Hello, experts! I've found the strange problem: - one simple sequenser (2 steps, second step with supervision), after source compilation the FB and iDB in Simatic Manager are signed with small yellow triangle; - GRAPH FB compiled with option of supervision errors acknowledge; - calling it from OB1, engaging step withSV- everything is ok, there is a proper message; - puttingtwo instances of GRAPH FB into CFC chart; - compiling; - CFC says that old iDB causes an error; - deleting old iDB; - compiling; - CFC says ok, but small yellow triangles disappear from iDBs, and they have no messages inside, FB still has a small yellow triangle; - downloading to PLC-SIM; - CFC says ok; - engaging step with SV of the first iFB - message "no entry in text data base"; - engaging step with SV of thesecond iFB - no message if the first one is active, the same message if the first one was acknowledged properly; - closing CFC; - opening FB and modifying the iDBs using option "Modify/adapt instance DB number"; - iDBs now have small yellow triangles and messages inside them could be edited; - downloading them into PLC-SIM; - engaging step with SV of the first iFB - message with text and faulty step #; - engaging step with SV of the second iFB - no message if the first one is active, the same message if the first one was acknowledged properly; - CFC can not go online any more - iDBs were changed... In archive attached there is a project with completed iDBs substitution - "three small yellow triangles" phase How tosolve this problem? How to get the proper unique messages from some amount of GRAPH iFBs in CFC? And what do the small yellow triangles mean? Also I want to know why in CFC chart one of the iFBs blocks contains bright-green field with OB number, and another - with dark-green? AttachmentGraph_cfc_msg.zip (114 Downloads) |

Hello, the small yellow triangle which is signed by the FB in the SIMATIC Manager is a mark for prozess diagnostic. See also the information in the FAQ (enclosed link), which can be useful for you: http://support.automation.siemens.com/WW/view/de/5608787 With best regards |
