EtherNet/IP for variable frequency drive DE1/DC1
EATON
www.eaton.com
Actual speed
The DE1/DC1 variable speed starter’s actual speed will fall within a range of P-02 (min. frequency)
to P-01 (max. frequency). In the application, the value will be scaled by a factor of 0.1.

Process data out 3 (PDO3) – motor current
The permissible value is to provide the motor current. The current is
specified with one decimal place.
Example: 34 = 3.4 A.
Process data out 4 (PDO4) – not used
The value is not used.
Acyclic data
Drive Parameters, Control and Status Registers can be Read by:
•
individually using Parameter or Modbus Object
•
in a block of 1-123 using the Modbus Object
•
in a block of 123 using Assembly Object
Drive Parameters, Control and Status Registers can be Written by:
•
individually using Parameter or Modbus Object
The DC1 and DE1 Drives do not support Modbus multiple register
writing and therefore, although supported by the EIP module, the
following cannot be used for writing:
•
Modbus Object (in a block of 1-123)
•
Assembly Object (in a block of 123)
Mapping: Instance x = Modbus Register Holding Register x (2 Byte)
PDI/PDO:
Instance 1 = Modbus Register Holding Register 1 = PDI1 (2 Byte)
Instance 2 = Modbus Register Holding Register 2 = PDI2 (2 Byte)
Instance 3 = Modbus Register Holding Register 3 = PDI3 (2 Byte)
Instance 4 = Modbus Register Holding Register 4 = PDI4 (2 Byte)
Instance 5 = Modbus Register Holding Register 5 = PDI1 (2 Byte)
Instance 6 = Modbus Register Holding Register 6 = PDI2 (2 Byte)
Instance 7 = Modbus Register Holding Register 7 = PDI3 (2 Byte)
Instance 8 = Modbus Register Holding Register 8 = PDI4 (2 Byte)
Instance x = Modbus Register Holding Register x = (2 Byte)
PDO registers can be read:
•
individually using Parameter or Modbus Object
•
in a block of 4 using the Modbus Object (recommended)
•
in a block of 123 using Assembly or Modbus objects
PDO registers can be written:
•
individually using Parameter or Modbus Object
For example:
Class 0x0F (Parameter), Service 0x10, Instance 1, Attribute 1 with
2 Data bytes will write the PDI1 register
Class 0x0F (Parameter), Service 0x10, Instance 2, Attribute 1 with
2 Data bytes will write the PDI2 register
Etc.
Class 0x44 (Modbus), Service 0x50, Instance 1, Attribute 1, Start
Address 1 and Len 1 with 2 Data bytes will write the PDI1 register
Class 0x44 (Modbus), Service 0x50, Instance 1, Attribute 1, Start
Address 2 and Len 1 with 2 Data bytes will write the PDI2 register
Etc.
Class 0x0F (Parameter), Service 0x0E, Instance 1, Attribute 1 will
read the PDI1 register
Class 0x0F (Parameter), Service 0x0E, Instance 2, Attribute 1 will
read the PDI2 register
Etc.
Class 0x44 (Modbus), Service 0x4E, Instance 1, Attribute 1, Start
Address 5 and Len 4 will read the 4 PDO registers
