1. Before Using the Product
This chapter provides information you should know before using the product.
About the Module
This product is an expansio n module (device m odule) that up- counts pulse s ignals inpu t from an exter nal
device. The product is used i n combinati on 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 coun t funct ion as t he < CNT16- 8(FIT )GY > but op erate s 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 perm its a s imple, smar t system con figur ati on wi thout t he nee d for a back plane
board.

Control using the I/O address map
When connected to the CPU- SBxx (F IT) GY , th e modul e 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 ( FI T)G Y, th e mod ule 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 t he w eb. 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.

Device ID
Figure 2.1. Names of Module Components
Setting a Device ID
The controller module distinguishes and keeps track of the modules that are c onnecte d to it by ass igning
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 t hat a m a ximum of eight modules can be distinguis hed.
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.

4. Using the I/O Address Map
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 us ed 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
