6.3.1 IO-Link CALL (Turck)
Input variables
Address assignment of the IO-Link master module
Variable Data type Meaning
xREQ BOOL A rising edge triggers the send command.
Address assignement of
the IO-Link master mod-
ule The address assignment of the IO-Link master module depends on the fieldbus/
Ethernet protocol used and varies depending on the module used, see
Address
assignment of the IO-Link master module (Seite 49)
.
iIndexCap INT Function block instance: 251 to 254
xRD_WR BOOL 0 = read access
1 = write access
usiEntityPort USINT Address of the IO-Link port to be accessed.
IO-Link master = EntityPort0
IO-Link port 1…4 = EntityPort 0…4
uiIOL_Index UINT Fix value (65098): defines the access to be an IO-Link CALL
usiIOL_Subndex USINT Number of the IO-Link index which has to be written or read.
pbyRecord_IOL_Data Pointer to byte Definition of a possible sub index.
iLen INT Length of the data to be read or written. For the write access,
define the exact length if the data to be written.
IO-Link CALL Variable Data type Definition
Local IO itfModule Instance of the IO-Lin master, e.g. BL67-4IOL
PROFINET ID DWORD ID of the PROFINET slave The ID can be read using the “GetID”
method.
Example:
PROFINET Slave: BL67 gateway with IO-Link master at slot 2.
–
Instance of the BL… gateway. BL67_GW_EN
–
API: always "0"
–
SLOT 2
–
Subslot: always "1"

dwId:= BL67_GW_EN.GetID(API:= 0, SLOT:= 2, SUBSLOT:=1)
EtherNet/IP™ EtherNetIP
Device STRING Instance of the EtherNet/IP™ slave, e.g.: "Ethernet_IP_Slave"
Slot USINT Slot number of the IO-Link module in the BLxx station
Modbus TCP Slot USINT Slot number of the IO-Link module in the BLxx station
Slave STRING Instance of the Modbus TCP slave, e.g.: "Modbus_TCP_Slave"
