9.11.4 Installation
Notes on installation
1) Use a module in a completely sealed cabinet.
2) Be sure to install a module on a vertical plane and allow a clearance of 100 mm or more above and
below the module. Do not place a device that generates a large amount of heat below the module.

Using a DIN rail for mounting
1) Method of mounting
DIN rail
Locking section
1)
Place the hook of the module onto the top of the DIN rail.
2)
Push the module until it clicks into place.
NOTE
Ensure that the locking section is not left lowered.
2) Method of dismounting
DIN rail
1)
Lower the locking section with a flat-blade screwdriver.
2)
Pull the lower part of the module toward you.
NOTE
When dismounting the module, be careful not to damage the locking section by
applying an excessive force.

Recommended cable (for using external power): A02B-0124-K830
(5 m long, with an M3 terminal on the 24 V power supply side)
The 24 VDC input to CP11A (A1, A2) can be output from CP11B (B1, B2) for branching. CP11B (B1,
B2) is connected as shown below. In this case, the external 24 VDC power supply needs to provide
CP11A (A1, A2) with a current which is equal to the sum of the current consumed by the control unit and
the current used via CP11B (B1, B2).

The maximum DC output supplied by the CP11B is 2 A.
NOTE
1 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.
2 When turning off the power to the CNC control unit, be sure to turn off the power
to the terminal type I/O module and other slave I/O units connected via the I/O
Link as well.

DO alarm detection
(This address is not used with
expansion module C.)
Basically, the module is allocated a group of DI addresses (16 bytes) and a group of DO addresses (8
bytes). Add or remove up to three expansion modules by 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 expansion module 2 or 3 is used, and Xm+12 to Xm+14 must be allocated as
a DI work area to enable the use of the MPG. Therefore, when using an MPG with the i series, 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. (For details, see Subsection 9.11.6.2, "DO alarm detection".) Address Xm+15 is
fixed regardless of whether expansion module 2 or 3 is used. This address must be allocated as a work
area before this address can be used. When using this area, therefore, allocate DI addresses in units of
16-byte groups.
Addresses of expansion module C
Expansion module C is a module with 16 points for output only but can be allocated in any space of
expansion module 1, 2, or 3. With this module, DO alarm information (2 bytes/module, with DO alarm
information provided for each DO point), which is described later, is allocated to the DI area. For the
relationship between DO bits and DO alarm information, see "Expansion module C" in Subsection
9.11.6.2.
Addresses of expansion module D
<Digital output>
Expansion module D has four analog input channels and has only one 12-bit digital output channel in the
3-byte DI area. The DI format is as indicated below. The digital output addresses start at the first
even-numbered address in the 3-byte area. (See the next page.)

D00 to D11 represent 12-bit digital output data (represented as a complement). D00 corresponds to the

9.11.6.2 DO alarm detection
Basic module, expansion modules A and B
The DO driver 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.

Expansion module C
The DO driver of expansion module C has not only the overheat protection function (overcurrent
detection and temperature detection) as available with the basic module and expansion modules A and B
but also an over voltage protection function and disconnection detection function, and a DO bit is
allocated to each protection circuit.
When any of these functions is activated, the bit corresponding to the LED "ALARM" of the module is
turned on. The CNC continues operation with no alarm issued. However, the DI address area identifies
which DO driver has detected an alarm. The next page indicates the correspondence between the DI
address bits and the DO address bits.

NOTE
1 If the overheat protection function or over voltage protection function among the
protection functions above is activated, the DO bit is kept OFF until the cause is
eliminated. When the cause is eliminated, the DO bit is set to ON without
restarting the system.
2 Disconnection detection is performed by monitoring, with an output element in
the module, the current flowing through a load when DO output is ON. When the
detected current value is about 100 mA or less, disconnection detection is
assumed. So, when a device (such as an LED) with a small load current is
connected, the DO alarm state results, assuming disconnection detection. Unlike
the other protection functions, however, this function does not turn off DO output.
If a connection is reactivated after the state of disconnection is once set,
disconnection detection is canceled without restarting the system.

9.11.7.2 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.

9.11.7.3 Parallel DO (output signal) connection
Basic module, expansion modules A and B
With the basic module and expansion modules A and B, 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 that the bits that can be set to ON/OFF at the same time must belong to the same address. (For
example, bits at address Yn+3 may be set to ON/OFF at the same time.)
