Chapter 8 EXPLICIT MESSAGE
8.1 Overview
Explicit Message is a communication process that accesses DeviceNet variables at arbitrary (event-driven)
timing. Using the communications card is capable of accessing not only standard DeviceNet variables but also
all inverter's function codes. Explicit Message lacks realtime performance, but it allows many variables to be set
or referred to. It is, therefore, suited for initial setting.
Refer to the user's manual of the connected master for Explicit Message.
- Variables usable in Explicit Message are grouped using three codes--Class (major key), Instance
(medium key) and Attribute (minor key). These three codes should be used for specifying a variable.
- A group of all variables contained in Class is called "Object."
8.2 Objects to be Used in Explicit Message
This section describes objects relating to the communications card and the inverter. Other objects that are
automatically executed by the master device are excluded in this manual.
(1) Identity object (Class 01 hex.)
This object refers to the product information of the communications card. It is a group of read-only variables.
Instance Attribute Name Description Value (hex.) R/W Data size
1 01 Vender ID Manufacturer's ID code 013F (=319):
Fuji Electric Group R Word
02 Device Type Applied device profile 0002: AC drive R Word
03 Product Code ID code of the
communications card 2403 R Word
04 Revision Software version
(Major and minor versions)

05 Status Status of the communications
card Depends on DeviceNet
specifications. R Word
06 Serial Number Serial number of the product Differs with the product. R DWord
07 Product Name Model name OPC-G1-DEV R 11 bytes
(2) Motor Data object (Class 28 hex.)
This object refers to and sets up the motor rated current and voltage. When Motor 2, 3, or 4 is selected, this
object automatically switches to the one for Motor 2, 3, or 4.
For details about motor switching, refer to the FRENIC-MEGA Instruction Manual, Chapter 5, Section 5.2
"Details of Function Codes."
Instance Attribute Name Description Value (hex.) R/W Data size

connected 07: Squirrel-cage,
induction motor
R Byte
06 Rated Current Rated current in units of 0.1 A Depends on the
inverter setting. R/W Word
07 Rated Voltage Rated voltage in units of 1 V
(base voltage) Depends on the
inverter setting. R/W Word
