-

10

•

•

The number of bytes to read:

- is an odd number.

- equals zero.

- is greater than the maximum allowed in a reply

packet (244).

•

The sum of packet offset and size of data in words

is greater than 65,535.

•

The sum of packet offset and size of data in words

is greater than the total transaction size.

-

30

The local PLCĆ3 interface module has executed a

-

40

A backplane error (memory parity, timeout, or

required.

•
