Micro850 with Delta HMI ethernet/IP

[Nearbyatom]

I'm trying to set up communications between the AB Micro850 and a Delta HMI DOP-107WV. I can get everything working using Modbus TCP. However Micro850 is only limited to 200 tags. I'm running pretty close to it. It looks like Delta software has support for some AB products already (see attached picture), but not the Micro850.



I'm wondering if I can use ethernetIP (controllogix, compactlogix) (use tags). I tried it but it doesn't work. But I might be missing some parameters either on the PLC side, or HMI. I'm not sure. I get a TCP read error 22, no TCP connection.

I'm not even sure if the 2 can talk to each other over ethernetIP. Has anyone given this a shot and made it work before? Let me kow. Thanks!

Where does it say the Micro850 is limited to 200 Tags? (The PanelView800 is limited to 200 tags) but I don't believe the Micro850 is.(But I could very well be wrong, I would just like to read it someplace)

Sorry, You mean Modbus Addresses, yes it does have a limit of 200.

I use the maple system hmi with the micro850/820 with ethernet/ip and there is NO limits (Other than memory) of the number of Tags that can be linked to the Hmi/Plc.

You can use ethernet between the Delta and 850.
Use the Modbus driver - TCP/IP (6 Digits)

We already are using Modbus TCP. However Modbus on the Micro850 has a 200 tag limitation.

I'm trying to use delta HMI and PLC to talk using ethernet/IP to get around this problem.

On the Maple system website, it actually states Micro850 is supported. Delta doesn't have that and i'm relying on that drop down box and maybe one of the selections is similar enough to the micro850. I've been using modbus because it's so universal.

Can you post your setup so I can compare? That's what I want to do but with a delta.

They do have some "Delta Drivers" but maybe not the one you need.

is a specific instruction used in the micro 850 plc? or just by registering the tags in the modbus mapping?

 

[alan777]

sorry for the plc did you use an instruction to define the messaging or just by registering the tags in the modbus section of the PLC?

Hi,

The drivers the author of the thread showed are drivers for the DELTA PLC, these are names of each device series.

In the picture you show the EthernetIP driver, there is on more driver above the one you pointed at, perhaps you could try with the other one.

One suggestions to overcome the problem is to group your boolean tags into UINT or DINT variable like, for example, a word dedicated to machine errors bitwise and use each bit as a boolean variable, assuming you have a lot of boolean variables.

In my opinion there is no reason for the communication between the PLC and the HMI not to work. At least I cannot think of any now.

The EthernetIP protocol for Micro 800 is a little different and limited compared to the ControlLogix protocol, some of the connection parameters are different, and Micro 800 does not support reading several tags in a single request, only one by one, which makes it slower

An option for Micro 800 should appear in that list... but it is not there

But to connect the micro 850 with the HMi delta via modbus, is any instruction required in the PLC? or just mapping the signals in the modbus section to use, any advice would help a lot, thank you very much for your help!
