Regarding the question, to achieve PLC-to-PLC communication using TelePACE Studio software, you can follow the steps outlined in the TelePACE Studio training manual (MSTR block). Additionally, for the specific scenario you mentioned (Scadapack357 to Scadapack32), you will need to create sample PLC programs for both ends and configure the necessary settings for communication. Unfortunately, without further details about the specific requirements and configuration, it is difficult to provide a specific answer.
