Abstract
An enhanced programmable controller for enabling access to data using internal variable names and public variable names on a communication control interface. The enhanced programmable controller includes a data storage device for storing data required for control. A program memory stores a sequential program. A communication interface communicate with other programmable controllers. A central processing unit executes the sequential program and controls a variable name conversion unit. The variable name conversion unit converts variable names, that are actual functional names, into physical addresses when variable name access is demanded from other programmable controllers.
