HiWaterlily, I don't think you need process tag type. You can develop you logic in the FB with in the S7 languages (ladder, FBD. STL) or use SCL.Then open any CFC and go in the option menu (from the top bar) and then block type. now Select your FB and transfer it in the CFC block list. Your FB will now be available in the CFC block library. You can then search for your block using the block number . Hope that will solve your problem, Regards, Minhaj |

Hi Minhajie, If I want to use it for about 100 tags, so I don't need process tag? Thanks |

You will need to make a process tag type. This is essentially a template CFC. The procedure is to get the CFC in a position that you are happy with (e.g. working and tested). Then decide what parts (e.g. connections to blocks going on/off the chart) of the CFC you want to customise for each of the process tags (charts) that you are wanting to create. These will be the I/O's you select when creating the process tag type. Then you create an import file. The import file has a number of columns. There will be a column for each of the I/O's you selected to be part of the process tag type. There are also 5 fixed columns: Import mode, Project, Hierarchy, CPU and Chartname. Each row in the import file will create a process tag (chart), so 10 lines will produce 10 charts. See section 6.4 page 73 of this manual. Please note that you will need to use the import / export assistant to make the process tags from the process tag type. This requires a separate license in addition to the usual step 7 licenses. |

HiWaterlily, Well There are two things here now. 1. Make the process tag as described by smiffy. 2. From your logic, I mean only one driver block and a interlock block, I don't think you need a process tag type.You can also use a chart in chart option. What happens is you add a chart from the catalog list in the CFC and place like a normal block in the CFCwhere you want to add your driver block and the interlock block. Then you left click and open that chartadd your blocks and define the chart input and output. You can then copy thischart to which ever CFC you want. Hope this was helpful. Regards, Minhajie

Hi, As I can use process tag tables to edit for later I think using process tag type is better:-) Regards, |
