CS/CJ/NSJ Series Instructions Reference Manual (W474)
Note 1 The following two methods can be used to send data to the host computer through a serial port with the host link
while initiating communications from the PLC.
1) Set the destination unit address (bits 00 to 07 of C+2) to the unit address of the CPU Unit or Serial Communica-
tions Unit/Board and set the serial port number (bits 08 to 11 of C+1) to 1 for port 1 or 2 for port 2.
2) Set the destination unit address directly into bits 00 to 07 of C+2. In this case, set the serial port number in bits 08
to 11 of C+1 to 0 for direct specification.
• Serial Communication Unit ports
• Serial Communication Board ports
• CPU Unit ports
2 When specifying the serial port without a routing table for the serial gateway function (conversion to host link FINS),
set the serial port's unit address in the destination network address byte.
3 Set the destination network address to 00 to transmit within the local network. When two or more CPU Bus Units are
mounted, the network address will be the unit number of the Unit with the lowest unit number.
4 For a broadcast transmission, set #FF hex.
To send within the same node, set #00 hex.
