DI/DO Signal Specifications

This subsection describes the specifications of the DI/DO signals used with the basic module and

expansion module.

DI (input signal specifications)

Number of points

48 points (per module)

Contact rating

30 VDC, 16 mA or more

Leakage current between

1 mA or less (26.4 V)

contacts when opened

Leakage current between

2 V or less (including a cable voltage decrease)

contacts when closed

Delay time

The receiver delay time is 2 ms (maximum).

In addition, [I/O Link transfer time between CNC and I/O module (2 ms

maximum)] + [ladder scan period (depending on CNC)] must be considered.

DO (output signal specifications)

Number of points

32 points (per module)

Maximum load current when ON

200 mA or less including momentary variations

Saturation voltage when ON

1 V (maximum) when the load current is 200 mA

Withstand voltage

24 V +20% or less including momentary variations

Leakage current when OFF

20 µA or less

Delay time

The driver delay time is 50 µs (maximum). In addition, [I/O Link transfer time

between CNC and I/O module (2 ms maximum)] + [ladder scan period

(depending on CNC)] needs to be considered.

ON/OFF of the power supply (DO common) for DO signals (output signals)

By turning off (opening) the power supply pin (DOCOM) for the DO signals (output signals), all the DO

signals of each module can be turned off at the same time. At this time, the DO state is as shown below.

DOCOM

OFF

DO state when DO is

on in the sequence

OFF

DO state when DO is

off in the sequence

OFF

NOTE

When DO is on in the sequence, the ON/OFF state of DOCOM is directly

reflected in the DO state as indicated above by the dashed box.

The +24 V signal to be supplied to the I/O module must not be turned off during

operation. Otherwise, a CNC communication alarm is issued. Ensure that +24 V

is supplied either when or before the power to the CNC is turned on, and that

+24 V is removed either when or after the power to the CNC is turned off.

Parallel DO (output signal) connection

A DO load current two times larger can be obtained by connecting DO points in parallel and exercising

ON/OFF control at the same time in the sequence as shown below. Namely, the maximum load current

per DO point is 200 mA, but 400 mA can be obtained by connecting two DO points in parallel and

turning on the two DO points at the same time. In this case, however, the leakage current is also doubled

up to 40 μA when the DO points are turned off.

NOTE

To ensure adequate ventilation within an I/O module, allow a clearance of 50

mm or more above and below the module and a clearance of 10 mm or more on

the left and right sides. Never place a device that generates a large amount of

heat below an I/O module.

To the front panel of an I/O module, the cables for the I/O Link and manual pulse

generator are connected.

For cabling, allow a clearance of about 70 mm at the front of an I/O module.

Space the basic module and expansion module at least 40 mm apart from each

other.

An I/O module is secured to the connector panel by inserting the hook into a

hole on the connector panel as with the current distribution I/O module. Allow a

clearance for hooking on the rear side of the connector panel.

For securing an I/O module, four printing prohibited areas are provided on the

surface of the connector panel, and a printing prohibited area is also provided

beside the upper and lower square holes on the rear side.

When mounting the basic module and expansion module side by side, ensure

that the basic module is mounted on the left side when viewed from the I/O Link

connector.

When inserting an I/O module into the connector panel, provide pedestals at

positions nearest to the connector of the connector panel to support the top and

bottom areas of the connector from the rear side to protect the connector panel

from being warped.

Ensure that the thickness of the connector panel printed circuit board is 1.7 mm

±0.1 mm.

DO signal reaction to a system alarm

There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link

slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the

machine to operate safely by making a safety circuit outside the I/O module.

The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is

occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned

off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.

Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

Address allocation

For the connector panel I/O module, I/O addresses are mapped as follow:

Yn + 1

Basic module

Xm + 2

Xm + 3

Xm + 12 (for 1st MPG)

Xm + 13 (for 2nd MPG)

Basic module

Xm + 14 (for 3rd MPG)

Xm + 15 (for DO alarm

detection)

Each of Xm and Yn represents the start address of the module on the I/O Link.

Basically, I/O module type-2 is allocated a group of DI addresses (16 bytes) and a group of DO addresses

(8 bytes). Add or remove expansion module hardware as required. The reason is explained below.

The MPG interface (MPG counter) occupies a DI space from Xm+12 to Xm+14. These addresses are

fixed regardless of whether an expansion module is used, and Xm+12 to Xm+14 must be allocated as a

DI work area to enable the use of an MPG. Therefore, when using an MPG, allocate DI addresses in units

of 16-byte groups. The CNC directly processes the value of the MPG counter. So, ensure that the ladder

does not use this area.

DI address Xm+15 is used to detect an overheating alarm issued for a cause such as overcurrent of the IC

used for a DO driver. Address Xm+15 is fixed regardless of whether an expansion module is used. This

address must be allocated as a work area before this address can be used.

For the reason mentioned above, allocate DI addresses for I/O module type-2 in units of 16-byte groups.

