AB's PLC is currently mainly divided into 5 categories:
1. The low end is MicroLogix1500, and the programming software is RS Logix500. The latest version is V6.0.
2. The mid-range minicomputer is SLC500, and the programming software is RS Logix500. The latest version is V6.0.
Can support a variety of networks, up to 4096 points of I/O.
3. The mid-range new noble is CompactLogix, and the programming software is RS Logix5000. The latest version is currently V13.0.
4. The high-end mainstream model is ControlLogix5000, and the programming software is RS Logix5000. The latest version is currently V13.0. The maximum support for 128K points of I/O. The function is very powerful, even Siemens S7-400H can not be compared.
5. The high-end old model is PLC-5, and the programming software is RS Logix5. The latest version is V5.5. The PLC-5 has basically ceased production and is currently only available as a spare part. Its status will be completely replaced by ControlLogix5000, and the supply of spare parts will be stopped around 2008.
This is AB's communication software. It is mainly used to connect the communication between group software and PLC.
It unifies various network interfaces of PLC into OPC interface at the software level.
In fact, it is a no-compromise OPC Server. No matter how the computer and PLC are connected, after using RSLinx software, it becomes a unified OPC format to communicate with the upper-level software.
