EtherNet/IP Settings Parameters
PDO Data Block Size (From
PLC)
Default: 32-bytes
The configurable PDO data block length. Supported optional lengths are:
• Event code not included:
- 4-bytes = all data
- 8-bytes = all data
- 16-bytes = all data
- 24-bytes = all data
- 32-bytes = all data
- 34-bytes = 32 bytes data, 2 pad bytes
- 36-bytes = 32 bytes data, 4 pad bytes
• Event code included - PDO Data Format = Byte8:
- 4-bytes = 2 byte event code, 2 data bytes
- 8-bytes = 2 byte event code, 6 data bytes
- 16-bytes = 2 byte event code, 14 data bytes
- 24-bytes = 2 byte event code, 22 data bytes
- 32-bytes = 2 byte event code, 30 data bytes
- 34-bytes = 2 byte event code, 32 data bytes
- 36-bytes = 2 byte event code, 32 data bytes, 2 byte pad
• Event code included - PDO Data Format = word (16-bit):
- 4-bytes = event code word, data word
- 8-bytes = event code word, 3 data words
- 16-bytes = event code word, 7 data words
- 24-bytes = event code word, 11 data words
- 32-bytes = event code word, 15 data words
- 34-bytes = event code word, 16 data words
- 36-bytes = event code word, 16 data words, pad word
• 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
- 34-bytes = dword event code, 7 data dwords, 2 data bytes
- 36-bytes = dword event code, 8 data dwords
PDO Data Block Format (From
PLC)
Default: Word-16
Data format of PDO data block received from the PLC(s) in Class 1 or
Read from TagOrFile PDO Transfer Modes. Formats include:
• Byte-8 (8-bit)
• Word-16 (16-bit)
• Dword-32 (32-bit)
Note: 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.
