When you need to use DeviceNet Config software to read the parameters in the custom
equipment, you have to first make sure that the equipment supports the Modbus function
code, 0x03 (read), 0x06 (write) and so on.
You have to acquire the Modbus address of the parameter before reading the parameter.
How to read: Plus 0x0001 in Modbus address as Instance value and 0x0001 as Attribute
value.
Assume you read the Modbus address of the custom equipment as 0x011E, use DeviceNet
Config software and read Instance = 0x011E + 0x0001 and Attribute = 0x01.
