Fieldbus Spark Tester Parameter Addresses
The fieldbus parameters are 2 bytes each. The LSB will be at the lower byte offset, the MSB at the higher byte offset. As
an example the setpoint is 5000 volts (1388H in hexadecimal). The setpoint is at a word address 6. When reading the
two bytes of the setpoint the LSB (value of 88H) would be received first and the MSB (value of 13H) would be received
second. Some PLCs start with addresses of 0, some start with 1. The table below assumes the addresses start with 0.
To check the addressing, read from location 103 and you should read back a value of 15000.
