Parameter P00x overview
Each Modbus slave device needs a unique device address (ID) in the network. It can be set with P001. All other Modbus
network properties can be set with parameter P002, P003 and P006.
With parameter P005 the write access to the parameter via Modbus master is disabled (except P005 can always be
written).
P004 is not used.
