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.

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

4. Using the I/O Address Map

Bit Assignments for I/O Ports

The I/O ports for the counting function have command-section and data-section registers.
A register can be set as follows: First, a command is issued (OUT) to a port located at starting I/O

address + 16 to make the register available for setting. For output, data is assigned (OUT) to the register
at port +17; for input, the +17 port is read. In other words, for both input and output, a command is
issued (OUT) to the output port +16 to make registers available for setting, and either data is issued
(OUT) to the port +17 to set the register or the register is read at the +17 port.

When setting a register even when using the same command, the command should be output to the
output port +16 each time.

Figures 4.8. and 4.9. show I/O port bit assignments.

Description of Input Commands

Reading a Count (command 00h - 07h)

By reading the contents of the R EA D regi ste r fo r a co rres pon ding c hann e l, th is co mman d reads a co unt
value. By issuing the command to the output port +16 and reading the input port +17 two times, you ca n
read low, middle, and high count values.

In the initial state, the contents of the READ register are undefined.
Following are programs that read a count value from CH0:
Microsoft C

outp( ADR+16, 0x0 ); OUT ADR+16, &H0
LowerData = inp( ADR+17 ); LowerData = INP( ADR+17 )
UpperData = inp( ADR+17 ); UpperData = INP( ADR+17 )

In this case, the count value latch for CH0 must be pre-set to [1].

Interrupt mask (command 11h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

This command allows you to monitor the status of the current interrupt mas k tha t wa s se t us ing the
interrupt mask command. CH7 - CH0 are associated with channels. When these bits are [1], the interrupt
is masked, and no interrupt signals are output.

You can monitor the masking status by issuing the value 15h to the output port +16 and by reading the
input port +17.

Initial state: FFH

Status (command 12h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

12h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Status 8-bit

Indicates a carry-up occurred for the count on each channel.
By issuing 12H to the output po rt +16 and re ading th e inp ut po rt +17 , you can monito r the status . Th e

corresponding bit is set to "1" when a carry-up occurs on a channel (CH7 - CH0).

0 : No carry
1 : Carry

CAUTION

- Initial state: 00h

- If an interrupt is generated with the interrupt option set, and if one of the bits in CH7 - CH0 is set to
[1], before another interrupt can be generated, the affected sense bit must be reset. For a description
of how to reset a sense bit, see "Sense Reset" on output ports.

Count control (Command 14h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

14h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Count control 8-bit

Count operating status of each channel is displayed.
You can monitor the operaing status by issuing the value 14h to the output port +16 and by reading the

input port +17.

4. Using the I/O Address Map

Description of Output Commands

Initial Count Value (command 00h - 07h)

The command is issued to the output port +16, and an initial count value is set on the output port +17.
Because count data consists o f 16 bits, count values ar e outp ut tw o tim es in l ow, m iddle, and high order ,
8 bits each time. When the third (high 8 bits) count value is output, data consisting of 16 bits is loaded
simultaneously by the counting process.

Following are program examples that set a count value 100(64h) on CH0:
Microsoft C

outp( ADR+16, 0x0 ); OUT ADR+16, &H0
outp( ADR+17, 0x64 ); OUT ADR+17, &H64
outp( ADR+17, 0x0 ); OUT ADR+17, &H0

Count Data Latching (command 10h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

10h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Count data

This command latches a count value on a corresponding channel to the READ register.
The command issues the value "10h" to the output port +16, and set s a dat a latch on th e outp ut port + 17.
These bits are associated with the respective channels. The command latches the count value by setting the

applicable bit to "1". All channels can be latched simultaneously by setting all applicable bits to "1".

The initial condition is no-latch (00h).

Interrupt Mask (command 11h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

11h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Interrupt Mask 8-bit

This command issues the value "11 h" to the output p ort +16, and set s a mask on the ou tput port +17. The
generation of interrupt signals is disabled when an applicable bit is set to "1".

These bits are associated with the respective channels. Setti ng the val ue "1" to any of these bits disable s a
carry-up interrupt on the associated channel. Setting the value "0" resets the disabled condition.

CAUTION

- In the initial condition, all channels are timer-masked (FFh).

- Even in the masked state, on all channels the carry-up conditions change.

Status Reset (command 12h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

12h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Status Reset 8-bit

The interrupt sense sets an applicable bit to "1" when carry-up condition is detected on a given channel.
When the applicable bit is "1", an interrupt signal is not generated when another carry-up condition

arises. Issuing the value "+12h" to the output port +16 and the value "1" to the applicable bit on the
output port +17 clears the sense bit, and enables the generation of another interrupt signal.

