3HAB2211-1 Triple modular redundancy main processor module
ABB 3HAB2211-1 is a triple modular redundancy (TMR) main processor module. The main function of this module is to improve the reliability and availability of the system through redundant design.
Specifically, the TMR technique works by introducing three identical modules working in parallel into the system and comparing their outputs to detect and correct any possible errors. If one module fails, the other two modules can continue to work, thus ensuring the normal operation of the system.
In ABB’s automation systems, TMR main processor modules such as 3HAB2211-1 have the following functions:
High-speed, robot motion control: ABB’s TrueMove and QuickMove motion control systems may be used to improve the accuracy and speed control of robots in high-speed motion.
TCP calibration: Using ABB’s bull’s eye technology, it can be applied not only in the field of arc welding torch TCP calibration, but also in various tools such as laser cutting and welding.
Highly environmental simulation: ABB’s self-developed Robot Studio software may be dedicated to the simulation of robot work scenarios, including I/O simulation, collision avoidance monitoring, path generation, program generation and other functions.
Redundancy functions: With specific redundancy modules, such as the 1757-SRM, redundancy functions can be implemented without any programming and can easily align programs within the master and slave processors. When the main processor fails, the slave processor can take over the control system to ensure the continuous operation of the system.
