Step 5: If you need to set the limit use times of programming card, set by modify value of SMB100 before downloading any block for the default is no limit(the value of SMB100 is 0) Step 6: If you don’t want the the programming block or data block of aimed PLC to be covered, set by modify the value of SMB111 for the default is cover all.
