Starting my Project and having issues with the PUT GET blocks between the 2 PLC's, I think everything is done correctly(but obviously not) i.e 1; PLC protection, connection mechanism is picked on both PLC's. 2; Data Blocks, properties, attributes, optimised block access not clicked on both. 3; IP addresses different and subnet's the same. 4; PLC Connection ID 100 and 101 respectively When I use an input to switch an output in the Data Block it shows it has changed state in the Data Block on the same PLC but it's not being transferred to the second PLC. I've went back to basics and just used a simple input, output config on the Data Blocks i.e on PUT on PLC1 ADDR_1=P#Q0.0 Byte 10 and SD_1 P#I0.0 Byte 10 and on the GET on PLC 2 ADDR_1=P#I0.0 Byte 10 and RD_1 P#Q0.0 Byte 10 with still not changing on the other PLC I'm adding screen shots of the project and I'm also using a PLC Sim to test if that makes a difference Anything else you may need let me know, any help much appreciated. Thanks in advance Attachmentpng2pdf.pdf (424 Downloads) |

Hey again added in the status, error and done outputs that you suggested and it seems the ERROR is always true and the STATUS is 001 which indicates a comm. problem. Diagnostics on the blocks brings me to the Devices and Networks page with both PLC's in red and the online status is dead in the connections information as seen in the screen shots. Not sure if this is because its a SIM program running it or if that's where the issue lies, but all protection allowances are allowed and both optimized block allowances are not ticked so now I'm really not sure whats left. Is there a Main OB1 optimized block I need to de-tick??? Attachmentpng2pdf.pdf (337 Downloads) |

No, if you look at the last post I put up with the pictures it gives a proper picture of me redoing it as per your suggested. |

Hey dp, this is a little easier for sure, this is just a quick example to find out where I'm going wrong as I have no experience with Siemens so I can go off and start my project. And thank you very much for all your time I'm sure you have better things to be doing Attachment1500 test3.zip (279 Downloads) |
