1. Before Using the Product
This chapter provides information you should know before using the product.
About the Module
This product is an expansion module (device module) that up-counts pulse signals input from an external
device. The product is used in combination with the I/O controller module < CPU-CAxx(FIT)GY > (*1)
or microcontroller unit < CPU-SBxx(FIT)GY > (*1) in the F&eIT Series.
Each < CNT16-8(FIT)GY > module can count a maximum of eight pulse signals. The pulse signals are
input via opto-couplers. The external power supply can be in the range 12 - 24 VDC.
The < CNT16-8L(FIT)GY > has the same count function as the < CNT16-8(FIT)GY > but operates on a
5 VDC external power supply.
Please read this manual carefully to create application programs and configure the system, such as
setting the switches and connecting it to external devices.
*1 The "x" in a model code represents a single digit (or no digit) indicating different products. (The
same convention applies below).
Features
- Performs a 16-bit up-count for eight channels.
- Isolated from each other by an opto-coupler, offering good noise immunity.
- A digital filter is included to prevent miscounting due to chattering on the input pulses.
- A rotary switch allows you to set device IDs to help you keep track of device numbers.
- Like other F&eIT series products, the module has a 35mm DIN rail mounting mechanism as
standard. A connection to a controller module can be effected on a lateral, stack basis in a unique
configuration, which permits a simple, smart system configuration without the need for a backplane
board.

* The API-SBP(W32) is included in the development kit [DTK-SBxx(FIT)GY]; the other drivers are bundled with each
controller.
Control using the I/O address map
When connected to the CPU-SBxx(FIT)GY, the module can receive I/O instructions directly from the
controller module. For details, see Chapter 4 “Using the I/O Address Map”.
Control using the memory address map
When connected to the CPU-CAxx(FIT)GY, the module can be accessed from the host computer over
the network. The module is assigned with its device ID in the memory managed by the controller
module. The application running on the host computer controls the module by reading/writing the
memory managed by the controller module. For details, see Chapter 5 “Using the Memory Address
Map”.
Control via the Windows driver
For the functions and settings available when using the Windows driver, refer to the reference manual
and online help for each module.
Control over the web
You can monitor collected data and manage the log over the web. You can use your familiar browser to
easily make various settings. For details, refer to the reference manual for the SVR-MMF2(FIT),
SVR-MMF(FIT)GY.

Figure 2.1. Names of Module Components
Setting a Device ID
The controller module distinguishes and keeps track of the modules that are connected to it by assigning
device IDs to them. Each module, therefore, should be assigned a unique ID.
A Device ID can be assigned in a 0 - 7 range, so that a maximum of eight modules can be distinguished.
The factory setting for the Device ID is [0].
Setup Method
A Device ID can be set by turning the rotary switch that is located on the module face.
A Device ID can be assigned by turning the switch.

External I/O Circuits
Input section
Figure 3.3 or 3.4 shows the input equivalent circuit for the interface section.
The signal input section consists of an opto-isolated input (compatible with both current sink output and
current source output). An external power supply is therefore required to drive the input section of this
module. The power requirement for the < CNT16-8(FIT)GY > is about 8 mA per input channel at
24 VDC (about 4 mA at 12 VDC) and for the < CNT16-8L(FIT)GY > is about 4 mA per input channel at
5 VDC.

4. Using the I/O Address Map
CNT16-8(FIT)GY, CNT16-8L(FIT)GY 15
4. Using the I/O Address Map
Starting I/O Address
When connected to a CPU-SBxx(FIT)GY, the Module can directly receive I/O commands from the
controller module. Depending on how the Device ID is set, the I/O addresses indicated below will be
used exclusively by the Module.
Because the address bus on which I/O address space is allocated is not fully decoded in 16 bits, four
starting I/O addresses exist for each Device ID.
If the Device ID is set to 0h, one of the four addresses (0800h, 0840h, 0880h, or 08C0h) will be used as
a starting I/O address.
Table 4.1. List of Starting I/O Addresses
< CNT16-8(FIT)GY, CNT16-8L(FIT)GY >
ID No. Occupied I/O address
0 0800h - 081Fh(recommended) 0840h - 085Fh 0880h - 089Fh 08C0h - 08DFh

For detailed specifications on the I/O space that is managed by the controller module, see the controller
module manual.
