  1. Micrologix 1000 DDE Demo

    This is a demo of a simple temperature sensing demo that utilizes a Micrologix 1000 PLC and an Analog Devices Inc. AD590 temperature transducer. This demo should help with the understanding of analog inputs on the Micrologix PLC.

  2. Dialing a Cell Phone with a Micrologix 1500 using a Modem Attached

    This wasn’t a normal “job” per say but more like helping our machinist staff from babysitting the Japax Wire EDM machine. For those of you that don’t know a wire EDM can take a long time to make cuts in a part sometimes. There was a part that we made t

  3. TRUNCATE IEEE754 FLOAT

    Sometimes is necessary to truncate (remove the fraction) or round a floating point number that is outside the range of -32678 to +32767 - making it impossible to use a MOV to an integer to make the conversion.
    This is a program I worte that shows how to perform a truncation directly on the floating point number by copyng the 32 bit pattern of the float and then determining which bits of the mantissa to keep and clearing all the rest. It includes three subroutines two of which show two different methods of truncating the float and a third which rounds the float to the nearest whole float.
    An understanding of the IEEE-754 float format is helpful in understanding how this program works but its not necessary to use it.
