8-12. Modem Communication

FP-M programmable controllers have modem communication functions.
This allows data transfer and long-distance communication between a personal computer and an FP-M.
This function is available not only for the computer link function but also when NPST-GR Software is used.
Using C-NET adapters, you can control up to 32 programmable controllers with one computer.

1. Using the Programming Tool Port (FP-M control board all types)

When modem communication is performed using the programming tool port of an FP-M, not only computer link but
also programming with NPST-GR Software can be performed.
To perform modem communication using the programming tool port, set system registers 410 and 411 as follows:
- System register 410......Station number setting
- System register 411......Communication format and modem setting
Notes:
• With NPST-GR Software version 3.0 or higher, you cannot set system register 411 to the modem enable
mode.
• The baud rate is fixed at 2,400 bps and the setting in system register 414 is ignored.
• The same station number (UNIT NO.) cannot be assigned to FP-Ms in the same network.
• Since initialization of the modem is performed only by a FP-M whose UNIT NO. (system register 410) is
set to K1, pay attention to the following when station numbers (UNIT NO.s) are assigned to FP-Ms:
- when one computer communicates with one FP-M, system register 410 should be set to K1.
- when one computer communicates with two or more FP-Ms, no two FP-Ms can have the same station
number (UNIT NO.) and one of the FP-Ms in the network must be assigned as station number 1
(UNIT NO. 1).
• Modem initialization is performed only when the mode of the programmable controller is set from PROG.
to RUN or when the power turns ON in the RUN mode by an FP-M whose UNIT NO. (system register
410) is set to K1. Therefore, be sure to apply power to the modem, before the FP-M is turned ON.
• Once the modem is initialized successfully, it will not re-initialize if the mode of the programmable
controller is set to RUN from PROG. again.
• When one computer communicates with two or more programmable controllers, set the modem to the
mode without character echo.
• Be sure to set the computer and C-NET adapters to the same communication format.
