能否通过非FieldPoint的实时终端控制 cFP-180x ?
硬件: Compact FieldPoint>>Controllers>>cFP-1808, Compact FieldPoint>>Controllers>>cFP-1804
问题: 用户拥有cRIO或者RT PXI的RT控制器,同时希望通过Compact FieldPoint 1804 or 1808来进行数据的输入和输出。对于非FieldPoint的实时控制器,该项功能能否实现?若能,该如何进行操作。
解答: 该方案可行。通过 Modbus协议可以使用cRIO或者RT PXI的RT控制器来控制cFP-180x 。用户必须下载安装 Modbus Library 。详细信息可以参照文档: KnowledgeBase 3W38J8S9: Where Can I Find the Documentation for Using Modbus with the cFP-180x?
