Siemens 6AG1 315-2EH14-2AY0 Simatic CPU Module

Siemens SIPLUS S7-300 CPU 315-2PN/DP, E-Stand 4, order number 6AG1315-2EH14-2AY0, is a rugged SIPLUS extreme CPU module for the SIMATIC S7-300 automation family and EN50155-compliant transport applications. It provides 384 KB of work memory and supports two network interfaces: a primary MPI/DP bus at 12 Mbps for device communications and a secondary Ethernet PROFINET interface with an integrated 2-port switch for PLC-to-PLC and device networking, with a Micro Memory Card required for program and data storage. The module is rated for operation in harsh environments with EN50155 compliance and a wide operating temperature of -25 to +70 °C, reflecting its design for extreme conditions in rail and other transport settings. This CPU plugs into a SIMATIC S7-300 rack and preserves compatibility with existing S7-300 I/O and software ecosystems while enabling distributed control and advanced networking through PN/DP.
