Abstract

The invention provides an EtherCAT-based digital quantity output board card, which comprises: a slave station controller used for sending master station data to a microprocessor; the microprocessor used for outputting multiple paths of digital quantity output control signals according to the received data; and a signal output circuit comprising a plurality of output channels, wherein each output channel is used for outputting a digital quantity signal according to a digital quantity output control signal, each output channel comprises a D trigger and a solid-state relay, the D trigger inputs the digital quantity output control signal output by the microprocessor, the control end of the solid-state relay is connected with the output end of the D trigger, the output end of the solid-state relay outputs a digital quantity signal, and the D trigger of each output channel outputs a control signal according to the input digital quantity to control the solid-state relay connected with the D trigger, so that synchronous output of the solid-state relays of the multiple output channels is realized.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to an EtherCAT-based digital output board. Background technique [0002] EtherCAT was proposed by Beckhoff in Germany. Due to its high real-time network performance, flexible topology, and simple system configuration, it has been more and more widely used. For example, EtherCAT-based modular PLC products have been launched. As the core component of modular PLC, digital output boards are used to output digital signals and control field devices. [0003] In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: [0004] Existing digital output boards cannot achieve synchronous output when outputting multiple channels of digital signals. Contents of the invention [0005] In order to solve the above problems, the present invention provides an EtherCAT-based digital output board, whi...
