CPU 1515-2 PN with safety and redundancy
The Siemens 6ES7515-2FM01-0AB0 is a SIMATIC CPU with integrated PROFINET, supporting PROFIsafe, MRP manager, and multiple programming languages including LAD, FBD, SCL, STL, and GRAPH.
Temperature rating and physical fit
Rated for a -40 to 70 °C ambient range, this CPU tolerates unheated cabinets or rooftop installations without additional climate control. Dimensions of 70 mm wide, 147 mm tall, and 129 mm deep fit standard 70 mm DIN rail enclosures.
Network integration
The onboard PROFINET interface handles 100 Mbps, MRP (manager/client) for media redundancy per IEC 62439-2 Edition 2.0, and supports DCP, DNS, LLDP, SNMP, DHCP, and MODBUS TCP. MRPD is available when IRT is active.
Programming and fail-safe capability
Programmable in LAD, FBD (both with fail-safe extensions), SCL, STL, and GRAPH. Process image handles 32 kbyte inputs and 32 kbyte outputs. Forcing is supported in standard logic; PROFIsafe enables safety communication over the same PROFINET cable.
