Electrical Connections; Bus Coupler - Emerson AVENTICS EtherCAT Descripción De Sistema

3 General Instructions on Equipment and Product
Damage
Disconnecting connections while under voltage will destroy the electronic
components of the valve system!
Large differences in potential occur when disconnecting connections under
voltage, which can destroy the valve system.
Make sure the relevant system component is not under voltage before as-
u
sembling the valve system or when connecting and disconnecting it electri-
cally.
An address change will not be effective during operation!
The bus coupler will continue to work with the previous address.
1. Never change the address during operation.
2. Disconnect the bus coupler from the power supply UL before changing the
positions of switches S1 and S2.
Malfunctions in the fieldbus communication due to incorrect or insufficient
grounding!
Connected components receive incorrect or no signals.
1. Make sure that the ground connections of all valve system components are
electrically connected to each other and grounded.
2. Verify proper contact between the valve system and ground.
Malfunctions in the fieldbus communication due improperly laid communica-
tion lines!
Connected components receive incorrect or no signals.
Lay the communication lines within buildings. If you lay the communication
u
lines outside of buildings, the lines laid outside must not exceed 42 m.
The valve system contains electronic components that are sensitive to electro-
static discharge (ESD)!
If the electrical components are touched by persons or objects, this may lead
to an electrostatic discharge that could damage or destroy the components of
the valve system.
1. Ground the components to prevent electrostatic charging of the valve sys-
tem.
2. Use wrist and shoe grounding straps, if necessary, when working on the
valve system.
4 About This Product

4.1 Bus coupler

The AES series bus coupler for EtherCAT establishes communication between the
superior controller and connected valves and I/O modules. It is designed for use
as a slave only on
an EtherCAT bus system in accordance with IEC 61158 and IEC 61784-1, CPF 12
(EtherCAT). Therefore, the bus coupler must be configured. The
CD R412018133, included on delivery, contains an XML file for the configuration
(see "Loading device description data").
During cyclical data transfer, the bus coupler can send 512 bits of input data to
the controller and receive 512 bits of output data from the controller. To com-
municate with the valves, an electronic interface for the valve driver connection is
located on the right side of the bus coupler. The left side of the device contains
an electronic interface which establishes communication with the I/O modules.
The two interfaces function independently.
The bus coupler can actuate a maximum of 64 single or double solenoid valves
(128 solenoid coils) and up to 10 I/O modules. It supports EtherCAT data commu-
nication.
