POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• The equipment must be mounted inside a panel.
• 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 con-
formity.
* For example, installation of noise filters and clamp fil-
ters for the power source, input and output connected
to the unit, etc.
■GENERAL PRECAUTIONS
• Before you remove or mount the unit, turn off the power
supply for safety.
• DO NOT set the switches on the module while the power
is supplied. The switches are used only for maintenance
without the power.
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
DC Power supply: 24V DC rating
24V DC ± 10%, approx. 12W
(@ internal power max. current 1.6A)
Excitation supply (excitation for I/O module):
24V DC ± 10%, operational current 10A
(From power supply (excitation supply) connector, via
connector for internal bus, supplied to each I/O module.
Power output current consumption must be under opera-
tional current.)
■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 Prole
R8-NECT1 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
R8-NECT1 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 R8-NECT1 starts up.

■Initialization
When the R8-NECT1 boots up, the process data is configured according to the configuration of connected I/O card. Then the
object of process data mapping (RxPDO, TxPDO) corresponding to the I/O data of devices and the object of various information
for R8 are created in the object dictionary. The configuration of process data is fixed at the time only when the R8-NECT1
boots up.
It takes about 3 seconds to initialize the R8-NECT1. After initialization, master can make a demand to slave (R8-NECT1) to
switch from INIT state to PREOP state. If initialization is failed with some abnormality of R8, it is denied by using AL status
code when transition from INIT to PREOP.
■Process Data Conguration
After boot up, the R8-NECT1 identifies all connected I/O cards. Set the address for each I/O cards in advance. For analog 4
points input card and analog 4 points output card, two addresses are allocated to one module (selected address and next ad-
dress). Also there are modules which allocate four addresses, eight addresses.
R8 configures process data by module, as ‘1 address = 1 module’. One R8-NECT1 can manage max. 32 modules. However,
max. number of connectable I/O module is 16.
All I/O modules and its module type are shown in the table below. (Refer to the Table 1)

■Process Data Mapping
R8 performs mapping of process data according to Modular Device Profile (MDP) of EtherCAT. The configuration of periodi-
cally transferred process data is created by using RxPDO and TxPDO.
R8 uses object dictionary 0x6000 to 0x61F0, 0x2000 and 0x2001 as input area, 0x7000 to 0x71F0 as output area. The items
in object in the address starting with 0x6000, 0x2000 and 0x7000 are referred in turn by RxPDO and TxPDO by using index
and sub-index. Output data is stored in RxPDO (0x1600 to 0x161F and 0x1701), input data is stored in TxPDO (0x1A00 to
0x1A1F, 0x1AFF and 0x1B01). One PDO encapsulates several data to store in one packet.
RxPDO and TxPDO are registered in 0x1C12 (output data) and 0x1C13 (input data) of PDO assign list. The list defines the
order of the cyclic transfer of each PDO data.
MDP model is shown in the figure below. (Refer to the Figure 1)

■EtherCAT State
EtherCAT defines four states of slave: INIT, PREOP, SAFEOP, and OP.
TxPDO (input process data) can operate only in the SAFEOP or OP state, and RxPDO (output process data) can operate only
in the OP state.
There are 4 types of I/O cards connected; they are analog input, analog output, discrete input, and discrete output. For input
card, the RUN LED turns on only in the SAFEOP or OP, for output card, RUN LED turns on only in the OP state OP.

OBJECT DICTIONARY
■Input Area objects (0x6000 to 0x61F0)
In the object 0x6000 to 0x61F0, input data of I/O module is stored. For one input module, one object exists. Index of the object
is fixed by module number (0 to 31 = I/O card address).
Index = 0x6000 + (module number) × 0x0010
The configuration of the object is fixed by data type per one point of input point. (Refer to the Table 1 and 2)
■Output Area objects (0x7000 to 0x71F0)
In the object 0x7000 to 0x71F0, output data of I/O module is stored. For one output module, one object exists. Index of the
object is fixed by module number (0 to 31 = I/O card address).
Index = 0x7000 + (module number) × 0x0010
The configuration of the object is fixed by data type per one point of output point. (Refer to the Table 2 and 3)

■Manufacturer Specic objects (0x2000, 0x2001)
Status data of I/O module is stored in the object 0x2000 and 0x2001. This object is created regardless of configuration of I/O
modules.
Input abnormal data of module 0 to 31 (I/O card address 0 to 31) is stored in 0x2000 as 2 bits. When corresponding module is
analog input module and first point or second point input is out of -5 to +105% range or burnout state, bit [second point: first
point] of corresponding input is set to 1. When corresponding module is other than analog input module, [0 : 0] is set.
Status data of module 0 to 31 is stored in 0x2001 as 32 bits. LSB corresponds module 0, MSB corresponds module 31. A bit
for normally existing module is set to 1, a bit for not existing module or module having hardware error (including communica-
tion error) set to 0. (Refer to the Table 4)

