Parameter Data Input Area Mapping - GE D485 Instruction Manual

PARAMETER DATA INPUT
AREA MAPPING
D485 MODBUS TO DEVICENET CONVERTER – USER GUIDE
The explicit data can be further assigned to different attributes of parameter data input
mapping object B0h. Define the following four attributes out of eight bytes of explicit data.
Attribute Bytes
Attribute 1 2 bytes
Attribute 2 2 bytes
Attribute 3 2 bytes
Attribute 4 2 bytes
This can be done by using I/O data input area mapping mailbox command (04h)
1. Right click on the EndInit item and insert a new mailbox.
2. Set the command code to 04 (row 3).
3. The offset and length of attribute must be provided for each of the four attributes.
Enter 16 in the Data size field - it will automatically convert and display as 0x0010.

4. The offset and data length for each attribute in bytes in given below.
Attribute Offset
1 0x0000
2 0x0002
3 0x0004
4 0x0006
5. Enter the offset and data length values from the table above, then select the File >
Apply Changes menu item to save the changes.
