4 Modules
4.1 Bus Coupler
The Ventura FIO bus coupler Converts the physical transfer technology
(twisted pair) to LVDS (E-bus) and gene rates the system Voltages required
by the LVDS modules. The standard 100 Base Tx lines used for office
communications network connect to the one side, de Ventura FIO I / O
modules for the process signals connect to the other. This is how the
Ethernet EtherCAT protocol is retained right through to the load I / O
modules. At the end of the modular device, the connection between the
forward and return lines is automatically closed, the effect being did another
100 Base Tx line can be plugged in to connect the next EtherCAT unit to the
second bus coupler port.
You will get the best results concerning disturbing emission, if you put the
shielding of the EtherCAT cable on the function earth.
Use for it e.g. Shield connection terminal block (see section 5.2)
