6.1 PLC Link
The PLC link enables read data to be directly stored in the internal memory of a
PLC (programmable logic controller).
Since the N-400 directly controls the PLC’s memory, no program is required for
data communication, resulting in a reduced number of programming steps.
As compared with the serial communication using a computer, the PLC link in-
volves the following limitations:
• The settings of the N-400 and BL series cannot be changed on the PLC.
• The PLC link cannot send a command to the BL series. However, the PLC link
provides a reading control address to start/end reading.
• The PLC link cannot send a command to the N-400. The start of auto polling or
registration of ID numbers cannot be set on the PLC.
To register ID numbers, use the N-400 setup software.
