EP9300-0022 38 Version: 2.3
5.7 Multi-configuration mode
Description
Multi-configuration mode enables users to operate different hardware, e.g. EP9300-0022 with varying
EtherCAT devices, with the same project configuration.
This description uses EtherCAT Terminals (ELxxxx) in the examples. The same principle applies to
EtherCAT Box modules (EPxxxx).
Task
The machine manufacturer has a machine, which is to be sold with different options. The options are usually
additional signals to be processed and logged, for which additional terminals are required.
For all these options the project configuration should be retained and only be varied via the software. The
actual machine options are included in the parameterization.
Solution
The multi-configuration mode is used to configure the maximum number of options in the project
configuration. If the machine has less than the maximum number of options, EtherCAT Terminals can be
omitted, since these signals are not required. Although unused EtherCAT Terminals are included in the
maximum project configuration, they can be disabled by the controller, so that the hardware and the
parameterized configuration match again. As soon as this is done, EP9300-0022 switches to normal data
exchange.
Advantage
Less effort for creating and maintaining projects, since the same project configuration can be used for
different hardware.
Example
The standard machine configuration, without options, consists of:
• 1x EP9300-0022
• 2x EP2008-0001
• 2x EP1008-0001
• 1x EP5101-0002
The following options can be added:
• With automatic adjustable axis: additionally one EP7041-0002
• With temperature measurement: additionally one EP3314-0002
The maximum extension (with optional EtherCAT devices represented in italics) thus looks like this:
• 1x EP9300-0022
• 2x EP2008-0001
• 2x EP1008-0001
• 1x EP5101-0002
• 1 x EP7041-0002
• 1 x EP3314-0002
It is this maximum configuration that is reflected in the hardware configuration.
If the machine is ordered without options, the EtherCAT devices EP7041-0002 and EP3314-0002 must be
deactivated in the project planning. To this end the EP9300-0022 is informed of which EtherCAT devices are
omitted by Record Data (acyclic communication). The EtherCAT devices are identified via their position.
