2 Instruction Descriptions
Use DeviceType to specify the device type. Specify _DeviceNXUnit for an NX type of IO-Link master
unit and _DeviceEcatSlave for a GX type of IO-Link master unit. The variable used to specify the device
is determined by the specified device type.
For this instruction, it is determined as follows:
To specify the NX type, use NxUnit to specify the device. In this case, EcatSlave is not used. To NxUnit,
pass the device variable that is assigned to the device to specify.
To specify the GX type, use EcatSlave to specify the device. In this case, NxUnit is not used. To Ecat-
Slave, pass the device variable that is assigned to the device to specify.
Use PortNo to set the port number to which the IO-Link device is connected.
The number of ports differs depending on the type of IO-Link master unit.
NX type: 1 to 4
GX type: 1 to 8
The data type of DeviceType is enumerated type _eDEVICE_TYPE.
The meanings of the enumerators of enumerated type _eDEVICE_TYPE are as follows:
Enumerator
_DeviceNXUnit
_DeviceEcatSlave
Use the DeviceObj input variable to specify the object parameter for the IO-Link device from which data
is read.
The data type of the DeviceObj input variable is structure _sIOLOBJ_ACCESS. The specifications are
as follows:
Name
DeviceObj
Index
Subindex
Use the RetryCfg input variable to set retry processing for instruction execution.
The data type of RetryCfg is structure _sIOL_RETRY_CFG. The specifications are as follows:
Name
RetryCfg
TimeOut
RetryNum
Data read from the IO-Link device is stored in
2-972

NX Unit is specified.
EtherCAT slave is specified.
