This is the third episode of the Opto22 groov CPU Tutorial. This time we will explain the MMP Memory Mapping concept of the groov CPU, then convert from MMP addresses to Modbus TCP, and finally I will show you how to access IO module data via Modbus TCP. Let’s get started! MMP? OptoMMP is a memory mapping protocol based on the IEEE1394 standard. We can use this protocol to create … Continue reading Opto22#Let’s get the IO Data from Groov EPIC via ModbusTCP
