在线编程可以减少现场访问和人工操作，从而减少SCADA系统的建设和运行。控制系统集成商利用现成、廉价和经验证的技术以及在线编程，只需给系统打电话，而不是访问系统现场，就可以对大多数监控系统编程进行修改。供水系统运营商可以利用在线编程来监控美国大陆任何地方的供水系统、抽水站和水处理厂。该系统的许多优点之一是纠正问题的速度。由于行程时间和日程安排的原因，可能需要几天才能纠正的编程问题可以在不到一个小时内纠正。 因此，停止服务的时间和服务呼叫的成本一起减少。

On-line programming can reduce SCADA system construction and operation by reducing on-site visits and manned operation. Utilizing readily available, inexpensive and proven technology together with on-line programming, Control System Integrators can make most supervisory control system programming modifications by simply placing a telephone call to the system rather than visiting the site of the system. Water system operators can utilize on-line programming to monitor and control water systems, water pumping stations, and water treatment plants from anywhere in the continental United States. One of the many advantages of this system is the speed with which problems can be corrected. Programming problems which may have required several days to correct because of travel time and scheduling, can be corrected in less than an hour. As a result, out of service time is reduced along with the cost of the service call.
