Example PLC Program Tag Definitions
6.7. Example PLC Program Tag Definitions
The following tag definitions apply to the example IO-Link Master PLC program.
Tag Name Value Range Description
PrtN_Operational
(init state = false)
BOOL
Controlled by the subroutine, the port operational
status. The port must be operational before
communication to the IO-Link port is allowed.
• 0 = false
• 1= true
PrtN_PdiValid
(init state = false)
BOOL
Controlled by the subroutine, the PDI (Input Process
data block) valid status.
• 0 = false
• 1= true
PrtN_PortInfoValid
(init state = false)
BOOL
Controlled by the subroutine, the port information
valid status. The port information must be retrieved
before the device can become operational.
• 0 = false
• 1= true
PrtN_SendBlkgISDUReq
(init state = false)
BOOL
Controlled by the User or some other part of a PLC
program, directs the subroutine whether to send a
blocking ISDU request to the IO-Link Master.
• 0 = false (do not send message)
• 1= true (send message)
PrtN_SendNonBlkISDUReq
(init state = false)
BOOL
Controlled by the User or some other part of a PLC
program, directs the subroutine whether to begin
the non-blocking ISDU request process. If true, the
subroutine sends a non-blocking ISDU request to
the IO-Link Master.
• 0 = false (do not send message)
• 1= true (send message)
