EtherNet/IP Settings

ISDU Data Settings

ISDU Response Timeout (1-10000)

Process Data Settings

PDI Data Block Size (To PLC)

(Default: 36-bytes)

The configurable PDI data block length. Optional lengths are:

• 4-bytes (header only)

• 8-bytes (4 bytes data)

• 16-bytes (12 bytes data)

• 24-bytes (20 bytes data)

• 36-bytes (32 bytes data)

PDI Data Block Format (To PLC)

(Default: Word-16)

Data format of the PDI data block to be transferred to the PLC(s)in the Class 1 and/or Write-to-Tag/File PDI Transfer Modes. Valid PDI Data Formats are:

• Byte-8(8-bit or SINT)

• Word-16 (16-bit or INT)

• Dword-32 (32-bit DINT)

• This setting is not used for the SLC, PLC-5 and MicroLogix PLCs which are always Word-16.

PDI Data Byte-Swap Method

(Default: Word (16-bit) byte swap)

If enabled, the IO-Link Master swaps the data bytes in word (2 byte) format or dword (4 byte) format. Supported values are:

• Word (16-bit) byte-swap - data is byte-swapped in word format

• Dword (32-bit) byte-swap - data is byte-swapped in dword format

The byte swapping must be set correctly in order to convert from IO-Link (big-endian byte order), to EtherNet/IP (little-endian byte order).

24-bytes = all data

32-bytes = all data

34-bytes = 32 bytes data, 2 pad bytes

36-bytes = 32 bytes data, 4 pad bytes

The following optional lengths are shown with the event code included:

• PDO Data Format = dword (32-bit):

• 4-bytes = event code dword

• 8-bytes = event code dword, data dword

• 16-bytes = event code dword, 3 data dwords

• 24-bytes = dword event code, 5 data dwords

• 32-bytes = dword event code, 7 data dwords

• 36-bytes = dword event code, 8 data dwords

PDO Block Data Format (From PLC)

(Default: Word-16)

This is the data format of PDO data block received from PLC(s) in the Class 1 or Read-from-TagOrFile PDO Transfer Modes. This includes these formats:

• Byte-8 - (8-bit)

• Word-16 - (16-bit)

• Dword-32 - (32-bit)

• The Data Block Format is independent of the PDO Data Byte-Swap Method.

• This setting is not used for the SLC, PLC-5 and MicroLogix PLCs which are always Word-16.

PDO Data Byte-Swap Method

(Default: Word (16-bit byte swap)

If enabled, the IO-Link Master swaps the data bytes in word (2 byte) format or dword (4 byte) format. Supported values are:

• 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

The byte swapping must be set correctly in order to convert from EtherNet/IP (little-endian byte order), to IO-Link (big-endian byte order).The byte swapping must be set correctly in order to convert from EtherNet/IP (little-endian byte order), to IO-Link (big-endian byte order).

Clear Event Code In PDO Block

(Default: False)

If enabled, the IO-Link Master expects the first 2 bytes, word, or dword of the PDO block to be used for event code handling. Valid values are:

• True  = expect an event code

• False = no event code, expect only PDO data

Clear Event Code After Hold Time

(Default: True)

If enabled, the IO-Link master will clear any event code reported in the PDI data block after the Event Active Hold Time. Valid values are:

• True  = clear the event code after the hold time

• False = do not clear the event code after the hold time

Active Event Hold Time (1-65535)

Valid units are:

• ms (milliseconds)

• sec (seconds)

• min (minutes)

• hours

• days

Clear Event Hold Time (1-65535)

(Default: 500ms)

Once an event code has been cleared, the time an event code stays cleared in the PDI block before another event code can be reported. The valid range is 1-65535.

Valid units are:

• ms (milliseconds)

• sec (seconds)

• min (minutes)

• hours
