Commissioning and configuration
EP9300-0022 27 Version: 2.3
5.3 Profinet configuration
GSDML file
Only EtherCAT Box modules existing in the GSDML file are supported; extensions are possible
however. The GSDML supports submodules; ascertain whether your PROFINET master/controller
supports these submodules. If this is not the case, some terminals cannot be used!
Alternatively the CX8093 can be used; this generally supports all EtherCAT slaves.
General
The EP9300-0022 is always implemented in the Profinet controller (Master) with the help of a GSDML file.
The GSDML file contains all the parameterization data required for the operation of the EP9300-0022 on the
Profinet controller. The configuration tool reads this file and then provides the data to the user.
The EtherCAT devices that can be operated on the EP9300-0022 are also specified in the GSDML file. Not
all EtherCAT devices are supported. Therefore, inform yourself first whether the EtherCAT devices that you
wish to use are also supported by the EP9300-0022.
Data in the DAP (Device Access Point)
2 x 2 bytes of data are located in the DAP of the GSDML file:
• ECCycleCounter (2 bytes). This is incremented with each EtherCAT cycle (1 ms), provided the
EtherCAT Master is in the "OP" state.
• Status (2 bytes). This indicates individual status information bit by bit. These are occupied as follows:
◦ Bit 0 - IsSynchron – is set when the EP9300-0022 is operated as a PTP Slave or an IRT device
and is synchronous.
◦ Bit 1 - IsPTPMaster – is set when the EP9300-0022 is operated as a PTP Master.
◦ Bit 2 - ECFrameError – is set when a problem is determined at the EtherCAT output. The Profinet
diagnostics or the alarms must be read in order to obtain further information.
Parameters in the DAP
Activate PN Fallback Value
Off -> EtherCAT data are written to zero.
On -> there is a possibility to use another default value with outputs. With digital outputs, for example, the
current output process value can be frozen or set to 0 or 1 in case of a Profinet communication error.
Data Presentation
Intel Format -> data are represented in Intel format.
Motorola Format -> data are represented in Motorola format. In Word variables, for example, the high and
low bytes are exchanged.
EBus error behaviour
Set IOs to 0 -> input and output data are set to zero in case of an EtherCAT error.
Legacy -> input data retain their last state, but are no longer updated; output data can still be set (depending
on the position of the terminal).
Mapping
The EP9300-0022 is typically used in a group with EtherCAT devices that are connected to the EtherCAT
output. The EtherCAT devices are a component of the GSDML; the EtherCAT devices are parameterized
from the Profinet controller.
You must enter the EtherCAT devices in the hardware configurator exactly as they are physically connected.
If EtherCAT star hubs and/or EtherCAT junctions are used, it is important to know the order in which the
other EtherCAT devices were entered in the process image (see
EtherCAT configuration [

30] ).
