Hello I just wonder if the problem by accessing the DB is just related to the way the DB is created. By default the Portal Step7 will create DBs as "optimized". But you can create a DB in a non optimized way (S7-300 compatible). In most communication contexts, you must create DBs as non optimized. Did you tried this way? Here an updated link for the communication with S7-1200 and OPC Server http://support.automation.siemens.com/WW/view/en/39960679 At page 10 of the pdf in that link, you will see how tehy define their Data block. |
