Dear Wüstenräuber, I have restarted the PLCs by tricking them into downloading the hardware again, so that the installation won´t stop. I have observed that whenever I make a petition to read/write I get directly an error in the module and no busy or done is ever activated, they are always 0. I attach the chart. It is the one giving me the problem. AttachmentUOperate.pdf (307 Downloads) |

Hello Thanasis, there is a hotfix available regarding the communication lock up after restart. You can order it at it4.industry@siemens.com by telling them the license number of the Modbus library. Regards, Kaulquappe |
