Programmable logic controller and method of operation thereof.

摘要

A method is provided for configuring a smart module (75A) which is coupled to a programmable logic controller (15). The controller (15) includes an initial configuration file which specifies an initial configuration for the smart module. After power up and initialization of the controller, the initial configuration file is transmitted from the controller (15) to the smart module (75A). The initial configuration file is now designated a current configuration specified by the current configuration file. Module specific information which is stored in the module is then displayed (70) to aid a user in configuring the module using a programmer 60. The user can then modify the current configuration file in response to the module specific information which was displayed. This significantly simplifies the process of configuring smart modules for the user. <IMAGE>
