摘要： When modifications in a process control system are made, the software modifications must be made in the camera linked to the system, too. Both a programmer skilled in the process control system and a programmer skilled in camera programming are needed. This can be avoided when an adaptation program (710) is made for a smart camera (71). This program is able to transform the tasks given by the programmable logic (11) to a language understood by the camera software as well as to send the task results to the programmable logic. The command tasks are transmitted from the programmable logic to the smart camera, and correspondingly, the test results are transmitted to the programmable logic in messages of a known field bus protocol (e.g. Modbus), wherein the adaptation program acts as an interpreter between the bus protocol used and the specific camera software. In addition to the adaptation program another program is made for the programmable logic; this program may include any tasks to be given to the camera image-processing program provided that the tasks are incorporated in the adaptation program. The logic (11) program can now be modified at any time on the condition mentioned above, it can be included new tasks or the parameters of the existing tasks can be modified without any need for modifications in the camera (71) software or in the adaptation program.

摘要翻译： 当进行过程控制系统的修改时，必须在连接到系统的摄像机中进行软件修改。 需要熟练的过程控制系统的程序员和熟练的相机编程的程序员。 当为智能照相机（71）进行适配程序（710）时，可以避免这种情况。 该程序能够将可编程逻辑（11）给出的任务转换为相机软件所理解的语言，并将任务结果发送到可编程逻辑。 命令任务从可编程逻辑传输到智能相机，相应地，测试结果在已知的现场总线协议（例如Modbus）的消息中传送到可编程逻辑，其中适配程序用作总线之间的解释器 协议使用和具体的相机软件。 除了适配程序之外，另一个程序用于可编程逻辑; 该程序可以包括要提供给相机图像处理程序的任何任务，前提是任务被并入适配程序中。 现在可以在上述条件下随时修改逻辑（11）程序，它可以包括新任务，或者可以修改现有任务的参数，而无需修改相机（71）软件或在 适应计划。
