2.1 Configuration
General commissioning instructions
Configuration of the higher-order controller demands a very
accurate procedure, as different configuration specifications
are sometimes necessary for each participant, i.e. for each
device and each “box” in the EtherCAT netwo rk, due to the
modular structure.
2.1.1 Hot Connect functionality
Hot Connect functio nal i ty makes it possi ble to co nnect and
disconnect parts of the network during operation. This can be
done by disconnecti n g/connecti ng the communicatio n line,
switching the participant on/off , or by other means.
Hot Connect can acce ss this predefined address thanks to the
option of address reservation in the CTEU-EC bus node using
DIL switches ( section 1.4.5).
The first EtherCA T participant after the master should not be
a Hot Connect-configured participant, as this will slow down
link detection at the master.
2.1.2 Regist ering participant properties (“ESI file”) in the configuration
program
When you place a new EtherCAT parti cipant, i.e. an EtherCAT
device, into operation for the first time, you must inform the
configuration and programming software about certai n pro p-
erties of the participant.
The properties of the various participants are managed in a
configuration file - the EtherCA T slave information file (ESI
file).
