Hello Istael; There are many networks and functions that will allow 2 S7-1200 CPUs to communicate with each other. The type of exchange you choose will depend mostly on the number of bytes you can send and receive between the CPUs with a single instruction and thé type of network you Will use To connect thé CPUs. The document that is included in the following link describes all possible exchange functions between the 2 CPUs you select: CPU-CPU communication with SIMATIC controllers (compendium) https://support.industry.siemens.com/cs/ww/en/view/20982954 The simplest functions to use are PUT and GET, over a Profinet connection (they are designated "S7 communication" functions). They are the simplest because only one of the CPUs (the client) has to be configured and programmed. The other CPU (the server) acts as a passive station. You are limited to 160 bytes per Get or PUT functions; the following Application Example shows how you can multiplex PUT and GET to sen and receive a greater number of bytes: How do you program the "GET" and "PUT" instructions in the user program of the SIMATIC S7-1200 CPU in order to transfer more than 160 bytes of data? https://support.industry.siemens.com/cs/ww/en/view/65975617 Hope this helps, Daniel Chartier |
