PLC采用RS-485通讯方法控制变频器
这是使用得普遍的一种方法,PLC采用RS
串行通讯指令编程。优点:硬件简单、造价
,可控制32台变频器。缺点:编程工作量较大
4、 PLC采用RS-485的Modbus-RTU通讯方法控制变
频器
RS-485端子利用Modbus-RTU协议与PLC进行通讯
。优点:Modbus通讯方式的plc编程比RS-485无协
议方式要简单便捷。缺点:PLC编程工作量仍然较
大。
5、 PLC采用现场总线方式控制变频器
三菱变频器可内置各种类型的通讯选件,如
用于CC-Link现场总线的FR-A5NC选件;用于
Profibus DP现场总线的FR-A5AP(A)选件;用于
DeviceNet现场总线的FR-A5ND选件等等。三菱FX
系列PLC有对应的通讯接口模块与之对接。
优点:速度快、距离远、效率高、工作稳定
、编程简单、可连接变频器数量多。缺点:造价
较高。
6、采用扩展存储器
优点:造价低廉、易学易用、性能可靠 缺点
:只能用于不多于8台变频器的系统。
