8200-1302 HMI Inverter

The 8200-1302 is very simple and convenient to use and program. It has the following features: (1) it can easily realize the data exchange with plc; (2) it can control the soft relay inside the plc by the 6 function key switches that come with itself, thus it can reduce the use of input points of plc; (3) it has two communication ports, one rs232c (used for communicating with PC) and one rs422 (used for communicating with plc), using the computer and f920got to connect with the PC, it is very easy to use and program the f920got.

The computer and f920got can not only read and upload the program to the hmi, but also can directly upload and download the program to the plc, adjust and monitor. 8200-1302 use two high-speed counters c235 and c236. c236 is used to display the current position of the feed mechanism by calculating the number of pulses for forward and backward, and then converted to display the current position of the feed mechanism; c235 is used to carry out precise positioning.

The difficulty of the program in the 8200-1302 project mainly lies in the processing of data. In the paper cutting machine in the working process in addition to manually let the feed positioning mechanism forward and backward, but also to realize the equal parts cutting function and specify the specific location of the positioning function, and hmi also instantly display the current position of the positioning mechanism. In order to simplify the calculation in the program,
