AoE is suited for interruption-free access to the connected IO-Link devices during the operating time of
the device. Access to the IO-Link master with AoE is not supported.
The function blocks for using AoE are part of the
tc2_system.lib
TwinCAT library.
The following rules apply to the inputs of the ADS function blocks:
Input
Description
Possible values
PORT
ADS communication port =
IO-Link port number
0x1001
0x1002
...
0x1004
IO-Link port X01
IO-Link port X02
...
IO-Link port X04
IDXGRP
AoE index group
0xF302
IDXOFFS
Index Offset
e. g. access to index 21, subindex 0:
0x0021°0x00°0x00
Bits 0-7:
IO-Link subindex
Bits 8-15:
00000000
Bits 16-31:
IO-Link index
ERRID
ADS error code
e. g. access to parameters of the IO-Link
device refused: 0x0700°8023
Bits 0-15:
Error code of the IO-Link device
Bits 16-31:
ADS device error = 0x0700
