Hello ralaisa; The following FAQ will give you access to most required information on the subject of Modbus TCP implementation on a S7 PLC: How can you establish OPEN MODBUS / TCP communication from a SIMATIC S7 and where can you find further information? You can either use a S7-300 CPU with integrated Profinet ports (example, a S7-317-2PN/DP) along with the OpenModbus TPC license for PN CPUs, or select one of the CP 341 models accepted for Modbus (see the attachment, taken from the Siemens Industry Mall site) along with the Open Modbus license for CPs. For supplementary information, search the forum site (use the Search box at the right of this page) there have been a number of threads on the subject, along with FAQs and manuals. Hope this helps, Daniel Chartier |
