ABSTRACT:
A controller for a line regulation device such as a voltage regulator is provided with an interface to a removable memory module. The memory module is preferably of the memory card type which can be carried by a field engineer in a clothing pocket. When the memory card is inserted into an externally accessible slot in the controller, its presence is signaled to the controllers microprocessor. In response, the microprocessor reads user selected control parameters which are entered via the controller's front panel. Depending on the control parameters, the microprocessor updates the programming code in its internal memory, executes the code stored in the memory card while it is present but does not update its internal memory, or dumps selected status information to the memory card so that it can be analyzed at a different location.
