The Siemens 6ES7147-6BG00-0AB0 is a PROFINET IO module from the ET 200SP family—M12‑connected, with an integrated two‑port switch. It carries standard PROFINET protocols: ARP, DCP, MRP, and LLDP, plus diagnostic alarms and a group‑error LED (red/yellow SF/MT). No PROFIsafe onboard, so keep safety CPUs on a separate F‑module.
What the PROFINET protocols mean for your network
ARP, DCP, and LLDP let the module self‑identify on the network and be located without manual IP setup—handy when a line engineer swaps a failed unit and the engineering station picks it up automatically. MRP enables media redundancy for ring topologies; with MRP enabled, a single cable break won’t drop the IO device. All these run over the integrated 100BASE‑TX switch, so you don’t need an external switch for line‑daisy‑chaining up to the specified cable length of 30 m unshielded.
Physical footprint: 60 mm wide × 175 mm high × 49 mm deep, roughly 910 g. Mounts on the ET 200SP baseUnit; the M12 connectors point forward, leaving side‑to‑side space for adjacent modules. Power consumption 6.5 W typ. at 24 V DC. Current draw at 60 °C is 3.9 A maximum—factor that into your backplane supply budget.
