AL1431 IO-Link master with EtherCAT interface
56
Input Description Value range
PORT ADS communication port = 0x1000+port number • 0x1001: Port 1
• 0x1002: Port 2
• 0x1003: Port 3
• 0x1004: Port 4
IDXGRP AoE Index Group 0xF302
IDXOFFS Index Offset
• Bit 0…7: IO-Link Subindex
• Bit 8…15: 0x00
• Bit 16…31: IO-Link Index
e.g. access to index 21, subindex 0:
IDXOFFS = 0x00210000
ERRID ADS Error Code
• Bit 0…15: Error code of the IO-Link device
• Bit 16…31: ADS device error = 0x0700
e.g. access to parameters of the IO-Link de-
vice refused: ERRID = 0x07008023
9.3.12.2 Using CANopen over EtherCAT
The device supports mailbox communication via CANopen over EtherCAT (CoE). The CoE protocol
allows acyclic access to the IO-Link master and the connected IO-Link devices.
CoE uses the IO-Link Acyclic Command object area: Manufacturer-Specific Area (0x2000 - 0x5FFF)
(Ò/67)
A separate object area is available for each port.
u Observe the TwinCAT help!
In TwinCAT, access via CoE can be implemented via the following options:
1. [CoE – Online] tab in the device settings
2. Function blocks:
– FB_EcCoESdoRead: Read SDO of an EtherCAT slave
– FB_EcCoESdoWrite: Read SDO of an EtherCAT slave
Notes on the input assignment of the CoE function blocks:
Input Description Value range
sNetId AMS net ID of the EtherCAT master to which the de-
vice is connected
Depending on the project; e.g. 172.16.131.2.1
nSlaveAddr EtherCAT address of the port on the IO-Link master:
0x1000+port number
• 0x1001: Port 1
• 0x1002: Port 2
• 0x1003: Port 3
• 0x1004: Port 4
nSubIndex IO-Link subindex of the date
• Depending on the device; Ò IODD description of
the IO-Link device
e.g. subindex 0: 0x00
nIndex IO-Link index of the date
• Depending on the device; Ò IODD description of
the IO-Link device
e.g. subindex 21: 0x0015
Principle of acyclic command processing
General procedure of acyclic communication:
The IO-Link master can only process one CoE command request at a time. If another CoE
request is started during an active request, the device responds with an error (SDO abort code:
0x06090030).
1. Writing a command request
u In the command buffer (object 0x310n, subindex 0x01): Write command data
