released. For new modules or newer versions of modules, we reserve the option to

add to the manual a product information containing the current information on this

module.

SIMATIC Outdoor CPUs

CPUs with the order number 31x-xxx 8 x-... are SIMATIC outdoor modules that are

suitable for use in a wider range of ambient conditions (see also Reference Manual

Module Data).

The range of functions and technical specifications of these CPUs are the same as

the ”standard” CPUs. For that reason, the SIMATIC Outdoor CPUs will not be

referred to separately again in this manual.

Important Information

Alterations from Previous Version

The following changes have been made from the previous version of the manual

(S7-300 Programmable Controller, Installation and Hardware (order no.

6ES7 398-8AA02-8BA0), Edition 1):

New CPU:

– CPU 314 IFM (as 314-5AE03 but with extra slot for memory card)

CPUs 31x-2: the description of the configuration and parameter assignment

frame is no longer part of this manual. Instead, you can find it on the internet at

http://www.ad.siemens.de/simatic-cs under article ID 996685.

The list of OBs, SFCs/SFBs and SSL IDs is no longer in this manual but rather

in the instruction list

New CPU features:

– New SFCs: SFC 23 “DEL_DB” and SFC 81 “UBLKMOV”

– Clock synchronisation on MPI as master/slave

– 32-byte consistency for communications

– Connection resources can be reserved for PG/OP/S7 basic communication

(except for CPU 318-2)

– CPU 315-1: user-defined address allocation

Agreement for CPU 314 IFM

The CPU 314 IFM is available in 2 versions as follows:

with slot for memory card

(6ES7 314-5EA 10 -0AB0)

without slot for memory card

(6ES7 314-5EA 0 -0AB0)

All details in this manual apply to both versions of the CPU 314 IFM unless explicit

reference is made to differences between them.

Standards, Certificates and Approvals

The S7-300 programmable controller meets the requirements and criteria of

standard IEC 1131, Part 2. The S7-300 meets the requirements for the CE mark.

Approvals for CSA, UL and FM have been granted for the S7-300.

See Appendi x A fo r detailed information on standards and approvals.
