Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the relevant information is not taken into account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Preface 1
Purpose of the manual
This manual gives you a complete overview of the FM 352 function module. It helps you
during installation and commissioning. The procedures involved in installation, wiring,
parameter assignment, and programming are described.
This manual is intended for the programmers of STEP 7 programs and for those responsible
for configuring, commissioning, and servicing automation systems.
Basic knowledge required
This manual presumes general knowledge in the field of automation engineering.
In addition, you should know how to use computers or devices with similar functions (e.g.,
programming devices) under the Microsoft® Windows® operating systems and have a
knowledge of STEP 7 programming.
Scope of the manual
This manual contains the description of the FM 352 electronic cam controller as valid at the
time it was published. We reserve the right to publish modifications of FM 352 functionality in
