| Popis: | Process bus, the concept of distributed I/O for protection and control, has long been promoted as more cost-effective than traditional systems. I/O devices can potentially be manufactured as part of primary equipment, effectively eliminating the need for custom copper wiring design, installation, and terminations. A large part of the business case is that the cost of the additional devices (I/O devices and communications devices) will be more than offset by time and labor savings. However, this is only the capital cost of process bus. There is also an operating and maintenance cost to consider: will the increased number of devices that make up a process bus protection and control system lead to increased costs due to device reliability. |
