PLC如何编程，实现使用HMI和MCP面板切换MCS / WCS？


处理程序如下：

U E 5.4            // WCS-MCS changeover button on the machine control panel
FP M 18.0          // Free bit memory
= M 18.1           // Free bit memory
UN M 18.1
UN DB19.DBX 20.7   // Changeover via an SK on HMI 1 PLC cycle
SPB abc
UN DB19.DBX0.7     // Changeover, MCS/WCS
= DB19.DBX0.7
abc: U DB19.DBX0.7
= A 3.5            // MCS/WCS-LED on the machine control panel
