140ACI03000 SCHNEIDER
Schneider Electric 140ACI03000 is part of the Modicon Quantum PAC series, with many outstanding features. Kunteng provides a truly collision free hot spare. Quantum processors can be programmed using Unity Pro software, and can also support traditional 984 ladder logic programs in the LL984 Unity Pro editor by simply importing legacy applications. The Kunteng platform also supports concepts ™ Application software and ProWORX ™ 32 Application software. The onboard memory of Unity Quantum can exceed 3 MB, and the PCMCIA card can have more than 7 MB of extended memory for data and application storage. It can also provide more than 8 MB of data storage alone. Kunteng PLC also provides certified secure PAC versions that can be used in applications up to SIL3. This includes standard and hot standby functionality as well as redundant I/O.
Working data is some data that is frequently changed and accessed during PLC operation. Stored in RAM to accommodate random access requirements. In the working data memory of the PLC, there is a storage area for storing logic devices such as input/output relays, auxiliary relays, timers, counters, etc. The status of these devices is determined by the initial settings and operation of the user program. As required, some data is maintained in its current state using a backup battery during a power failure. The storage area where data can be stored during a power failure is called the retention data area.
Since the system program and working data are not directly related to the user, the form and capacity of memory listed in the PLC product sample or user manual refer to the user program memory. When the user memory capacity provided by PLCs is insufficient, many PLCs also provide memory expansion functions.
Input/output units, also known as I/O units or I/O modules, are connecting components between PLC and industrial production sites. PLC can detect various data of the controlled object through the input interface, and use these data as the basis for PLC to control the controlled object; At the same time, PLC sends the processing results to the controlled object through the output interface to achieve control purposes.
