When sending a command to a PLC-5 from a PLC-3, use the following
guidelines to program the message instruction.
The PLC-3 has six levels of addressing while the PLC-5 has only four
levels. Therefore, if a PLC-5 received a full PLC-3 six-level address, it
would return an error code. The following table summarizes the addressing
levels of the PLC-3 and PLC-5.

To communicate from the PLC-3 to the PLC-5, you must enter the PLC-5
address in the following format:
$ E [Major Section].[File #]. [Element].[Sub-Element]
A command of this format can be accepted by the PLC-5 because the
address has only 4 levels.
