Hi all. I know in codesys the values of network variables can be exchanged between different PLCs in a network https://help.codesys.com/webapp/_cds_f_networkvariables;product=codesys;version=3.5.14. my goal is to connect a codesys plc with a siemens et200sp plc. does anyone know if there are any blocks to use in tia portal to exchange network variables with codesys? My knowledge in tia is very basic. A concrete example would be a great starting point. I found this example by googling : https://sourceforge.net/projects/easynetvars/files/NetVarsStep7/ But I didn't understand anything. Every help is appreciated. Thanks |

Hello ebcz; Hoping this will help you, it explains how to program communications functions for UDP exchanges for new generation CPUs, S7-1200 and S7-1500: A sample program and documentation for Open User Communications can be downloaded. - How do you program the TSEND_C and TRCV_C instructions for open user communication over the integrated PROFINET interface of the S7-1200/S7-1500 CPU? https://support.industry.siemens.com/cs/ww/en/view/67196808 Hope this helps, Daniel Chartier |
