Note2) The values for the transmission distance, baud rate and number of units should be
within the values noted in the graph below.
When using a baud rate of 2400 bps to 38400 bps, you can set up to a maximum of
99 units (stations) and maximum transmission distance of 1200 m.
Note3) Only 9600 bps or 19200 bps can be specified when the C-NET adapter is connected with the
RS485 interface.
Note4) The start code and end code can be used only in the general-purpose serial communication
mode.
Note5) The converter SI-35 manufactured by Lineeye Co., Ltd is recommendable for the RS485 at the
computer side. Adjust the response time for the FP-X by the SYS1 instruction if necessary.
Note6)Regarding the setting of unit numbers:
When the unit number setting switch is "0", the system register is effective.
When the unit number setting switch is other than "0", the unit number setting switch is effective,
and the unit number setting of the system register is ignored.
(Max. 31 units can be specified with the unit number setting switch.) (When the setting is specified
with the unit number setting switch, the COM port 1 and the COM port 2 has the same unit
number.
Note7)Connect the "−" terminal and the "+" terminal with a lead wire to make the termination resistance
of the AFPG803 effective.
The termination resistance of the AFPG806 is specified by the dip switch in the communication
cassette.
There is no termination resistance at the RS232C port.
Note8) The RS485 port of the AFPG806 is either 19200 bps or 115200 bps only.
Also the baud rate must be identically set by the system register and the dip switch in the
communication cassette. The baud rate for the PC(PLC) link mode is fixed at 115200 bps.
The baud rate for the RS232C port of the AFPG806 can be set by the system register only.
Note9) The MEWTOCOL master function, MODBUS RTU master function and general-purpose serial
communication function at the TOOL port is available only for the FPΣ 32k type.
