Hello Satya; At this moment you seem to need general information on communication possibilities with a Siemens S7 PLC (in this case, i am still discussing a S7-300 or S7-400, not S7-1200). Start your weekend with the following links, They should give you a good head start (and possibly a good headache as well): For communication processors and Siemens “native” protocols, see these manuals and FAQs: Configuring Hardware and Communication Connections STEP 7 Communication with SIMATIC - Siemens
- FAQs on Profibus connections and communication functions:PROFIBUS S7-300/400 CPs -- Configuring and programming communication -- Using communication blocks More available protocols (licenses to be purchased, downloaded and configured): Modbus RTU Communication Module Manual, Modbus master software, Modbus protocol Depending on the protocols supported by the PLCs you want to connect to, OPC might be a workable option: OPC (with Simatic Net licenses): SIMATIC NET PC software Industrial Communication with PG/PC Volume 1 - Basics System Manual SIMATIC NET PC software Industrial Communication with PG/PC Volume 2 - Interfaces Programming Manual You might need gateways between Siemens protocols and certainprotocols supported by your other PLCs, for example if you need to interface a Siemens CP 343-1 Ethernet processor with a Controllogix Ethernet/IP module, Siemens suggests an Echochange gateway: There are many other issues to be refined when you have started your communicationsurvey. Youshould see now that it is a must at the beginning of your project, before you start defining hardware and programming communication functions. Hope this helps, |
