Installation & Setup Guidance
When installing the Siemens 6ES7313-6CG04-0AB0, you must use a front connector (1x 40-pole) and a Micro Memory Card (MMC, max 8 MB). The CPU mounts on an S7-300 rack and supports up to 3 expansion units. For power supply protection, Siemens recommends a miniature circuit breaker type C (min. 2 A) or type B (min. 4 A). Ensure the 24 V DC supply is within the permissible range of 19.2 to 28.8 V DC.
Compatibility & Integration
The 6ES7313-6CG04-0AB0 communicates via MPI and PROFIBUS DP. It can serve as a DP master (integrated) and supports up to 4 additional DP masters via CP modules. The CPU is compatible with STEP 7 programming packages V5.5 + SP1 or higher, or V5.3 + SP2 with HSP 203. It integrates seamlessly with other S7-300 modules, FMs, and CPs (FM up to 8, CP PtP up to 8, CP LAN up to 6).
Selection Guide & Purchasing Advice
Before purchasing the Siemens 6ES7313-6CG04-0AB0, verify that your system requires a CPU with integrated I/O and DP. The MMC (not included) must have at least 128 KB capacity; we recommend a 8 MB MMC for larger projects.
