Hi davide_maffei, with Date_And_Time it is not that easy, because it uses the BCD format. If possible use DTL instead, it is more easy. Is it possible for you? Here is some documentation but not really a list: https://github.com/plcpeople/nodeS7/blob/master/README.md I am testing it with Date_And_Time at the moment. Since now I only had success with DTL. Best regards! |

Thank you bergmanu! I tried also with DTL but I cannot read the whole variable using the same address posted in my first topic. In this case I have to read the variable as an Array splitted in the USInt element Year,Month,....etc ? Best Regards

Hi JDarius,
I attached an example which uses the IOT2000 time as timestamp. If you synchronize your PLC and your IOT with the same ntp server, this should be a good way.
Yes this would trigger every second, if the timestamp format changes every second.
S7 connection is no problem with PLCSim Advanced. So this should work, but I have to check this too.
Do you have connection to your PLCSim Advanced? Ping is possible? If not make sure that you selected "Virtual Ethernet Adapter" in your PLCSim settings. Are there some errors displayed by node-red? AttachmentData+Timestamp.txt (1689 Downloads) |

Hi Hugo, have you tried using "db1,X0.0" instead of "db1,bool0" ? Best Regards, Tiago Machado |

To install packages using npm you need an internet connection. |

Do I need to give this command in a specific directory, or can I run this in root? |

Hi all, I'm trying to get a boolean value of a level sensor out of a S7-1200 PLC using this guide. Could anybody please confirm if I'm doing this correctly? I can't seem to get the IOT2040 to create the file with the variables. [snip] Thanks in advance, Connor AttachmentScreenshots.zip (1139 Downloads) |
