1. Features
• Excellent performance in a compact body
Succeeding the advanced functions of the FP1 programmable controller, the FP-M is designed to fulfill machine
building requirements. The advantages of compact size, expandability, and time-tested dependability are
convincing reasons to consider the FP-M as an alternative to the control systems with which you are familiar.
• Greatly increased program memory and high execution speed
FP-M surpasses the competition with a basic instruction execution speed of 1.6 µs/step and an ample program
capacity of 2,720 and 5,000 steps. The board is driven by battery-backed RAM (EEPROM or EPROM program
back-up option is also available). Types with an additional RS232C port and clock/calender (C types) are
available to boost the range of applications possible.
• Smart system expandability
Up to four expansion boards can be stacked under the control board, but no additional mounting space is needed.
This module enables you to add discrete I/O points and intelligent functions such as analog control, high-speed
counter control, and link functions easily.
Available expansion boards are:
Transistor I/O, Relay I/O, Analog I/O, A/D, D/A, High-speed Counter, I/O Link, and FP-M Transmitter Master
Boards.
I/O Expansion Example
For details about expansion refer to page 12.
* In the table above, the twenty I/O point relay type expansion board is used for the C20R and the forty I/O point
transistor type is used for the C20T and C32T.
• Easy programming environment
NPST-GR changes your personal computer into a powerful programming support tool. This editing software is
fully compatible with FP series programmable controllers.

1-1. Features and Functions
2. Functions
1) Advanced control functions
■ High-speed counter function
The built-in high-speed counter function supports four modes: two-phase input, UP, DOWN, and UP/DOWN.
The FP-M can read the input regardless of the scan time.
■ Pulse output function (transistor output type)
This function allows the output of a direct pulse (45 Hz to 4.9 k Hz) from the FP-M. In combination with a drive, a
motor can be controlled. As direct pulse is possible, an additional positioning controller is not necessary. As the
FP-M has two pulse outputs, it also supports motor drives with one input for forward driving and the other input for
reverse driving. To prevent incorrect forward/reverse driving, create an interlock circuit outside of the FP-M.
In addition, since the built-in high-speed counter can internally take the pulse output, no external wiring for feedback
control is required.
• Wiring example for a drive with one pulse input
and one direction input:
• Wiring example for a drive with two pulse inputs:

Application: Pattern output function
This function of the control board allows the setting
of a maximum of eight output patterns with 15 level
settings of the high-speed counter. Can also be
applied to multi-stage speed control with use of an
invertor.

1-1. Features and Functions
■Interrupt input function
This function executes an interrupt program immediately after an external interrupt input (minimum pulse width of
0.2 ms) occurs, regardless of the input timing. It enables high-speed processing at a fixed timing and is not affected
by scan time. Therefore it is useful when performing control which would be disrupted by variations in processing
time due to such factors as timing synchronization.
■ Pulse catch input function
■ Adjustable input time filtering function
■ Manual dial-set register control function
This function makes it possible to change the values of special data registers DT9040 and DT9041 within a range of
0 to 255 using the potentiometers on the control board. Input settings involving analog-type numerical data such as
analog timer and pulse output frequency changes can be performed.

This function allows the input response
time (input time constant) of the control
board to be changed within a range of 1
to 128 ms in accordance with the input
device connected. This prevents input
errors due to such causes as limit switch
chattering noise.
Sensor
FP-M control board
This function catches input pulse signals
down to a minimum width of 0.5 ms. It is
effective for situations such as when the
sensor detects the moving target at a
high-speed.

1-1. Features and Functions
■Forced ON/OFF control function
■Password protection function
This function forbids reading and writing of the program and system registers. It can be used for program protection
and when secrecy is required.
■Constant length scan setting function
The duration of one scan is fixed by setting it to units of 2.5 ms, eliminating variation in the scan time.
■Clock/Calendar control function (C20RC, C20TC, and C32TC types)
By means of year, month, day, hour, minute, second, and day of the week settings, this function makes it possible to
change temporal elements of control. It can be used for temporal control of such items as lighting, air conditioning,
and equipment.
This function allows the state of the input and output
contacts to be forced ON or OFF with a programming
tool (NPST-GR Software, etc.). By forcing the output
contact ON or OFF, the connection on the output side
can be checked. By forcing the input contact ON or
OFF, the program can be checked.

2) Network
■Computer link function (MEWTOCOL)
This function allows the reading and writing of FP-M contact information and data register content from a host
computer. It can be used for such applications as data collection and the monitoring of operating conditions.
The computer program is written in BASIC and C languages.
Communication between one computer and one FP-M control board
• Using programming tool port (all series)
The programming tool port can also be used for direct
connection to a personal computer.
Note:
Communication between one computer and 32 FP-M control boards
Using a C-NET adapter, a maximum of 32 FP-M control boards can be connected with one personal computer. If a
bar code reader is connected via the RS232C port, this system can be used for the collection of various production
