Type

Meaning
number of bytes after the TNS is not a
multiple of 4.
For PLC/PLC-2 word write commands:
1.A 2-byte ADDR field is expected after
the TNS word, but only one byte is
present.
2.There is an odd number of data bytes in
the command packet.
3.The ADDR value is odd (that is, it does
not specify a word address).
For PLC-3 read commands:
1.There is more than one byte of data after
the byte address.
2.Number of bytes to read is odd.
3.Number of bytes to read is zero.
4.Number of bytes to read is greater than
the maximum allowed in reply packet
(244).
5.Sum of packet offset and size of data in
words is greater than 65,535.
6.Sum of packet offset and size of data in
words is greater than the total transaction size
For PLC-3 bit write commands:
More than 4 bytes of data exist after the
PLC-3 address in the command message.
For PLC-3 write commands:
1.There is not at least 2 bytes of data after
the end of the block address.
2.There are an odd number of data bytes
after the end of the block address.
3.Sum of packet offset and size values
specifies more than 65,535 words.
4.Sum of packet offset and size is greater
than total transaction size.

For all PLC/PLC-2 read and write commands
