•Output setting when the EtherCAT
®
communication error/idling occurs. (IO-Link mode)
The behavior of IO-Link communication when EtherCAT
®
communication error/idling occurs can be set.
Process data outputs values can be held/cleared, and process data outputs can be valid/invalid.
The behavior of connected devices in each setting is as follows.
IO-Link master setting
(Fault/Idle output (IO-Link))
Operation of the connected IO-Link device
All outputs are turned OFF and
process data outputs remain valid.
Process data outputs remain valid and
hold the last data which IO-link master
received.
All outputs are turned OFF and
process data outputs become invalid.
Based on the IO-Link device’s output setting
function when the IO-Link communication
error/invalid is generated.
•I/O byte swap function
The data construction of each parameter for the byte swap function is based on the connected IO-Link
device process data size and the mapping size of the EtherCAT
®
communication process data as following.
When each size of process data matches.
E.g., device process data size: 8 bytes,
mapping size: 8 bytes,
8 bytes data value for construction: 0x0123 4567 89AB CDEF
When each size of process data does not match.
E.g., connected device process data size: 10 bytes,
mapping size: 16 bytes,
10 bytes data value for construction: 0x0123 4567 89AB CDEF GHIJ
0x0123 4567 89AB CDEF GHIJ 0000 0000 0000
0x2301 6745 AB89 EFCD IJGH 0000 0000 0000
0x6745 2301 EFCD AB89 0000 IJGH 0000 0000
0x0000 0000 0000 IJGH EFCD AB89 6745 2301
Note: When the mapping size of the EtherCAT
®
process data and the process data size of the connected device are different, swap the
byte with the blank byte zero.
