Parameter programming
This is achieved through the use of the EtherNet/IP explicit messaging service.
The following services are implemented:
Service Code
Get attribute single
0E (hex)
Set attribute single
10 (hex)
With each of these services, the following objects are available:
Parameters Class
ID
Instance
Attribute
ID
Size
Weld program
96 (hex)
1
0 to FF (hex)
128 bytes
Electrode
97 (hex)
1
0 to 7
128 bytes
Calibration
98 (hex)
1
0 to 7
128 bytes
Configuration 99
(hex) 1
0
128
bytes
Data should be interpreted as 16-bit words, in little-endian format (lsb sent first). The definition of
these words can be found in the Modbus section of this manual.
For example, to modify a weld parameter in program p (0 to 255):
1.
Get the weld program from the control by sending the explicit message:
Service
Class ID Instance
Attribute ID
Data
0E (hex)
96 (hex) 1
p
none
This returns the 64-word (128 bytes) program structure.
2. Modify the parameter(s) as required.
3. Send the modified program back to the control with the explicit message:
Service
Class ID
Instance
Attribute ID
Data
10 (hex)
96 (hex)
1
p
128 bytes

Interfacing with a PLC
A separate document is available which details an example on how to interface with a
PLC.
