what you ordered.
■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
■ESI FILES
ESI files are downloadable at our web site.
POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVE
• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
24V DC rating: 24V ±10%, approx. 55mA
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power
supply, input signal, and output signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

EtherCAT SPECIFICATIONS
■Modular Device Prole
R7I4DECT-1-DC32A complies with the Modular Device Profile (MDP) standard, ETG.5001.1 of the EtherCAT standard.
Be sure that the master supports the MDP standard.
■Fixed address
R7I4DECT supports Explicit Device Identification by allowing setting of fixed address using the fixed address setting rotary
switches (ID selector).
The fixed address can be set to be 1 to 255.
When fixed address is not used, set the ID selector to 0.
When the power is turned on with the ID selector set to other than 0, the designated address is written in the resistor 0x0012
of ESC (EtherCAT Slave Controller) when R7I4DECT starts up.
■Initialization
At the start up, objects of the process data mapping (RxPDO, TxPDO) corresponding to the I/O data of the device, and the
other objects are created in the object dictionary.
After initialization, the master unit is available to require to the slave unit (R7I4DECT-1-DC32A) to switch the status from
INIT to PREOP.
If the initialization is not completed due to any error with the module, switching requirement is rejected with AL status code
at switching from INIT to PREOP.
■Data Conguration
Data are configured in accordance with the EtherCAT Modular Device Profile (MDP) specifications as shown below.
Table 1: Data Conguration

Input Area Objects 0x6001 Input data, Output status data
Output Area Objects 0x7000 Output data

Identity Objects 0x1018 Vendor information
■EtherCAT State
EtherCAT defines four states of slave: INIT, PREOP, SAFEOP, and OP.
TxPDO (input configuration data) is updated only in the SAFEOP or OP state, and RxPDO (output configuration data) is
updated only in the OP state.
The RUN LED turns on only in the OP state and input and output data are updated.

■EtherCAT Diagnostics
• AL Status Code
When the slave (R7I4DECT) fails to receive a request from the master or when there is a problem with the slave during nor-
mal communication, an error code is set to registers 0x0134 and 0x0135 (AL Status Code) of ESC.
The error codes that R7I4DECT uses are as shown below.
Table 2: Error Codes of AL Status Code
CODE ERROR
0x0000 No error
0x0011 Invalid requested state change
0x0012 Unknown requested state
0x0013 BOOT state not supported
0x0016 Invalid MailBox configuration (PREOP)
0x0017 Invalid SyncManager configuration
0x001B SyncManager Watchdog Timeout
0x001D Invalid Output Configuration
0x001E Invalid Input Configuration
0x001F Invalid Watchdog Configuration
0x0029 FreeRun needs 3 Buffer mode
• SDO Abort Code
When the master attempts to access the object dictionary via SDO, if the slave (R7I4DECT) fails to receive SDO messages for
any reason, R7I4DECT sends an error code (SDO Abort Code) to the master and denies its access.
The following error codes are used.
Table 3: Error Codes of SDO Abort Code
CODE ERROR
0x05030000 Toggle bit not changed
0x05040001 Client/Server command specifier not valid or unknown

■STATUS (Input Area Object)
When overcurrent or overheat is detected on each channel of discrete output while the output is ON, the status bit correspond-
ing to the output turns “1” and is latched*. Then the discrete output is also latched to OFF.
To reset the latched bit and discrete output, set this output to OFF from the host PC/PLC or turn off and on the power supply
to the unit.
When disconnection (open load) is detected while output is OFF, the corresponding status bit turns “1” but is not latched.
* The status bit turns “0” if the load is opened in the state overcurrent or overheat is detected. However, the discrete output of the
unit remains latched. Be sure to remove the cause of error and reset the latched output by setting the output to OFF or turning
off/on the power supply.
