• Do not write data to the buffer memory areas (buffer memory address: 5E0H and 608H) during line test.
• Do not perform a line test using a program and other peripherals at the same time. The line test may not be normally
performed.
When performing a line test, do not set the transmission speed of slave stations to auto-tracking. Set the
transmission speed of slave stations to the same as that of the master station. An error may occur during the
line test for slave stations whose transmission speed is set only to auto-tracking. If occurred, check the cable
connection status and the network line status by following the troubleshooting procedure.
