PDO Byte-Swap Method
Default:
No byte-swap
If enabled, the IOL MA8 PN DI8 swaps the data bytes in word (2 byte) format or
dword (4 byte) format. Options include:
–
No byte-swap
: Data passed through as received
–
Word (16-bit) byte-swap
: Data is byte-swapped in word format
–
Dword (32-bit) byte-swap
: Data is byte-swapped in dword format
–
Reverse registers
: Data passed through after being reversed
Append PDO to PDI Data
Default:
False
If selected, the IOL MA8 PN DI8 appends any PDO data to the end of the PDI data.
–
True
(enable check box): Append PDO data.
–
False
: Do not append PDO data.
Clear Event Code in PDO Block
Default:
False
If enabled, the IO-Link expects the first word of the PDO block to be used for event
code handling.
Values are:
–
True
(enable check box): Expect event code.
–
False
: No event code, expect only PDO data.
Clear Event Code After Hold Time
Default:
True
If enabled, the IOL MA8 PN DI8 clears any event code reported in the PDI data block
after the Event Active Hold Time.
Values are:
–
True
(enable check box): Clear event code after hold time.
–
False
: Do not clear event code after hold time.
Active Event Hold Time
Default:
1000 ms
If Clear Event Code After Hold Time is enabled, this is the time event code is held in
the PDI block before it is cleared.
Valid range: 1-65535
Valid units are:
–
ms (milliseconds)
–
sec (seconds)
–
min (minutes)
–
hours
–
days
Event Hold Time Units
Valid units:
–
ms (milliseconds)
–
sec (seconds)
–
min (minutes)
–
hours
–

“Modbus TCP Settings” parameters [...]
Field name
Function
Because both IO-Link and Modbus TCP use big-endian byte ordering,
byte swapping typically is not required for word and dword data. Byte
swapping is most commonly required when sending byte (8-bit) data to
the IO-Link device and it is desired to send the least significant byte of
the holding register first. For these cases, word (16-bit) byte-swap is
typically used.