DO (output signal) alarm detection

The DO driver of the basic module and expansion module A/B has a function for detecting a load

overcurrent and its temperature. If an accident such as the connecting of the cable to ground causes an

abnormal increase in the load current or in the DO driver temperature, a protection circuit, which is

provided for each DO driver (1 byte), is activated and keeps the 1-byte DO signal in the OFF state until

the cause of the problem is eliminated. Even in this case, the CNC and I/O module continue operation

with no alarm issued. However, the DI address (Xm+15) identifies the DO driver that has detected the

alarm. The table below indicates the correspondence between the DI address (Xm+15) bits and the DO

addresses. Bit value "1" of the DI address (Xm+15) indicates that the corresponding DO driver has

detected an alarm. If a DO alarm is issued, troubleshooting and recovery can be enhanced by checking the

contents of the Xm+15 area with the DGN screen of the CNC or by performing Xm+15 alarm processing

in advance with the ladder.

If the number of DI/DO points is not sufficient, external I/O units such as the dispersed I/O can be added

using the FANUC I/O Link.

A MIL-compatible ribbon cable connector is used as the interface connector of the I/O unit for 0i to

simplify connection to the connector panel.

The connector can also be used for the Series 0i Mate.

DO signal reaction to a system alarm

There is a possibility that the I/O unit will not operate normally due to a failure of CNC or I/O Link slave

module, or abnormally power supply voltage. To prevent accidents even in this case, design the machine

to operate safely by making a safety circuit outside the I/O unit.

in the CNC which controls the I/O unit, or if a power of the CNC or the I/O unit is turned off. However, it

cannot be guaranteed that DO signals of the I/O unit will certainly be turned off. Therefore, manage

signals related to safety by making a safety circuit outside this I/O unit.

DO (output signal) alarm detection

The DO driver of the I/O unit for 0i is capable of detecting an overcurrent and measuring its own

temperature. If an accident, such as the connecting of the cable to ground, causes an abnormal increase in

the load current or in the driver temperature, a protection circuit, which is provided for each DO driver (1

byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the

problem is eliminated. Even if this occurs, the CNC and I/O module continue operating. The DI address

(Xm+15) identifies the DO driver which has detected the alarm. The following table shows the

correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value "1" indicates that

the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by

using the DGN screen of the CNC or by performing alarm processing for the area in advance by using

Ladder. This helps alarm detection and recovery.

Cautions

The following cautions must be observed when using I/O signal receivers and drivers for the machine

interface.

DI Signals and Receivers

DI signals are basically of the sink type (a type that drains energy). Some DI signals, however, can be

set to either sink type or source type (a type that supplies energy). See the description of the I/O board

in the following section for details.

A common signal is provided for selectable receivers. Whether the common signal is connected to 0 V

or 24 V determines whether a DI signal is of sink or source type.

A source type DI signal is undesirable from the viewpoint of safety, however, because if the input signal

line is grounded, it will be latched in the same state as that existing when the contact is closed. It is

recommended that all DI signals be set to sink type.

Always connect the common signal to either 0 or 24 V; do not leave it open.

DO Signals and Drivers

The driver of DO signals is source type (a type that supplies energy, non-insulating).

There is a possibility that the I/O unit will not operate normally due to a failure of CNC or I/O Link slave

module, or abnormally power supply voltage. To prevent accidents even in this case, design the machine

to operate safely by making a safety circuit outside the I/O unit.

The circuit of this I/O unit is designed so that all DO signals are turned off if a system alarm is occurred

in the CNC which controls the I/O unit, or if a power of the CNC or the I/O unit is turned off. However, it

cannot be guaranteed that DO signals of the I/O unit will certainly be turned off. Therefore, manage

signals related to safety by making a safety circuit outside this I/O unit.

NOTE

Output signal driver

Each of the output signal driver devices used on this I/O board outputs eight

signals.

A driver device monitors the current of each output signal. If it detects an

overcurrent on an output, it turns off the output. Once an overcurrent causes

an output to turn off, the overcurrent is no longer present. Then, the output is

turned on again. In ground-fault or overload conditions, outputs may turn on

and off alternately. This phenomenon also occurs when a load with a high

surge current is connected.

Each driver device contains an overheat detector circuit. If an overcurrent is

observed on an output continuously because of a ground-fault or similar reason

and the temperature in the device rises, the overheat detector circuit turns off all

eight outputs. The output-off state is maintained. This state can be released

by logically turning off then on again the outputs after the internal temperature of

the device drops to a specified level. This state can also be released by turning

off the system power supply.

The output signals of the driver devices are assigned the following addresses:

Device #0: Yn+0.0 to Yn+0.7

Device #1: Yn+1.0 to Yn+1.7

Device #2: Yn+2.0 to Yn+2.7

Device #3: Yn+3.0 to Yn+3.7

Device #4: Yn+4.0 to Yn+4.7

Device #5: Yn+5.0 to Yn+5.7

Device #6: Yn+6.0 to Yn+6.7

Device #7: Yn+7.0 to Yn+7.7

If NC diagnosis shows that an output is on but the output is actually not turned

on, an overload on that output or another output in the same device may have

turned off the eight outputs of that device. In such a case, turn off the system

power supply and remove the cause of the overload.
