Introduction
2.1
What is PROFINET?
PROFINET is an Ethernet based industrial network protocol adapting Ethernet
hardware and protocols to the real time needs of industrial automation. It is similar to
PROFIBUS in that it enables distributed IO control from a PLC.
2.2
Introduction to SI-PROFINET RT
SI-PROFINET RT is an option module that allows any suitable Control Techniques
variable speed drive to be connected to a PROFINET network as a PROFINET IO slave
device.
It is possible to use more than one SI-PROFINET RT or a combination of SI-PROFINET
RT and other option modules, to add additional functionality such as extended I/O,
gateway functionality, or additional PLC features.
2.3
Option module identification
The SI-PROFINET RT module can be identified by:
1. The label located on the option module.
2. The color coding across the front of the SI-PROFINET RT module (yellow/green).

2.3.1 Date code format
The date code is split into two sections: a letter followed by a number.
The letter indicates the year, and the number indicates the week number (within the
year) in which the option module was built. The letters start with A for 1991 (B for 1992,
C for 1993 etc.).
Example: A date code of W31 would correspond to week 31 of year 2013.
