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 adds digital signal I/O interfaces to one of
various types of controllers. The product is used in combination with the I/O controller module
<CPU-CAxx(FIT)GY> or microcontroller unit <CPU-SBxx(FIT)GY> in the F&eIT Series.
A single DIO-8D(FIT)GY module provides up to eight TTL-level I/O channels. (TTL 5-V type)
By reading this manual carefully, please build a system by creating applications programs, setting the
switches, and connecting the module to external devices.
Features
- The <DIO-8D(FIT)GY> can perform 8-point digital signal input and 8-point digital output, treating
8 points as a group.
- 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 a
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.

1. Before Using the Product
2DIO-8D(FIT)GY
Functions
Generic I/O functions (data I/O operations that directly access the I/O ports)
- Input
The Module reads a maximum of 8 points (<DIO-8D(FIT)GY>) of externally supplied digital signals in
groups, with each group comprising 8 points, and transmits themto a controller module that is connected
to it. Access to the Module from a controller module is performed through the input port that is specified
by means of a Device ID. When an input port is read by the execution of an input command, the buffer
gate associated with the input port is opened, and the digital signals supplied from an external device are
fetched in groups. During this operation, signals that are transmitted to the controller module will be
[High(5V): 0, Low(0V): 1].
- Output
The Module writes a maximum of 8 points (<DIO-8D(FIT)GY>) of digital signals in groups of 8 points
to an external device. Access to the Module from a controller module is performed through the output
port that is specified by means of a Device ID. When data is written to the output port by the execution
of an output command, the data is held on the latch circuit that is associated with the output port. After
being electrically isolated by an optocoupler, the digital signals are transmitted to the connected external
device through buffers.
During this operation, signals that are transmitted to the external device will be
[High(5V): 0, Low(0V): 1].
The data being held on the latch circuit remains in that state until another execution of the output
command.
Input/output switching
The Module can switch between input and output during operation. All of the eight channels are
switched. For switching using the I/O address map, set [D0] (IOSet0) at “the starting I/O address + 15h”
to “1” for input or “0” for output.
The Module can be switched during operation. Before switching the Module from input to output,
however, be sure to put the connected device into input mode.
When powered on, the Module is in the input state.
Output data monitoring function
This function allows you to keep track of the signal data that is being output.

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”.

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.

Surge Voltage Countermeasures
When connecting a load that generates surge voltages and inrush currents, such as an induction load
(relay coil) or an incandescent light bulb, is connected to the digital output, appropriate protection must
be provided in order to prevent damage to the output stage or a malfunction due to noise. The rapid
shutoff of a coil, such as in a relay, generates a sudden high-voltage pulse. If this voltage exceeds the
withstand voltage of the output transistor, it can cause the transistor to gradually deteriorate, or even
completely damage the transistor. Therefore, when driving an induction load, such as a relay coil, you
should always connect a surge-absorbing device. The following illustrates a surge voltage
countermeasure that can be employed:

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 the 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
ID No. Occupied I/O address
0 0800h - 081Fh(recommended) 0840h - 085Fh 0880h - 089Fh 08C0h - 08DFh
