The CPU of the FP2/FP2SH includes a COM (RS232C) port and TOOL (RS232C)
port as standard equipment, making it possible to connect a MODEM to perform pro-
gramming and computer linking from a remote location using a public telephone line.
When the power supply of FP2/FP2SH is turned on, it will verify whether a MODEM is
connected, and, if a MODEM is, it will automatically transmit the AT command to set the
MODEM for automatic reception.
Since the reading and writing of the relay conditions and register contents of the pro-
grammable controller can be performed from the host computer, this function is
applicable for remote monitoring systems.
When using the TOOL port, you can use programming tool software (NPST-GR/FPWIN
GR) and perform reading and writing of the programmable controller program and main-
tenance operations via MODEM.
During 1:1 communication using the COM port, an error alarm can be issued from the
programmable controller.
1:N communication
Using the C-NET adapter enables MODEMs to be
connected for multiple programmable controller.
