"Demo mode expired" even no redundancy functions are used

Extend datasheets (redundancy, connectivity redundancy)

if Discrete Bit Areas is used some holding registers are not reset to 0

TCP Server: Exception on decrementing the library parameter MAX_MODBUS_CHANNELS

Value of MAX_MODBUS_CHANNELS, is not taken into account until the user modifies another library parameter

unexpected trigger variable if channels with trigger is moved

Modbus Slave: Exception if Number of Input Bits or Coils is higher than 65528

Modbus RTU channel handling is unexpected
