Software PLC is a software technology designed to turn an embedded computer into a fully functional and programmable logic controller, also known as a PLC. It combines PLCs’ discrete, PID and analog I/O control with high performing computer networking, data handling, and computational capabilities.
PLC complete solutions from SUNCARRY have everything that solar system needs. PLC, Touch Panel/HDMI and Software for Windows NT/2000/XP/Vista. The software is programmed in visual studio.NET and using Modbus protocol. Online connections with PLC run-time systems around the world can be implemented with TCP/IP. Changes to programs or data are supported, which can also operate over a network.
Application programming
Software PLCs support loadable functions developed by users and developers in Java, C, or C++ languages. They also support online run mode program alterations, different program documentation modes, and I/O forcing. Software PLCs are programmed with at least 6 different types of coding languages to ensure that they provide a wide range of online troubleshooting, development and documentation features as well as run converted or imported programs.
Capacity
Software PLC systems have the capacity to regulate over 16K I/O which includes analog, digital and specialty I/O. You can mix up to 16 different I/O systems on a single software PLC regulator; it can hold up to 36 COM ports affiliated to serial devices for ASCII communications and 32 user-configurable data paths and networks as main communication channels that allow data access from different computer PLCs or applications. Additionally, software PLCs can hold huge application programs and 100 million data table elements.
Hardware and operations
A software PLC operates as an embedded 32-bit multi-tasking kernel that performs its duties in real-time on different CPUs, including the x86 compatible CPU platforms. It is independent of hardware busses like ISA, VME, PC/104, and PCI. It operates under minimal hardware requirements, which ensures high reliability at low costs.
Communication
Software PLCs feature built-in communication ports that include different protocols. However, most of the included protocols are vendor-specific while the PLCs have the capacity to communicate over a reliable network to other systems, like computers operating under SCADA system or regular web browsers. On the other hand, PLCs used in large I/O systems operate under peer-to-peer (P2P) communication over different data processors. P2P communication allows different segments of an otherwise complex process to run individually while still allowing their sub-systems to coordinate over a single communication link.
