【摘要】 通过采用带MODBUS通讯功能的电子显数器，与PLC进行接线和MODBUS通讯，编写PLC程序读取电子显数器当前模高地址，通过PLC和触摸屏通讯，将压力机装模高度的设定数值与当前数值进行比较，利用比较结果进行相关控制，最终实现在触摸屏中调整压力机装模高度的功能。更多还原

【Abstract】 The electronic display with MODBUS communication function has been adopted to wire the PLC and communicate with MODBUS. The PLC program has been written to read the current die height address of the electronic display, and communicate with touch screen to compare the set value of the die height of the press with current value. The comparison result has been used for relevant control, and finally the function of adjusting the die height of the press on the touch screen has been realized.更多还原
