(0)  Hi, check: 1. Station addresses: HMI =1, PLC =2, MW = 0 & Baudrates 2. Goto the config menue in TD and check if startadress is 0 3. Create a new project using the TD wizard and do not change the startadress. Let it at VB0 4. Check the cable for the TD if you don't use the TD cable If this works, then all is OK and you can go on creating the progra. Often made mistakes: 1. wrong station adrresses 2. wrong baudrates 3. have a start adrress offset in TD but create a project with wizzard with wrong staradress 4. Overwrite the TD parameter block by PLC program Hope this helps
