7.5. 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
7.6. Interfacing with a PLC
A separate document is available which details an example on how to interface with a
PLC.
