operation using the actual device. In some cases, the number of units, transmission distance,
and baud rate vary depending on the connected device.
Note3)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.
Note4)The number of units of the PLC link with RS232C/RS422 is two.
Note5) When setting to 230400 bps, use USB ports at computers. If connecting to RS232C ports, a
device open error occurs and communication is not available.
