RSLogix5000: Writing Tag Values in CSV file and importing

Hello,

I'm currently writing a program that is meant to write values to a specific set of tags. However, when I have a .csv file containing tags, I don't see the option to pre-assign values to the tagsbefore I import them into my program.

Is there any way around this or am I missing something?

you have to use the upload download tool and have a full version of RSlinx. Does not work with Lite version.

You require two different functions.

1 - CSV file, this creates the text file for tag references and descriptions. This does NOT contain any value field.

2 - Upload/Downlaod using OPC. Once you have tags created in your processor, you can call a second function to write data to the tags. This requires an OPC server, as someone else pointed out RSLinx Lite will not work for this.

I have a full version of RSLinx. Any documentation on how I would go about this?

Read the RSLinx manual, there are VBA examples of how to read/write data to a PLC.

cwal61 was referring to a free utility called the Tag Upload / Download Utility.

It's generally installed along with RSLogix 5000, and on my computer it's accessed via Start -> Programs -> Rockwell Software -> RSLogix 5000 Tools -> Tag Upload Download Tool.

I'm still not completely clear on what you're doing; "importing" a tag generally means that you are creating it in the RSLogix 5000 tag database for the first time, rather than writing a value to an existing tag over a network connection.

When you use the Tag Import feature, you're defining the tags only; you provide their scope, their names, their datatypes, and their descriptions. As you have seen, defining a tag does not include a value for that tag.
