Expanded System Configuration Section 2-5
Note 1. The Peripheral Bus Mode is used for Programming Devices excluding Pro-
gramming Console. If Programming Console is to be used, set pin 4 of the
DIP switch on the front panel of the Unit to OFF so that the default periph-
eral port communications parameters are used instead of those specified
in the PLC Setup.
2. CPU Unit with version 3.0 or later (peripheral port and RS-232C port) and
Serial Communications Board/Unit with unit version 1.2 or later only.
3. Serial Communications Board/Unit with unit version 1.2 or later only.
Host Link System
(SYSMAC WAY Mode 1:N)
The Host Link System allows the I/O memory of the PLC to be read/written,
and the operating mode to be changed from a Host computer (personal com-
puter or Programmable Terminal) by executing Host Link commands or FINS
commands that are preceded by a header and followed by a terminator. Alter-
natively, FINS commands (preceded by a header and followed by a termina-
tor) can be sent to a computer connected via the Host Link System by
executing Network Communications Instructions (SEND(090)/RECV(098)/
CMND(490)) from the PLC.
