Getting started
This chapter is intended to provide a generic guide for setting up SI-PROFINET RT on a
PROFINET network. The setup flowchart (
SI-PROFINET RT setup flowchart
page 17) is intended as a guide only, and is provided to detail the stages that are
required to achieve a functioning network. It is recommended that this entire chapter is
read before attempting to configure a system.
5.1
SI-PROFINET RT XML file (or GSDML file)
A GSDML (General Station Description Markup Language) file is required to describe
the drive interface to a PROFINET controller or PLC. This is an XML file, the structure of
which is specified by the PROFIBUS INTERNATIONAL organization
(www.profibus.org).
The GSDML file is used in conjunction with the network configuration software to
configure the SI-PROFINET RT module for cyclic data exchange. All relevant drive
parameters are available as a 'module' to be added to the cyclic data 'slots'.
A non-specific 'module' is also provided so that the user can allocate a parameter within
the drive (or option module), that is not directly available as a specific 'module'. Some
'modules' require the slot position to be specified and the menu and parameter to be
specified. These options will be available from a drop-down selection list within the
'Parameters' tab of the 'module' properties.
The GSDML file for SI-PROFINET RT can be downloaded from the Control Techniques
support website (www.ctsupport.com), providing you are registered or from the main
Control Techniques company website (www.controltechniques.com), providing you are
registered or, alternatively, requested from your local Control Techniques Drive Centre
or supplier.
For further information regarding the use of the GSDML file please refer to the PLC
documentation.
5.2
Configuring the PROFINET IO communications
SI-PROFINET RT does not require the module parameters to be configured by the user
in order to achieve PROFINET cyclic communications. All the necessary configuration
is undertaken by the network controller or PLC during the start-up sequence, and after
the network configuration is programmed into the network controller or PLC.
It must be noted that when configuring the cyclic data modules, if a module is configured
but the associated drive parameter does not actually exist in the drive, then the PLC will
not start up correctly and will indicate a configuration fault.
If a cyclic module which requires the drive slot position is used, but the drive slot
position is not specified, then no fault indication will be indicated on the PLC and no data
will be returned by the module.
