reading from Data table in Visilogic

[kibomaestro]

Hello there,.

I am working in Visilogic and using V570 PLC.

Can someone tell me how can I know memory location of first element in Data table?

Is there any sistem integer for index in Data table?

I believe the answer is that the Information in a data table is not accessable directly. You need to read the information you want out of the data table using the read row or read collumn function blocks.

Just open datatable and place mouse pointer over cell you want to get memory allocation. It shows type of register, length and allocation (FLASH: ## or RAM:##).

Hi,

Attached is a complete example (VisiLogic application, Help PDF and VB code) of how to access Data Tables.

I hope it will be useful!

keep in mind that using the direct cell location will method will not shift the access point if a new column is inserted before the cell being addressed.
