Hi jord41,
Simio loads the bound tables once during the initialization in the Simio tables.
Data access requires a lot of computing time. (More for writing as reading).
I see that you only have 1 column of integer values.
My recommendation is that you do not import the table into a Simio table. It's best to create an integer or real state of type vector.
Then you use e.g. the Read-Step or the ExcelRead-Step. In conjunction with a timer or the sample example loop of GFurtado you can load the data at intervals. I think that this could be a solution. At least that's how I would do it if I had to work with real-time data.
Normally, such real-time data is written to a SQL database by a PLC or something like that. Then you can use the SQL steps anytime in Simio.
Best regards
Pascal
