Commissioning and configuration
EP9300-0022 28 Version: 2.3
Behavior when starting the EP9300-0022
All EtherCAT devices must be present when starting or resetting the EP9300-0022. This means that
all connected EtherCAT devices must be supplied with voltage at the same time before the start so
that the EP9300-0022 also starts up properly on the Profinet. A solution can be constructed more
flexibly with the CX8093.
Configuration of the EtherCAT devices
There are 4 types of EtherCAT devices:
• EtherCAT devices without process data
• EtherCAT devices with "simple" process data without parameterization
(as a rule, simple EtherCAT devices with digital inputs or outputs)
• EtherCAT devices with "simple" process data with parameters
(as a rule, EtherCAT devices with analog inputs or outputs)
• EtherCAT devices with different process data and parameters
(for example incremental encoders)
The rule for all of them is: they must be entered in the configuration.
Grouping digital inputs and outputs (pack terminals)
The digital input and output terminals can also be grouped according to their process data. This option can
be used with 2 or 4-channel terminals. To do this a 2 or 4-channel pack terminal (without asterisk) must be
appended to the GSDML file. In order to fill the byte, a 2 or 4-channel pack terminal (with asterisk) must be
appended next. The terminals must be physically and systematically plugged in one behind the other or
logically. The byte limit must not be exceeded.
Example
2-channel pack (without asterisk), after that 3 modules from 2-channel pack terminals (with asterisk) may be
appended.
Not permitted:
2-channel pack (without asterisk), then 2 modules from 4-channel pack terminals (with asterisk). This
exceeds the byte limit.
EtherCAT devices with different mapping options
Some EtherCAT devices offer the option to represent different process data. These are represented
differently on the basis of the parameters. In the Profinet controller such an EtherCAT device is represented
by submodules. The standard mapping is always integrated. If you want to use a different mapping that
deviates from the standard, then delete the standard submodule and insert the one that you wish to use. It
may be the case that, contradictory to the documentation for the EtherCAT device, not all mappings can be
used under EP9300-0022.