■PDO Mapping objects (0x1600 to 0x1701, 0x1A00 to 0x1B01)
• Object 0x1600 to 0x161F, 0x1A00 to 0x1A1F
RxPDO (from 0x1600) is used for the output module, and TxPDO (from 0x1A00) is used for the input module.
Object index of RxPDO is allocated number of output module according to MDP specification.
Index = 0x1600 + (module number of output module)
Object index of TxPDO is allocated number of input module according to MDP specification.
Index = 0x1A00 + (module number of input module)
In the data of RxPDO and TxPDO, index, sub-index, and the number of bit of each object which is referred to, are stored.
For data of the input module, each object with the address starting with 0x6000 is referred to.
For data of the output module, each object with the address starting with 0x7000 is referred to.

• Object 0x1701, 0x1B01
0x1701 of RxPDO and 0x1B01 of TxPDO are used to add empty bit in the end of periodically updated process data. Because
some discrete module has 1 bit, 3 bits or 4 bits data on the other hand analog modules have 16 bit data, bit length is fixed at
the time PDO is configured so that the end of consecutively configured process data terminate just on the border of 16 bits.

■PDO Assign objects (0x1C12, 0x1C13)
Allocation list for PDO is created in 0x1C12 and 0x1C13. The entire list for RxPDO is stored in 0x1C12, the entire list for
TxPDO is stored in 0x1C13. The index stored in 0x1C12 and 0x1C13 is placed in order that is transferred by PDO.
• PDO group
In R8, PDO group defined by Modular Device Profile (MDP) is sorted by I/O module type. The sorting is defined by object
0x9000.
•PDO group 0: PDO for R8 status
•PDO group 1: PDO for analog input module and analog output module
•PDO group 2: PDO for discrete input module and discrete output module
• Allocation of PDO list
The order in the list for RxPDO and TxPDO is as follows.
Group 0 => Group 1 => Group 2 => empty bit PDO
The order in the same group is in ascending order of object index (I/O card address).

DIAGNOSTIC
■Internal Bus Error Detection (at power on)
When the power of the unit turns on, if an I/O card has a fault with the internal bus or the card address is duplicated with
another card, the R8-NECT1 detects the fault and ERR LED blinks. In such a case, check if the address is duplicated at first.
(A 4-point analog I/O card uses 2 successive card addresses. Be careful with duplication of the address.)
When the unit detects an internal bus error, the state transition from INIT to PREOP cannot be done despite state machine
from the master.
■Internal Bus Error Detection (at operation)
If an I/O card has a fault with the internal bus during normal operation, the R8-NECT1 detects the fault and set the error
code in AL Status Code, and ERR LED blinks. If the EtherCAT state is OP, the state transits to SAFEOP.
When the internal bus error is recovered, the ERR LED turns off and error code is reset. However, the state remains at
SAFEOP. To transit to OP state, send command from the master.
■Card Address Conrmation
Set SW1-8 on and turn on the power, then the R8-NECT1 starts in Card Address Confirmation mode.
The RUN LED of I/O card flashes from address 0. When the card uses 2 addresses, the LED flashes twice.
Repeating the flashing from address 0 to the last address. (In operation mode, non-continuous address does not affect the
operation. However, in this mode, the unit ignores the addresses following the unused one.)
The time of flashing is On for 400 msec., and Off for 100 msec.
In order to change the mode to operation, turn SW1-8 off and turns the power on again.
■AL Status Code
If State machine cannot be accepted, or a slave makes a fault during communication, the salve sets error code in register
0x0134: 0x0135 (AL Status Code) of ESC.
The error codes of R8 series are shown below. (Refer to the Table 21.)

■SDO Abort Code
If a slave cannot accept during SDO access to object dictionary by the master, the slave sends the error code (SDO Abort Code)
and denies access.

■RUN LED of I/O Card
Each I/O card connected to the R8-NECT1 has a RUN LED.
The RUN LED turns on when the card communicates with the master and the system bus runs correctly.
If the card is input card (analog input or discrete input), when state of the R8-NECT1 is OPERATIONAL or SAFE-OPERA-
TIONAL, it turns on. If the card is output card (analog output or discrete output), when state is OPERATIONAL, it turns on.
PDO communications of I/O cards are available only when RUN LED turns on.
