Embodiment 1
[0090] Such as figure 1 As shown, a programmable dual-field bus conversion interface includes: a controller 1, and an NCUC bus communication module 2 connected to the controller 1, a Profibus-DP bus communication module 3, a serial communication module 4, and a network communication module 5 and a device selection switch module 6; the controller 1 in this embodiment is a STM32F103RET6 microcontroller 1.
[0091] The controller 1 includes a first communication control module for controlling the two-way communication between the NCUC bus communication module 2 and the serial port communication module 4; a second communication control module for controlling the communication between the NCUC bus communication module 2 and the network port communication module 5 Two-way communication between; the third communication control module, used to control the two-way communication between the Profibus-DP bus communication module 3 and the serial port communication module 4; the fourth com...
Embodiment 2
[0108] This embodiment utilizes the method for performing programmable dual-field bus conversion through the interface as described in Embodiment 1:
[0109] Step S1, setting system parameters and initializing each communication module;
[0110] Step S2, the device selection switch module 6 obtains a key selection signal input by the user;
[0111] Step S3, judge whether the user selects any one of the five switches of the equipment selection switch module 6, if so, then enter step S4, if not, then return to step S2;
[0112] Step S4, judging that the switch selected by the user is the first switch Key1, the second switch Key2, the third switch Key3, the fourth switch Key4 or the fifth switch Key5;
[0113] If the first switch Key1 is selected, then start the first communication control module to control the two-way communication between the NCUC bus communication module 2 and the serial port communication module 4;
[0114] If the second switch Key2 is selected, then start ...
