Commissioning
6 Commissioning
6.1 Preliminary considerations
Caution!
Uncontrollable triggered processes
The plant where the device is installed may be damaged.
Before commissioning, make sure that all processes run in a controlled manner.
These instructions contain all important information required to operate the
IDENTControl Compact unit with the PROFIBUS DP. Due to the wide variety of
field bus programming options with the PROFIBUS, we are unable to make
specific statements about commissioning.
One important aspect of the operation of an extended identification system on the
PROFIBUS DP is the time response of the overall system. The answer to the
question "How long after the positioning of a data carrier in front of a read/write
station will the read data be available in the computer or PLC?" depends on many
different factors.
The most important factors that determine the time response are:

If you are planning larger projects or gaining basic experience in programming a
PROFIBUS DP system, we recommend constructing a laboratory set up of your
application before installing the system in the plant. Use this laboratory set up to
test the process of data transfer to the PROFIBUS DP master or the host system.
Note!
There are configuration tools available to help PROFIBUS DP users plan a
network and put it in operation even if they do not have extensive experience with
the underlying communication sequences.
The system software of PLCs with the PROFIBUS DP communication interface
often offers suitable options for configuring and managing a bus.
