Problems solved by technology

Therefore, when there are many types of sensor signals transmitted, it often cannot meet the actual needs
At this time, the interface requirements can only be met by increasing the number of I / O modules. This method increases the complexity of the automation control system and the wiring redundancy, so it is not conducive to the early wiring arrangement and later maintenance; and when the type of sensor signal is large When the number of sensor signals of each type is small, the utilization rate of the I / O module will not be high in the above method as a whole, resulting in waste of I / O modules
[0004] Moreover, in the existing automatic monitoring system, since the interface type of the I / O module is single and solidified, when replacing the electrical equipment at the controlled end or the sensor on the electrical system, it is necessary to carry out overall rewiring first; if the I / O There is no corresponding interface on the module, and sometimes a new I / O module needs to be purchased
Not only increases the difficulty of sensor replacement, but also takes a long time and has low flexibility

Abstract

The invention provides a remote I / O (input / output) module of a PLC (programmable logic controller) and a configuration method thereof. The remote I / O module of the PLC controller comprises an MCU chip, an equipment end interface, a controller interface and a nonvolatile memory; the device end interface and the controller interface are respectively connected with the MCU chip through corresponding circuits, and the nonvolatile memory is also connected with the MCU chip. Therefore, the interface requirements of any type of sensors and any number of sensors can be met through a single I / O module. In the configuration method, the I / O module identifies and transmits sensor signals under different sensor combinations. The real-time configuration method is used for performing remote or local programming based on the MCU chip; therefore, the updating flexibility of the PLC control system is improved when the sensors or the configuration parameters of the sensors are changed according to the updating of the specific sensors on the configuration files and the configuration programs in the sensors.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a remote I / O module of a PLC controller and a configuration method thereof. Background technique [0002] PLC (Programmable Logic Controller, Programmable Logic Controller) is a digital electronic device with a microprocessor, which has important and extensive applications in realizing the automation control of electrical equipment and electrical systems. [0003] Existing industrial automation control systems generally include electrical equipment or electrical systems as the controlled end, PLC controllers as the control end, and I / O modules that establish connections between the two. However, in the existing I / O modules, the types of interfaces used to transmit the signals of the sensors at the device end are fixed, that is, there are only fixed numbers and fixed types of interfaces. Therefore, when there are many types of sensor signals to be transmitted, it of...
