bahman,

To add a VAT to your project, in the 'blocks' folder of the PLC, select 'Insert' from the menu, then 'S7 Block', then 'Variable Table' or you could right click anywhere in the block folder window, select 'insert new object', 'Variable table'.

Once you have your VAT table up, all you have to do is write down the addresses that you wish to monitor, then click on the glasses symbol to go on line.

If you wish to monitor a lot of I/O, I would recommend that you monitor, them as words, not individual bits.

You can also - monitor-modify variables , then save the table you create when you finish - one and the same thing.
