Description
The Siemens 6ES7315-6FF04-0AB0 is the CPU 315F-2 DP, a fail-safe S7-300 CPU. Siemens's data sheet describes it as a fail-safe module with an MPI interface and a second interface for PROFIBUS DP master or device, 384 KB of integrated work memory, a 40 mm module width and a 24 V DC supply. The program is held on a Micro Memory Card. Siemens's data sheet marks it as a spare part.
Application: PLC controller
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7315-6FF04-0AB0 used for?
It runs a machine's standard control program and its safety functions, such as emergency stops, guards and light curtains, in one CPU, with fail-safe I/O on the rack or on PROFIBUS DP. A failed F-CPU stops the machine until it is replaced. As a fail-safe CPU its safety program and configuration must be checked against the replacement before it goes back into service.
Key features
- Fail-safe CPU for standard and safety programs
- 384 KB integrated work memory
- MPI and PROFIBUS DP master/device
- 40 mm module width
- 24 V DC supply; program on a Micro Memory Card
- Siemens lists it as a spare part
