一、设计目标
用PLC构成四节传送带控制系统
二、实验内容
1．
1．
控制要求
起动后，先起动最末的皮带机，1s后再依次起动其它的皮带机；停止时，先停止最初的皮带机，1s后再依次停止其它的皮带机；当某条皮带机发生故障时，该机及前面的应立即停止，以后的每隔1s顺序停止；当某条皮带机有重物时，该皮带机前面的应立即停止，该皮带机运行1s后停止，再1s后接下去的一台停止，依此类推
2．I/O分配
输入
输出
起动按钮：
I0.0 M1：Q0.1
停止按钮：
I0.5 M2：Q0.2
负载或故障A：I0.1
M3：Q0.3
负载或故障B：I0.2
M4：Q0.4
负载或故障C：I0.3
负载或故障D：I0.4
