Embodiment Construction

[0036] With the development of industrialization and the gradual improvement of industrial automation level, more and more attention has been paid to the application of digital output cards in programmable logic controllers (PLC). At present, the controllability and safety of the micro-control units used in some digital output cards are relatively low, and their use has limitations. In addition, the current digital output card does not have the function of recovery diagnosis, and the fault-tolerant redundancy is low. The performance of the digital output card needs to be improved.

[0037] In view of this, the invention provides a digital output card and a digital output system.

[0038] The defects in the solutions in the above prior art are all the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions to the above problems proposed by the embodiments of the present invention below , sh...

Abstract

The invention relates to a digital quantity output card and a digital quantity output system and relates to the data processing technology field. The digital quantity output card comprises a slave station controller, a microprocessor, a digital isolator, and an output channel group. The output channel group comprises a plurality of output channels. The slave station controller is used to receive adata packet sent by a main station controller, analyzes the data packet to obtain the data to be output, and send the data to be output to the microprocessor. The microprocessor carries out output distribution processing on the data to be output, obtains control signals corresponding to each output channel, controls each output channel and carries out voltage output. The digital isolator is usedto collect the output voltage of each output channel to determine whether there is an output voltage exceeding a preset range. When there is the output voltage exceeding the preset range, the digitalisolator generates fault information corresponding to the output channel outputting the output voltage, and transmits the fault information to the main station controller. Reliable fault detection canbe performed on the digital quantity output card.
