PCS7 8.1 SP1 Hello, I made an example project and put it into runtime. What I notice is that for motor and valve blocks, possibly more blocks...an text with "Error" shows up under the "Command". Normally, "Start" or "Stop" or "Open" or "Close" should be listed, but it's showing error. The other text like "Automatic", "Manual" mode is OK. Can somebody tell me what the problem could be?See attached image 1. Project original created with 8.0 SP1 2. Full compile + Full download (to PLCSIM) 3. OS full compile on single station Blocks can be controlled, also the button which shows: "Error" can be clicked as well and than the motor/valve is controlled.
EDIT: If I open the block in CFC and check parameter: StartMan, I can fill in a text for text1. If I do that, and do a full compile with reset, than the configured text is shown. But when the textfield is blank, the system should take the default value, but it just shows "Error"... |

Hello all, Out of frustration, I created a new project in 8.1 SP1. Put everything in runtime and had no problem. I actually found the difference...It's in the start value of the tag: StartMan#string1. In 8.0 version, running in 8.1 SP1, the start value is "1", in the new project it is set to "81". 81 is an empty text in the text library, "1" is the place of the text: "Error". So, that's very strange...Harry, your right about deleting the "Error" text in the text library. When nothing is filled in for the index number...it will take the default value. But this is not the solution... What I also tried in the "old" project was to copy the AP library 8.1 so the blocks are all updated...no success. At last I tried to convert the WinCC project under WinCC->Tools->Convert project data....no success.. I quickly checked another V8.0 project in the actual plant. StartMan#string1 is set to "0". So a little confused now, why would 8.1SP1 set the value to "81". |

Hello, I checked the 8.0 sp2 project we have here and there the ID is set to "0". The text library in 8.0 sp2 is different, because id 81 has been assigned with a text value. Why is the value not set to "0"? How does the system set the ID for that specific attribute StartMan#string1? ID 81 is a strange number...so why not "0". |
