CHAPTER 5: ETHERCAT DATA STRUCTURE
5.1 Programming / Monitoring Values Translation
EtherCAT communication interface preserves power supply resolution and accuracy, according to
specifications.
Programming / Monitoring values are represented in a form of 16 bits unsigned integer value. Rated Voltage,
Current and Power (nominal values) are represented as 53620 in a decimal base or 0xD174 in a hexadecimal
base.
For example, 10 Volts, 500 Amperes, 5000 Watts power supply programming and monitoring values are
represented as follows: 10 Volts = 53620, 2 volts = 10724 = 0x29E4
500 Amperes = 53620, 400 Amperes = 42896 = 0xA790
5000 Watts = 53620, 2500 Watts = 26810 = 0x68BA
600 Volts, 2.8 Amperes, 1680 Watts power supply programming and monitoring values are represented as
follows: 600 Volts = 53620, 100 Volts = 8937 = 0x22E9
2.8 Amperes = 53620, 2 Amperes = 38300 = 0x959C
1680 Watts = 53620, 680 Watts = 21703 = 0x54C7
Voltage, Current and Power values are limited to 105% (0xDBED) programming range. Protection functions
such as OVP are model dependent, ranging from 110% (0xE666) up to 120% (0xFB58) according to model
specifications (refer to power supply Instruction Manual).
NOTE
Values translation from real number (voltage, current, power, etc…) into unsigned 16 bits integer
(hexadecimal) representation may require rounding. Round naturally to the nearest unsigned 16 bits
representation.
Translation formula from actual value to programming / monitoring hexadecimal value is as follows:
ℎ  =     
 ()  ∗53620
Translation formula from programming / monitoring hexadecimal value to actual value is as follows:
     = ℎ 
53620 ∗()
NOTE
Decimal 53620 value is represented as 0xD174 hexadecimal value. Formulas above are shown in Decimal
base. Power supply operates with hexadecimal values.

13
5.2 Data Type
EtherCAT communication interface utilizes four data types: char, uint16, uint32 and float. Each SDO/PDO
holds 16 bits of data.
Char data type is used for strings represented as ASCII characters. Size of char is 1 byte.
Char data type example - *IDN? query (address 8196, 100 bytes, 50 SDOs) for 100 Volts, 50 Amperes power
supply: TDK-LAMBDA,G100-50-ETHERCAT,12345-123456,G:02.105.

NOTES
1. * Last 0 is added as the initial register value is 0, this value is not part of the *IDN? string.
2. Always start SDO access from the first SDO address according to commands mapping table (refer to
Section 5.8) for each command / query. Access to any other SDO won’t represent the actual data. For
example for *IDN? query, always read from address 8196.
3. SDOs 8221 ~ 8245 contain 0.
Uint16 data type is the most common type used for most of the functions. Size of uint16 is 2 bytes.
Uint16 data type example – MEASure:VOLTage[:DC]? query (address 8271, 2 bytes, 1 SDO) for 100 Volts
actual output value in a 100 Volts (nominal) power supply: 53620 = 0xD174
SDO Address Decimal value Hexadecimal Data
8271 53620 D174
Uint32 data type is used to query power supply operation time. Size of uint32 is 4 bytes.
Uint32 data type example – SYSTem:PON:TIME? query (address 9190, 4 bytes, 2 SDOs). 100 hours
operation time is represented as:
SDO Address Decimal value Hexadecimal Data
9190 100 0064
9191 0 0000
Float data type is used for sequencer time / dwell programming and voltage / current slew rate control. Size of
float is 4 bytes, represented according to IEEE 754 standard.
Float data type example – [PROGram]:LIST:DWELl? query (address 8388, 400 bytes, 200 SDOs). One
second dwell for a single sequence point is represented as: 0x3F800000. Rest of the cells contain 0 if not
used.
SDO Address Decimal value Hexadecimal Data
8388 0 0000
8389 16256 3F80
NOTES
1. Always start register access from the first register address according to commands mapping table (refer
to Section 5.8) for each command / query. Access to any other SDO won’t represent the actual data. For
example for [PROGram]:LIST:DWELl? query, always read from address 8388.
2. First sequencer point always starts at the first register address.

15
5.3 Data Access
EtherCAT supports two types of data access operations: Read or Write. Query commands (SDOs) have Read
access only.
NOTES
1. SDOs which don’t have Read access return 0.
2. Write of an out of range value results in an error. It is recommended to read SDO 9128 (SYSTem:ERRor?
query) to verify no errors.
5.4 Data Length (Number of SDOs/PDOs)
Each SDO length is 2 bytes. Read/Write of multiple SDOs results in Read/Write of a set of bytes multiplied by
two. For example, *IDN? query start from SDO address 8196, its length is 50 SDOs, 100 bytes. To read
multiple SDOs, read one SDO after another (one by one). Always start read process from the first SDO
corresponding to a command.
NOTE
Always start SDO access from the first SDO address according to commands mapping table (refer to Section
5.8) for each command / query. Access to any other SDO won’t represent the actual data.
5.5 Parameters Range
Each command (SDO/PDO) has a specified data range. It is mandatory to preserve data range to avoid data
overrun. For example, voltage setting range is 0 up to 105% of rated (nominal) value, translated to 0x0000 up
to 0xDBED. An out of range parameter generates an error, which can be read by SDO 9128
(SYSTem:ERRor? query).
Some other SDOs (commands) such as SDO 8194 (*ESE command), are limited to a specific range, 0 up to
255. A value out of the specified range might result in an unexpected setting value.
NOTE
It is recommended to follow parameters range specification to avoid an unexpected behavior of a power
supply.
5.6 Read / Write SDOs / PDOs
EtherCAT supports two types of Read / Write operations. Read single SDO / PDO or Write single
SDO / PDO. Each operation is defined per command (per SDO / PDO or SDOs / PDOs range).

16
5.7 PDOs Mapping
EtherCAT PDOs are mapped according to the table below. Refer to USER MANUAL (IA761-04-
02_) for information regarding commands functionality.

NOTES
1. Size of each PDO: 2 bytes.
2. An out of range parameter might result in an unpredicted behavior of the power supply.
3. Reading PDOs which have no Read access return 0.
4. PDOs which accept parameters in the range of 0,1 accept 0 as logical 0, while any number above 0
accepted as logical 1 (acts as Boolean parameter).
5. Loading a value above uint16 (above 65535) loads only 16 LSB of the value.
