For data storage registers, a boundary error occurs if the specified area (start register + register range) does not exist in either the local or remote ports.

Local port: TermSTS = 0AH, remote port: TermSTS = 8AH

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

Read protection can be specified for each register type on the local T2N by using the special coil settings described below. In this case, a memory write protect error (TermSTS = 04H) will occur.

When PC link transmission or the UDP socket interface is used, if an application transmits to a nonexistent remote port, an transmission error (TermSTS = 0BH, detailed information = 0020H) occurs.
