Configuration
EK9300 35 Version: 3.2.6
The mapping is card-slot-oriented, i.e. you must enter the terminals in the hardware configurator in exactly
the same way as they are physically connected. It becomes a little more complicated if EtherCAT distributor
boxes are used. In this case it is important to know the order in which the other EtherCAT terminals were
entered into the process image (
see EtherCAT Mapping [
}
36] ).
Behavior when starting the Bus Coupler
All EtherCAT devices must always be present when starting the Bus Coupler (or resetting), i.e. all
EtherCAT slaves must be supplied with power before or at the same time so that the coupler on the
PROFINET also starts up properly.
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 but without parameterization (usually simple digital
terminals)
• EtherCAT devices with “simple” process data and with parameters (usually analog signals)
• EtherCAT devices with different process data and parameters (for example incremental encoders)
All of these 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.
Sample:
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 terminals with different mapping options
Some EtherCAT terminals offer the option to represent different process data. These are represented
differently on the basis of the parameters. In the PROFINET controller such a terminal 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 terminal or EtherCAT box, not all
mappings can be used under the PROFINET coupler.
