Quasi input/output interfaces are typically used to sense signals generated by sensors. These interfaces can be used to measure flow, temperature, and pressure, and to control voltage or current output devices. Typical ranges for these interfaces are – 10 to+10V, 0 to+11V, 4 to 20mA, or 10 to 50mA. Some manufacturers have designed special analog interfaces on PLCs to receive low-level signals, such as RTDs, thermocouples, and so on. Generally speaking, this type of interface module can be used to receive different types of thermocouple or RTD mixed signals on the same module.
When selecting a PLC, users may face some special types of I/O constraints that cannot be implemented using standard I/O (such as positioning, fast input, frequency, etc.). At this point, the user should consider whether the supply and marketing manufacturer provides modules that can help minimize control effects. Some special interface modules themselves can process a portion of field data, freeing the CPU from the heavy task of processing. At the beginning of the “14th Five Year Plan” in 2021, the implementation of China’s digital transformation has entered a critical “inflection point” stage. At the same time, under the requirements of the “3060 carbon target”, the transformation and upgrading of Chinese manufacturing enterprises is imminent. However, when it comes to specific applications, the digital integration of IT and OT is still a “mountain” in the face of manufacturing enterprise transformation, and it is difficult to fully exert the value of data.
PLC is developed from the principle of relay control, which stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations; Digital input and output operations are used to control various types of machinery or production processes. The control program compiled by the user expresses the technological requirements of the production process and is stored in the user program memory of the PLC in advance. During operation, execute the stored program item by item to complete the operations required by the process flow.
