Hello, PCS7 7.1SP1 XP Pro SP3 Strange problem: Last thing I did was setting the marker for create debugger info for SCL source to monitor. Since then when downloading changes (using download button in cfc chart) system hangs and displays the error code: Message 0x0 No text in resource DLL "s7jcomfb.dll". available : 0xFFDF_4022: [S7DOS] No reply to STEP 7 message frame. extra info when looking in error history: Function = c_lds7xs, error location= 13 Sometimes I can download the program, and for a moment signals are working.If Iwant to start a motor or something, I don't see any response. This when I'm in test mode in cfc and also in runtime... The things I did: - deselect the create debugger info in scl, maybe that was the solution, but it wasn't - hard reset on plc, downloaded hardware configuration and compiled/downloaded everything from start - cleared in online mode: system data of PLC - reorganisation of project I only worked in my custom SCL block, downloaded/changed numberous times, all of the sudden this stupid error came up, I can't do anything, the whole system won't work! When I succeed in downloading (happens when I compiled only and then download, the PLC goes to stop after downloading only the changes. This wasn't always like this. When I look in the hardware diagnostics the following message appears, which I didn't get earlier: Multiple OB request errors caused start information buffer overflow Cause: cyclic interrupt clock pulse generator 6 and some extra about priority class 12 and interrupt DB35 EDIT: By the way, I looked at a previous post with almost same error. I checked my computer for virusses and Norman responded with this: C:\Program Files\Siemens\Common\BIN\DAClockPropesp.lng -> Trojan W32/Suspicious_Gen2_AKSDH(). File was moved to quarantine....maybe, hopefully someone recognizes this...... Hope you guys can help.... Best regards, |

Well, that was not a answer I expected... I'll try to retrieve my backup project. Thank god I make a backup everyday... If that doesn't work, I have to restore my image from the PC, maybe that is corrupted... Question remains how this was started.. The only non standard action I executed, was downloading the SCL source in the PLC after compiling....Compiling an old version of the SCL source didn;t work either.. So maybe I have to delete the whole block, download without, compile again... Take a lot of time because I use the source 20 times.... I'll try to figure it out.. Thxx EDIT** Well, I got my backup and changed everything like it was. The SCL source from backup project is manually adjusted, taking no risks.. Everything seem to be ok. Could it be that when you compile the SCL source in SCL editor and then download it to the BLOCK folder (program), that there can be some inconsistency? Because you overrule the CFC charts basically. That is the only thing I can think of. Or maybe the virus that was found...if it is even a virus, maybe a false detection. |

Hell Phantom, Normally the procedure is like this: - compile SCL source - In CFC->Options->Block Types-> Update block (if there are big changes) - Compile CFC and download to PLC What I accidently did was: - Compile SCL source - Download SCL source to Block (in SCL editor) - In CFC->Options->Block Types->Update block - Compile CFC and download to PLC Maybe there is some inconsistency between the block in PLC program and block in CFC.... Do you understand what I trying to say? Thanxx |
