摘要:
In a method for parameterizing a process automation field device which is connected to a control unit via a bus system, parameter values are packaged into messages of the cyclic services and are transmitted to the relevant field device whose parameter values are intended to be changed. Acyclic services are not required for the change of parameter values but rather the field device is informed of the address of the parameter value (slot / index) within the function block (AO block and DO block) in a message.

Techniques for network based triggering in an instrument system that enable instruments to effectively signal events without hardwired trigger lines. An instrument system 100 according to the present teachings includes a first instrument and a second instrument coupled to a local area network. The first instrument is capable of performing an action in response to an event that is signaled by the second instrument. The second instrument signals the event to the first instrument by transferring a trigger message 60 via the local area network.
摘要:
The disclosed embodiments may relate to vehicle (10) having a control system (12) located within the vehicle (10). The control system (12) may include a processor (26) and a wake-up circuit (46) coupled to the processor (26). The processor (26) may utilize a program (34) during a standby mode of operation. The program (34) is configured to provide a voltage to the wake-up circuit (46) for a first time period (T1) once an interrupt is received by the processor (26). Then, the program (34) may monitor the wake-up circuit (46) for a second time period (T2). If a response of the wake-up circuit (46) exceeds at least one of a plurality of predetermined limits, then the program (34) may recalibrate the wake-up circuit (46).
