Abstract

A safety function executing at a periodic interval on a pair of controllers is modified during execution by preparing a change record for the safety function in response to an edit request. A communication channel is established between a first core on each controller via a dedicated communication interface. The change record is transmitted between the first core of each controller via the communication channel. The change record is transmitted from the first core to a second core of each controller. Preparing the change record, establishing the communication channel, and transmitting the change record combined execute over multiple periodic intervals for the safety function. The change record is stored in a memory of each controller with corresponding second core for the controller. Storing the change record in the memory of both controllers occurs during a single periodic interval for the safety function.
