» Push the limits of serial technology: baud rates up to 230.4 kbps, distance up to

1200 m, and multiple block batch read/write up to 960 words from QCPU device memory.

» External devices (personal computer, HMI, etc.) may read and write data in the

programmable controller CPU using MC protocol.

» Connect with intelligent devices using their native protocol (barcode reader,measurement device, etc.) by selecting non-procedure protocol and using a sequence program for communication control.

» MELSOFT engineering tools can establish a connection to the programmable controller CPU through the serial connection to perform programing and maintenance duties.

» Dedicated functions are available to facilitate RS-232 communication over public

telephone lines using a serial modem. One of them, the remote password function, prevents unauthorized access to programmable controllers via the modem line.
