the IO-Link device, when the digital input
collection is enabled for each port in IO-Link Mode.
•
When the digital input collection is disabled in IO-Link
Mode, this setting is ignored. This setting is also ignored
in SIO (DI) Mode or SIO (DO) Mode.
