A3120022-000 CSI3120 Control Board

The A3120022-000 CSI3120 enables multi-loop digital control with just one microprocessor, thanks to its ability to run electronic control algorithms at variable speeds using “time-sharing” computing power. Furthermore, the microprocessor’s innate aptitude for data archiving, transmission, and networking makes it an appealing option. A lone computer can manage 530 controls on numerous loops and provide accessibility of loop control data between loops (for arcades, ratios, forward, and other control strategies) on a network for hassle-free access by operators and technicians. This direct digital control (DDC) has been effectively utilised in resolving building automation issues where temperature and humidity regulation of vast structures is attained through large-scale data integration.

The data development centre employs a centralised, network-focused methodology. The A3120022-000 CSI3120 is gathered through multiple analogue and digital converters, which transmit signals via the network to a central controller. The central computer adheres to production rules, potentially incorporating sensory points throughout the structure, and transmits instructions through the same network to valves, actuators, and other adaptable components of the high-pressure air conditioner. This process involves rapid, continuous evaluation of each of the 530 equations.

There are no evident light-emitting diodes to indicate the system status on this panel. Hence, software operating on networked PCs is a must for operators, engineers, and technicians to access the data of this control system. The A3120022-000 CSI3120 uses LOOKIN as its communication protocol, not Basnet. Akin to Baknet, Ronk is another upper layer protocol transmitted over Ethernet and simpler serial communication formats. The ECP-410DDC model controller has a two-wire connection for its remote network. The programming of the DDC controller ranges from a text-based language (similar to Basic language) to function block programming. A3120022-000 CSI3120 serves as an example of a controller programmed in text, while the Distech EC-410 supports function blocks as well as text-based programming.
