Hello Paulo; Fron your attached picture we can see you have no MicroMemory Card (MMC) slotted in the CPU. Do you have ccess to a MMC for this CPU? Such a MMC is required for the CPU to operate, it acts as Load Memory for the PLC: this is where programs and configuration data from your programming software is copied when you download to the CPU. For more infrmation on the MMC as Load memory, please open the following link: MMC as Load Memory for S7-300 CPUs For MMC part numbers for your particular PLC check the file attached to this FAQ document: Which memory cards can you use with an S7-300 CPU? The attached picture below illustrates the points discussed. Hope this helps, Daniel Chartier |
