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. Serial Communications Unit or Serial Communications Board required.
3. ASCII Unit required.
4. 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.
5. Serial Communications Board/Unit with unit version 1.2 or later only.
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
Use
Communications between
Programming Devices and
the PLC from the computer.
Sending and receiving mes-
sages (communications
frames) according to the
communications specifica-
tions of external devices.
(SYSMAC-PST is used to
create protocols by setting
various parameters.)
Free communications with
general-purpose external
devices using BASIC com-
mands.
Converts FINS commands
that are received into Com-
poWay/F, Modbus, or Host
Link protocols, and then
transmits the converted
command to the serial line.
Converts FINS commands
(encapsulated CompoWay/F
commands) received at the
serial port into CompoWay/F
commands.
Converts FINS commands
(encapsulated Modbus com-
mands) received at the serial
port into Modbus commands.
Converts FINS commands
into FINS commands encap-
sulated in Host Link
