4.6.7 Modbus Input Setup Registers

Configuration of the IO-FEP2 inputs starts at register 01001. The setup data for each input covers 20 registers, meaning that the setup configuration for input 2 starts at 01021, for input 3 at 01041 and so on. Setup of input 48 starts at address 01941 and ends with and including 01958.

Inputs which are not licensed are forced to "not used" by the. IO-FEP2 Configuring them to an active state has no effect.

The register definitions for input 1 are:

  Register    Purpose               Remarks
  
  01001       input 1 type          0 = not used
              definition            1 = normal input
                                    2 = alarm input
  01002       input 1 name          up to 29 characters + 
                                    0-termination in 15
                                    registers
  01017       input 1 invert        0 = not inverting, current flow
                                        causes a '1' bit.
                                    1 = inverting, missing current
                                        causes a '1' bit
  01018       input 1 delay         msecs
