Distributed digital control system including modules with multiple stored databases and selector

A control module for a distributed digital control system, comprising:

• a digital processor unit;
• memory for storing a digital control program which is executed by the processor unit for controlling the module, and a plurality of module databases corresponding to identification numbers respectively;
• and
• a selector for inputting an identification number;
• the program being configured to control the module using a database corresponding to the identification number input by the selector.

A method of incorporating a control module into a digital control system, comprising the steps of:

• (a) providing a control module which includes:
• a digital processor unit;
• memory;
• and
• a selector for inputting an identification number;
• (b) storing a plurality of module databases in said memory, the databases corresponding to identification numbers respectively;
• (c) storing a digital control program in said memory for execution by the processor unit to control the module, the program being configured to control the module using a database corresponding to an identification number input by the selector;
• (d) using the selector to input an identification number;
• and
• (e) operatively installing the module in the control system.
