Example

Read a P parameter after previously querying the number of parameters
- Read the number of P parameters in 1st channel
 Input :: IndexGroup = 0x122301, IndexOffset = 0x02
 Output : 1
- Read the name of the P parameter by the parameter index
 Input : IndexGroup = 0x122301, IndexOffset = 0x1b , Parameter = 1
 Output : P1
- Read the value of a P parameter by its name
 Input : IndexGroup = 0x122301, IndexOffset = 0x1c , Parameter : P1
 Output : 4711
