Hi 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.
