【Reading guide】Mainstream PLC brand introduction series of Rockwell。 Do you know what the first PLC in Rockwell looked like?
ControlLogix系列
ControlLogix is a high-end PLC for large-scale and complex control systems, high-end mainstream models, with high performance, large capacity, high reliability, modular design, powerful communication functions, rich programming tools, good real-time, high security, easy configuration and programming, such as ControlLogix 5580, ControlLogix 5570, etc., equivalent to Siemens S7-400 and 1500, the early use of RSLogix The latest version of the 5000 (equivalent to Siemens' SIMATIC-STEP7) programming software is RSLogix 5000 V21, and is now also available for Studio5000 (equivalent to Siemens' TIA Portal), and the latest version is Studio5000 V36.
CompactLogix系列
CompactLogix is a mid-range model with high performance, modular design, high reliability, rich communication interfaces, miniaturization, rapid deployment, powerful diagnostic functions, high cost-effectiveness, and scalability, such as CompactLogix 5480, CompactLogix 5380, etc., in order to replace the SLC500 series, which is equivalent to Siemens S7-300 and 1200, RSLogix was used in the early days The latest version of the 5000 (equivalent to Siemens' SIMATIC-STEP7) programming software is RSLogix 5000 V21, and is now also available for Studio5000 (equivalent to Siemens' TIA Portal), and the latest version is Studio5000 V36.
SLC500 series
SLC500 is a mid-range model, with high stability, rich functions, simple programming, hardware can adapt to harsh environments, rich instructions, good compatibility, strong communication capabilities, equivalent to Siemens S7-300, using RSLogix 500 (equivalent to Siemens SIMATIC-STEP7) programming software, the latest version is RSLogix 500 V16.
MicroLogix series
MicroLogix is a compact PLC suitable for small applications, low-end model, with small size, low cost, simple use, rich functions, high reliability, scalability, rich communication interfaces, and friendly programming software, suitable for small equipment, simple process control occasions, such as MicroLogix 1400, equivalent to Siemens S7-200. The latest version of RSLogix 500 (equivalent to Siemens' SIMATIC-STEP7) is currently RSLogix 500 V16.
PLC-5 series
PLC-5 is a classic PLC series, high-end old models, still used in some old systems, stable performance, powerful internal functions, rich resources, firm structure, easy replacement of modules and terminal terminals, strong shock resistance, corrosion resistance, allowed to work at a higher working ambient temperature, equivalent to Siemens S5 series, using RSLogix 5 (equivalent to Siemens STEP 5) programming software, the highest version V5.5. This series has basically been discontinued, and only spare parts are currently supplied.
Rockwell's first PLC
The 1774PLC (known as PLC-1) was the first programmable controller introduced by Allen-Bradley in 1970 and coined the term PLC (Programmable Logic Controller). PLC-1 was followed by PLC-2 and PLC-3, and then PLC-5 series products; the SLC500 series, released in 1990; In the years that followed, the CompactLogix series and the MicroLogix series were introduced, which have been developed to this day.
