Configuration

To use the multi-configuration mode, set the "MultiConfigurationMode" parameter to "active" in the DAP (Device Access Point) under "ER9320 Settings".

There are two ways to activate or deactivate EtherCAT devices:

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 multi-configuration mode 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.

	No subslots Subslots are not counted and cannot be used for the multi-configuration mode. Only slots can be used, irrespective of a module using subslots or not.

	No Shared Device The Shared Device feature cannot be used when the multi-configuration mode is used.

	No pack or () terminals Pack or () terminals cannot be used in multi-configuration mode.
