Description

The Siemens 6ES7315-2AH14-0AB0 is the CPU 315-2 DP central processing unit within the SIMATIC S7-300 modular controller family, built for mid-range automation tasks across discrete and process applications. It executes user programs from 256 KB of integrated work memory and coordinates distributed I/O over its onboard PROFIBUS DP interface.

Its second RS 485 interface operates as a PROFIBUS DP master or slave at up to 12 Mbit/s, supporting as many as 124 DP slaves per station. Programs and data are loaded onto a required Micro Memory Card, which provides maintenance-free, battery-free retention. The CPU draws 24 V DC at 850 mA, dissipates 4.5 W typical, and measures 40 by 125 by 130 mm in the standard S7-300 housing, with an operating range of 0 to 60 °C.

Frequently Asked Questions

Does the 6ES7315-2AH14-0AB0 include a Micro Memory Card?

No. The CPU requires a SIMATIC Micro Memory Card for program and data storage, which must be ordered separately.

What fieldbus does the second interface support?

The isolated second RS 485 interface works as a PROFIBUS DP master or slave at up to 12 Mbit/s, addressing up to 124 slaves.

Which software is required to program this CPU?

It is programmed with STEP 7 V5.2 SP1 or higher (V5.5 SP1 recommended), using languages such as LAD, FBD, and STL.
