Pump Posts: 6 Rating: (4)	Hi, I have a stupid question ! When i check my "variables" PLC i have two columns "Visible in the IHM" and "accessible from IHM" [img]http://img69.xooimage.com/files/e/3/d/test-316e8f5.jpg[/img] The first column means that one can read the value in the IHM and the second columns means you can write a value to this variable ?? And so if it's ok, i can't write a value in DB variable ? Because i have just the column "Visible in HMI". Sorry for my english.... and i hope someone can help me a little bit :) Attachment test-316e8f5.jpg (539 Downloads)

Tweety Posts: 3037 Rating: (192)	Hello Pump, You need the property "Accessible from HMI", then you can change this value in the Runtime. You can see more information about these properties in the following manual. See chapter 9.1.2.6. STEP 7 Professional V11.0 SP2 Tweety

Pump Posts: 6 Rating: (4)	Editing properties in a PLC tag table To edit the properties of one or more tags, follow these steps: 1. In the project tree, double-click the PLC tag table that contains the tags. The PLC tag table opens. 2. Change the entries in the columns. I don't find the PLC tag table :'(.... Edit : OH !! It's ok i found it !!! Really thanks you :)
