Hello, im new using s7-300 and i want to do an indirect adressing:
program in AWL that reads its DB1 content through indirect adressing. This suppose that in the DB is logged contents into 10 words of a table and you want access to any position in that table by EB124 with a 1 sec pulse, and that AB124 is represents the contents of the table.
First i need to Open DB1 by OPN DB1 no?
then load ar1 with LAR1 P#DB1.DBW 0 an then i dont know how to continue with it...
thx for u helping
