Switching on the power supply
Please note
Please observe the switching−on instructions in the manual
of your control system (PLC/IPC).
If the control system and the field bus slaves have separate
power supplies, the devices must be switched on in the
following sequence:
1. Switch on the operating voltage supply of all bus
subscribers (I/O Devices).
2. Switch on the operating voltage supply for the controller.
Addressing, configuration and parameterisation
The address space of a CPX terminal in the EtherCAT network
is limited. Before starting up or configuring the CPX terminal,
determine the number of assigned inputs and outputs.
Configuration of a CPX terminal and the related CPX bus node
depends on the control system used. The basic procedure
and the required configuration data are presented in the
following pages.
A CPX terminal in the EtherCAT network can be parameterised
only with a handheld control unit (CPX−MMI) or the Festo
Maintenance Tool (CPX−FMT) (no parameterization through
the control system).
