Abstract
A programmable controller is customized for a specific application by a function card inserted into a socket of a processor module on the controller. The function card can perform one or more tasks and may be used with different types of programmable controllers. Before the card can be used by a given programmable controller an initialization procedure must be performed to determine if the processor module and the card are compatible. As part of this procedure information about the operation of the given programmable controller is sent to the card. The card also contains functional information for each of its tasks the card provides. The functional information is sent to the processor module during the initialization procedure to enable the module to utilize the card.
