Hello, I’m trying to pull a DINT to display, and a momentary button to reset value. I am using a micro820. I’ve heard modbus is the way to go. but i’m confused because tags in the 820 are not coil 1,2, etc… so I don’t know how that converts to a modbus address such as 3139 etc,? any help would be greatly appreciated ---

You have to deliberately set the correspondence between the internal tags and Modbus addresses. (In Connected Components Workbench.) ---

I tried exporting the config from ccw and but when i import into ignition it does nothing ---

Its been a while since I messed with my micro850, but I think I configured the modbus address in CCW, then added the PLC as a device on the gateway webpage. Then the OPC Item Path should just be `[DeviceNameHere]modbusMapping`, for example `[WeimaWoodchipper]C2` [Modbus Addressing AB Micro850 - Ignition - Inductive Automation Forum](http://forum.inductiveautomation.com/t/modbus-addressing-ab-micro850/19070) ---

Did the Modbus configuration get exported to the PLC? Is the PLC set to allow remote connection? ---

I don’t see a remote connection setting. I’m currently remotely accessing via ethernet. And i downloaded after mapping not sure what else might be required to export to plc ---

I can’t think of anything else, I don’t have the micro850 PLC in use anymore so I can’t check any configurations ☹ Maybe someone else with more experience can chime in. ---

You are going to want to configure the DINT in the 4xxxxx range, not the coils range. It’ll occupy two holding registers, not 32 coils. ---

andrews, Have you got this sorted out? If not I can send some config screen shots on how to make this work. ---

I have not. That would be greatly appreciated. It’s been so troublesome I’m ready to spend the extra money and get a micrologix 1400 for one photo eye . Again thank you very much. ---

Ok lets take it from the top. First in the Micro820 Modbus mapping - Your count\_value needs to be at address 400001 this is where holding registers are mapped in Modbus. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/5/2583b0371bb65aef1dbca454fddca070f978b3e5.png) Next Ignition In the configuration for the Modbus TCP driver under advanced properties check “Reverse Word Order”. The rest of the default settings should be fine. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/7/e72f8d12917fb47a13e641b0973eb2051bfe9c0d.png) Now go the the “Addresses” for the Modbus TCP driver ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/9/f92fcd1aa9cc56e7890bc1491e12948ed38eb4a2.png) Reset\_Count is a coil and Count\_Value is a holding register. The Prefixes I used below are arbitrary , call them what you want but they will be used in your Tag. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/1/31ee77834269fe7bfc0ae86cf544fad00789234a.png) Finally define your tags, using my example I called the Modbus TCP Device “Line5” so the OPC Item Paths for your tags will be: Reset\_Count = ns=1;s=[Line5]DO1 Count\_Value = ns=1;s=[Line5]Dint1 Notice the prefixes we defined under Addresses. This should get you up and running. I left out the explanation of the why’s for a couple of these steps to keep this short and just get you going. Let me know if you want more information or run into issues. ---

Okay still no luck. I checked reversed word order and below are pics of my configs. I also added pics of how it looks when i drag the mapped address to the folder in the designer. the only difference is the dragged ones look like `ns=1;s=[Line5Counter]DINT1` ![Capture](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/f/bfc657234e811317d9e1fa1cc4896de359fe5a24.png) ![Capture1](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/2/525d0f90a43278de094c7e897e7aa503470fda8d.png) ![Capture2](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/0/50626eca7bb93021adbd5cac551ebcd07307c838.png) ---

Why does your OPC Item Path start with “Total =”? ---

You misinterpreted what he is saying. The lefthand side is just the example tag name. Your OPC Item Path should only be the `ns=1;s=[Line5]DO1` part. [Next page](https://forum.inductiveautomation.com/t/need-to-pull-dint-and-reset-from-micro820/48073.md?page=2)
