It provides two Industrial Ethernet ports at 10/100 Mbit/s, connecting a SIMATIC S7-1200 and up to three further nodes to the network. The module is actively produced and carries an MTBF of 273 a, indicating reliable long-term operation in harsh conditions. Rated IP20 and compliant with EN 61000-6-4 (Class A) and EN 61000-6-2 for industrial EMC, it fits standard control panels without additional sealing. Dimensions are 75 x 100 x 45 mm. As a SIPLUS variant, it is factory-tested to the extended temperature range and comes with conformal coating. For BOM freeze or AVL review, the active status means it can be specified without deviation planning. ## Fit & Integration Mounts directly on a DIN rail; the 45 mm depth leaves clearance in shallow enclosures. Connects a SIMATIC S7-1200 and up to three further nodes to Industrial Ethernet. Designed specifically for the S7-1200 family; integrates via the PROFINET interface. The conformal coating protects against condensation, dust, and airborne diesel/oil droplets, per EN 60721-3-3 Class 3S4.","metaTitle":"Siemens 6AG1277-1AA10-2AA0 SIPLUS CSM 1277, -40..+70°C","metaDescription":"Active Siemens SIPLUS NET CSM 1277 compact switch module, -40 to +70°C with conformal coating, 10/100 Mbit/s, MTBF 273 a, IP20.
