Add an expansion module to a controller project

Expansion I/O modules extend the capabilities of
Micro850
 L50E and
Micro870
 L70E controllers by optimizing the flexibility of the I/O count and type.
For
Micro850
 L50E controllers:
  • Add no more than four expansion modules.
  • To avoid program compiling problems, limit the total number of digital inputs and outputs to:
    • 192 or less for
      Micro850
       L50E controllers with 48 digital I/O points.
    • 132 or less for other
      Micro850
       L50E controllers.
For
Micro870
 L70E controllers:
  • Add no more than eight expansion modules and no more than one power supply expansion module.
  • To avoid program compiling problems, limit the total number of digital inputs and outputs to 304 or less.
