Commissioning and configuration
EP9300-0022 39 Version: 2.3
Without options, there are two EP2008-0001 (at positions 1 and 2), two EP1008-0001 (at positions 3 and 4)
and one EP5101-0002 (at position 5). The EtherCAT devices at positions 6 and 7 (optional EtherCAT
devices) must be deactivated.
If the machine is ordered with the option "automatic adjustable axis", only the EtherCAT device at position 7
needs to be deactivated.
Position of optional EtherCAT devices
Optional EtherCAT devices can also be present at any position in the EtherCAT network, in order to
possibly deactivate them. As shown in the example, they do not have to be inserted at the end.
First steps
In order to enable EP9300-0022 to operate in multi-configuration mode, MultiConfigurationMode must be set
to "TRUE" in the DAP (device access point).
There are two possible setting options.
Option 1
This is perhaps a version for testing, since the hardware configuration must be adjusted, which should
preferably be avoided.
In the DAP there is a MultiConfigurationMode setting with the slots. Here you can disable EtherCAT
Terminals, which are configured but not present.
For some PROFINET controllers this must happen on startup, while other PROFINET controllers enable it to
occur at runtime, which simplifies testing significantly. Disabling/enabling of terminals at runtime is a feature
of the PROFINET controller and may or may not be possible in practice, depending on the manufacturer of
the PROFINET controller.
Option 2
The configuration is sent by the PLC via the record data. Here too, the manufacturers offer different options.
Contact the manufacturer of your PROFINET controller, if you have any queries.
A requirement for option 2 is that your PROFINET controller allows and supports access to the record data.
PROFINET record
data (write request) Value Meaning
Slot* 0 Slot number, always "0"
SubSlot* 1 Sub-slot number, always "1"
Index 0#2010 PROFINET index number
Length variable Length of the following data
Data Each Bus Terminal requires 2 bits:
00
bin
terminal present
10
bin
terminal not present
Enabling/disabling of the EtherCAT devices
* For some PROFINET controllers these data are automatically taken from the GSDML and do not have to
be configured.
Procedure
Once the station has been configured, the following steps are required.
If the machine is ordered with the maximum configuration (with all options), generally no action is required,
since the hardware matches the project configuration.
If one of the options is not included, then hardware and project planning differ. The PROFINET coupler
indicates this via the message "Module difference".
Now disable the terminals, which are not present. When this is done, the message "Module Difference" is
removed from the coupler. If the message "Module Difference" remains, you may have the wrong slot or too
few slots disabled.
