// This file shall contain all information about device specific parameters.
/// The aim of this file is to centralize this device specific information so that new Vendors can be added easily
/// Currently supported are Wago 750-881 and B&R X20BC0087.
/// Currently supported are Wago 750-881 and B&R X20BC0087 hopefully only the vendors have to be distinguished
/// The Modbus specification leaves room for several parameters than can vary from vendor to vendor (and perhaps also from device to device). These parameters are:
/// - Start addresses for reading input bits/registers
/// - Start addresses for reading output bits/registers
/// - Start addresses for writing input bits/registers
/// - Start addresses for writing output bits/registers
/// - Maximum number of connected IO (bits and registers)
/// - Size of the receive window (how many telegrams can be processed at the same time)
/// This file is used at two position: The majority of the functions are used to analyze devices when making the config. The minority has to be called when initiating a Modbus client so it knows about the addresses and window size.
/// - Size of the receive window (how many requests can be received and buffered)
