A1A10000350.00M控制板

问：CPU313C，请问数据块DB的掉电保持怎样设定啊？

答：DB块默认是掉电保持的。如果要取消只需要在DB块属性中将非掉电保持打勾即可。

问：请问一下，在编程时程序里同时有两个线圈，两个线圈前面都有不同的条件时接通，我在监控时，看到前面一个通了，后面一个条件不对，线圈没有通，输出来时线圈显示不通，请问是不是在程序里所有的线圈只能有一个，不能有两个或多个，谢谢

答：我在监控时，看到前面一个通了，后面一个条件不对，线圈没有通，输出来时线圈显示不通－－－－程序有双线圈错误。这是因为PLC是从上而下，从左而右扫描。在扫描到前面一个线圈时因为条件满足所以在监控里看到第一个线圈是通的，在扫描到第二个线圈时因为条件不满足所以在监控里看到第二个线圈是不通。这是因为PLC是从上而下，从左而右扫描。所以后的输出是以第二个线圈的状态为准的。

解决这个问题可以M位做中继。

比如现在这个线圈的地址是Q0.0。可以用在用M0.0代替第一个线圈，用M0.1代替第二个线圈。然后用M0.0并M0.1输出接Q0.0。

1、从上位机写整型数INT或实数REAL到PLC，首先该数值需包含以毫秒为单位的时间值，在写入PLC的数据存储区后，利用ITD（Integer to Double Integer）或RND（Real to Double Integer with Rounding Off）将该值转换为双整形，然后将该值写到类型为TIME的变量里，在程序中调用FC40，将TIME转换成S5TIME即可。

2、从上位机写WORD到PLC，首先该数值需包含以某时基为单位的时间值，在写入PLC的数据存储区后，用Word Logic下的WOR_W指令将该值与其时基相或，再利用MOVE指令将得到的数值写入S5TIME类型的变量中。

3.如果使用WinCC作为上位软件，或上位软件支持32位带符号浮点数，可以从上位写32位带符号浮点数到PLC中定义为TIME的变量，然问：S7300 cpu315-2D，上位机PC通讯模块CP5611，故障现象：5611无法与CPU通讯，wincc检测不到数据，不能工作。

答：首先检测以下几方面问题：

1、在Step7中的PG/PC中设置是否指向cp5611（MPI）？

2、dp接头接线是否正确（上面的终端电阻是否设置正确）？

3、在WinCC中的通道设置是否设置好（诸如是否建立MPI通道，MPI通道中的参数设置是否正确，例如站地址为2，插槽号位2）？

以上若无问题的话，应该能正常连接。

后在程序中调用FC40，将TIME转换成S5TIME即可。
