PLC与变频器防爆箱之间的接口问题

1、需要控制系统在设计时采用很多硬件,价格昂贵
2、现场的布线多容易引起躁声和干扰
3、PLC 和变频器防爆箱之间传输的信息受硬件的限制,交换的信息量很少。
4、在变频器防爆箱的启停控制中由于继电器接触器等硬件的动作时间有延时,影响控制精度。
5、通常变频器防爆箱的故障状态由一个接点输出,PLC能得到变频器防爆箱的故障状态,但不能准确的判断当故障发生时,变频器防爆箱是何种故障。

二、使用USS协议的步骤:
天天斗地主1)安装指令库后在STEP7-Micro/win32指令树的/指令/库/USS PROTOOL文件夹中将出现8条指令,用它门来控制变频器防爆箱的运行和变频器防爆箱参数的读写操作,这些子程序是西门子公司开发的用户不需要关注这些指令的内部结构,只需要在程序中调用即可。

4)用变频器防爆箱的操作面板设置变频器防爆箱的通讯参数,使之与用户程序中所用的波特率和从站地址相一致。
天天斗地主5)连接CPU和变频器防爆箱之间的通讯电缆,为了提高看干扰能力zui好采用屏蔽电缆。
