IC690RFH008 PLC basic technology progress, mainly focused on two basic aspects: the implementation of multi-task and program interchange.

IC690RFH008 The so-called execution of multi-task, is in a PLC system can be installed at the same time several CPU modules, each CPU module to execute a certain task, control the task related to the I/O module access. In fact, according to IEC 61131-3, we should more accurately call it multitasking through multiple configurations. Mitsubishi Electric’s Small Q series, for example, can fit up to four CPU modules into a rack; Fujifilm Electric’s MICREX-SX series can fit up to six CPU modules in one rack.

IC690RFH008 These CPU modules can be dedicated to logic control, sequence control, motion control, or process control. The above modules that perform PC tasks in the Windows operating system are also an option for users to choose. In a sense, this is also a hybrid control system
