Programming Using Io-Link - Omron NX Series Network Connection Manual

10. Programming Using IO-Link

This section describes how to create a program in Sysmac Studio and the procedure for acquiring
each of the process data and service data of the safety light curtain.
10.1 Sample Program for Acquiring Process Data
10.1.1 Reading the Power Supply Voltage of the Receiver
The values of the power supply voltage of the receiver are read from the process data that is
shared between the safety light curtain and the IO-Link Master Unit by cyclic communications.
The power supply voltage of the receiver is each split into the following two 1-byte parts before
being stored.
Device variable
Nx_Portx_Power_supply_high
Nx_Portx_Power_supply_low
x: Depends on the system configuration.

Stored information
Power supply voltage of receiver (upper 8 bits)
Power supply voltage of receiver (lower 8 bits)
Data type Description
Device variable
Becomes True when
BOOL
the process data of
port1 is enabled.
Device variable
The power supply
voltage supplied to the
BYTE receiver are stored to
the upper 8 bits and
lower 8 bits,
respectively.
Stores the power
supply voltage of the
WORD receiver that was
acquired in the sample
program.
(1) Executes the program when
the process input data is
enabled on the controller.
(N5_Port1_IN_Data_Enable
ON)
(2) Stores the power supply
voltage of the receiver that
are split and stored into two
1-byte parts to a 2-byte
variable
(SLC_Power_Supply).
