大家好！
不知大家有沒有使用過(guò)CP1L-EM40DT-D PLC 或者Ethernet通信模塊 CP1W-CIF41和CCD進(jìn)行通信？這款PLC或通信模塊可否達(dá)到和CCD進(jìn)行接收/發(fā)送數(shù)據(jù)的功能？
現(xiàn)在我有個(gè)項(xiàng)目使用到康耐視的CCD，支持Ethernet通信，康耐視相機(jī)關(guān)于通信協(xié)議的說(shuō)明如下文：
   EtherNet/IP is an application level protocol implemented on top of the Ethernet TCP/IP and UDP/IP layers. It shares its object model with ControlNet and DeviceNet through the common Control and Information Protocol (CIP). This protocol allows the transfer of data and I/O over Ethernet.
      EtherNet/IP uses the standard Ethernet physical layer, and standard Ethernet and Internet protocols (TCP/IP, and UDP/IP) to transmit data. Because TCP/IP is a point-to-point topology, EtherNet/IP only uses this layer for explicit messaging; i.e. those messages in which the data field carries both protocol information and instructions for service performance. With explicit messaging, nodes must interpret each message, execute the requested task and generate responses. These types of messages are typically used to transmit configuration, diagnostic and event data.
     The UDP/IP protocol layer, which has the ability to multi-cast, is used for implicit messaging. With implicit messaging, the data field contains only real-time I/O data; no protocol information is sent because the meaning of the data is pre-defined at the time the connection is established, which in turn minimizes the processing time of the node during run-time. Implicit messages are short, occupying low-overhead, which allows for the time-critical performance needed by controllers.

因?yàn)镃J系列的PLC超出了費(fèi)用預(yù)算，所以我想用CP1H或CP1L系列的PLC完成和相機(jī)之間的Ethernet通信！
不知可否？麻煩各位高手指點(diǎn)一下！
以上，謝謝!

CIF41模塊只能做從設(shè)備，也只接受Host Link協(xié)議
如果你的相機(jī)也是從設(shè)備，那就無(wú)法通訊。。。。。。
