For data storage registers, a boundary error (TermSTS = 0AH) occurs if the specified area (start register + register range) does not exist in the local port.

A response timeout error (TermSTS = 02H) occurs if the loopback response time exceeds the time specified by the timer counter value.

If the local port registers are write protected by setting the special coil, the memory write protected status (TermSTS = 04H) is returned.

e.Sample program

This sample ladder program issues a remote port loopback request to the Ethernet Port. This program is executed by turning on the R0092 A point.

A user program must compare the transmitted and loopback data for equivalence.

Parameters: 12544:3100H, 00015:000FH
