Mitsubishi Q and SMC JXCD1 Devicenet module
Embblomgren posted a topic in MitsubishiHi guys. On our company we got several different PLC system but right now I´m focusing on a Mitsubishi Q-system with device-net master QJ71DN91. We are going to make communication with SMC-JXCD1 controller for a actuator. But I have no experience with DeviceNet and unfortunately there is no files, functionblock, or program examples what I can find. Not even Mitsubishi or SMC had some for these two together so I turning the Question into this forum instead😊 Previously I´ve used profibus on a fx3U system and FX5U-Simple CPU communication protocol to talk with slaves in a network. I got on hold of some old document from Beijer from where I got 3 functionblocks for devicenet. 1.DnInitiateQ 2. DnSupervisorQ 3. DnDataQ 4. DnMessageQ So maybe I can have some help from these but I´m still not sure how to send/receive information to the SMC-nodes. I´m a little confused about if I should use the master with I/O communication or master with explicit messages? The later I haven´t even heard of. I was only thinking about creating array of word to receive and send info to the nodes. But my knowledge of this communication protocol is very low. Anyone know´s how to get me started? Or can provide some kind of example in GX IEC or GX works.