13h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Counter

initialization

8-bit

This command resets the counter data of each channel to 0000h.
The command issues the value "13h" to the output port +16, and resets on the output port +17 and sets

the applicable bit to "1".

Counter control (command 14h)

Command D7 D6 D5 D4 D3 D2 D1 D0 Function Data length

14h CH7 CH6 CH5 CH4 CH3 CH2 CH1 CH0 Counter control 8-bit

This command controls the corresponding count operation of channel. The command issues the value
"14h" to the output port +1 6, and sets a c ount c ontr ol on t he o utput por t +17. T he c ommand c ontr ols t he
count operation by setting the applicable bit to "1".

These bits are associated with the respective channels. Setti ng the value "1" to any of these bits starts counting.
Setting the value "0" to any of these bits stops counting.

CAUTION

- The initial state is all channels stopped(00h).

- The count data remains unchanged while the count is stopped.

Digital Filter (command 15h)

Using this function digitally filters the signals at all input pins by means of hardware. Use it to prevent
input signal noise and chattering from being detected by mistake.

The level is checked at each clock sampling time. If the signal le vel remains the same for longer tha n the
time set for the digital filter, the signal is treated as a vali d input and the level of the P C signal is changed.

Accordingly, if leve l changes occur at a higher frequency than the filter time, the level changes will not
be detected.

5. Using the Memory Address Map

When connected to a CPU-CAxx(FIT)GY, the CNT16-8(FIT)GY, CNT16-8L(FIT)GY can be accessed
by a host computer through a network. In addition, the Module can be allocated to the memory
controlled by the Controller Module according to a given Device ID. Applications running on the host
computer control the I/O modules by reading/writing the memory that is controlled by the Controller
Module.

For detailed specifications on the memory controlled by the Controller Module, see the Controller
Module manual.

Following is an explanation of the memory areas necessary for the use of this I/O module: the "module
area", the "module information area", and the "basic data area".

Module Information area
This area controls the settings and how the module is started.
The module becomes available when the necessary settings are written into this area and the module

activation option is set in the [module startup register].

Module information area
The current module settings are stored in this area.
When the Module is star ted , th e cont en ts of th e Module Information Area are copied to the Module

Information Area. By reading this area, you can verify the current module settings.

Basic I/O data area
Basic I/O data is accessed in this area.

5. Using the Memory Address Map

Channel settings

- Startup register
This command controls the corresponding count operation of the channel. The command controls

the count operation by setting the data of corresponding ch annel to 01h .
Setting "01h" to the setting for each channel starts counting on that channel. Setting "00h" stops

counting.
00h : Stop

01h : Start
Setting the module start setting (01h) to the module startup register sets the startup registers for all

channels to "01h".

CAUTION

The count data does not change while the count is stopped.

- Status reset
When a carry-up occurs on a channel count, the data for the corresponding channel in "module data

area", "channel data", and "status" goes to "01h".
The next carry-up does not occur if the "status" for a channel is "01h". Using status reset to output

"01" to the corresponding channel clears the sense and permits the next count carry-up to occur.
00h : No operation

01h : Sense reset
Changes to "00h" when sense reset processing completes.

- Counter initialization
Resets the counter data of each channel to 0000h.
00h : No operation

01h : Counter initialization

Changes to "00h" when counter initialization completes.

- Preset counter value
By setting values, you can set a preset value to the count for each channel.

The preset counter value is stored as a little endian value.

When the module is started, the contents of the module information area are stored in the module
information area.

Items common to mo d u les

- Module startup register
This register stores the module operating status.

00h : No operation

01h : Module startup

- Error status
This register stores the error status of the module.

The error status register is reset when the module is restarted.

00h : Normal status

5. Using the Memory Address Map

- Counter resolution
This can be used to check the counter resolution for the CNT16-8x(FIT)GY.

- Digital filter setting
This can be used to check the digital filter setting.

Channel settings

- Startup register
This register displays the count operating status of each channel.
00h : Stopping
01h : Operating

- Status
Indicates a carry-up occurred for the count on each channel. The data corresponding to each channel

is set to "01h" when a ca rry -up oc cu rs on a ch an nel .
00h : No carry
01h : Carry
Once a carry-up has occurred for a channel, the next carry-up cannot be detected until the sense is

reset for that channel. See “Status reset” in the “ module in formation area” for detai ls of sense reset.
