Embodiment 1

[0060] The following introduces Embodiment 1 of a remote switching method of an IO module channel provided by the present application, see figure 2 , embodiment one includes:

[0061] S201. Generate a corresponding device description file according to the user's configuration operation on the operation interface, the device description file includes parameter data used to describe the working state of the channel, and also includes the length of the interaction data used to describe the channel and the field device and configuration data of type;

[0062] S202. Send the device description file to a software-configurable IO module, so that the IO module switches the channel state between itself and the field device to a target channel type according to the device description file.

[0063] In the field of industrial control, the IO module is generally described through a device description file, which tells the user how to interact with the field device in a machine-readable ...

Embodiment 2

[0071] Specifically, the second embodiment describes in detail the process of switching the channel type of the IO module. see Figure 5 , embodiment two specifically includes:

[0072] S501. Generate a corresponding device description file according to the pre-generated device description file template and the user's configuration operation on the optional items in the device description file template on the operation interface;

[0073] Specifically, this embodiment organizes the data that does not change with the channel type and the data that cannot be configured by itself into a device description file template in advance, and provides users with options in the device description template, so that the user can perform configuration operations and improve configuration efficiency.

[0074] S502. Send the device description file to a software-configurable IO module through the photoelectric transceiver module;

[0075] S503. The IO module respectively switches the channel...

Abstract

The present application discloses a remote switching method, device, equipment and distributed control system for IO module channels. The parameter data of the working state of the channel, including the configuration data used to describe the length and type of the interactive data between the channel and the field device; send the device description file to the software-configurable IO module, so that the IO module can be configured according to the device description file Switch the channel state between itself and the field device to the target channel type. It can be seen that this solution allows users to switch the type of IO module hardware channels on the field side through remote configuration operations. It does not require users to go to the field side to replace IO modules, saving labor costs and time costs, and improving channel switching efficiency.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a method, device, equipment and distributed control system for remote switching of IO module channels. Background technique [0002] With the development of economy and technology, the scale of the factory is getting bigger and bigger, the equipment is more and more, and the devices and components are more and more scattered. In a large chemical plant, due to the dispersion of devices and the existence of dangerous gases, the difficulty of plant design is greatly increased, and the design cycle of the plant is lengthened. Moreover, after the design is completed, due to the increase in the number of equipment and the dispersion of devices, on the one hand, construction is difficult and the construction period becomes longer; At the same time, it also brings indirect problems such as cable repair and maintenance difficulties in the later stage of operation, and po...
