PCIE-1203 User Manual 2

1.1 EtherCAT Introduction

EtherCAT (Ethernet Control Automation Technology) is a high-performance, Ether-

net-based fieldbus industrial network system. The protocol is standardized in IEC

61158 and applies to automation applications that need faster and more efficient

communications. Short data update times with precise synchronization make Ether-

CAT suitable for real-time requirements in automation technology.

1.1.1 EtherCAT

1.1.1.1 Functional Principle

EtherCAT is a real time, high speed and flexible Ethernet based protocol. In Ether-

CAT network, the master sends Ethernet frames through all of the slave nodes. Stan-

dard Ethernet packets or frames are no longer received, interpreted, and copied as

process data at every node. Instead, slave devices read the data addressed to them

and the input data are inserted at the same time while the telegram passes through

the device, processing data “on the fly”. Typically the entire network can be

addressed with just one frame.In comparison to other Ethernet based communication

solutions EtherCAT utilizes the available full duplex bandwidth efficiently.

Figure 1.1 EtherCAT Function Principle

1.1.1.2 Protocol

Data exchange are cyclically updated between EtherCAT master and slaves. Data in

EtherCAT frames are transported directly within the standard IEEE 802.3 Ethernet

frame using Ethertype 0x88a4 and are processed by the EtherCAT Slave Controller

on the fly. Each EtherCAT datagram is a command that consists of a header, data

and a working counter. The datagram header indicates what type of access the mas-

ter device would like to execute:

Read, write, read-write

Access to a specified slave device through direct addressing

Access to multiple slave devices through logical addressing

Logical addressing is used for the cyclical exchange of process data. The header and

data are used to specify the operation that the slave must perform, and the working

counter is updated by the slave to let the master to know that a slave has processed

the command.

Every EtherCAT datagram ends with a 16 Bit Working Counter (WKC). The Working

Counter counts the number of devices that were successfully addressed by this Eth-

erCAT datagram.

3 PCIE-1203 User Manual

Chapter 1 Introduction

Figure 1.2 EtherCAT Protocol

EtherCAT datagrams are processed before receiving the complete frame.

In case data is invalid, the frame check sum (FCS) is not valid and the slave will not

set data valid for the local application.

1.1.1.3 Topology

EtherCAT supports a variety of network topologies, including line, tree, ring and star.

The line and tree topologies are more conducive to fieldbus applications because

they require fewer connections and utilize a much simpler and more flexible cabling

schema that switches and hubs are not necessary for lines or trees topology.

Figure 1.3 EtherCAT Topology

Inexpensive industrial Ethernet cables up to 100m apart, can be used between two

nodes in 100BASE-TX mode. EtherCAT makes a pure bus or line topology with hun-

dreds of nodes possible without limitations. Up to 65,535 devices can be connected

to EtherCAT, so network expansion is almost unlimited.

EtherCAT supports individual nodes to be connected and disconnected during opera-

tion. If one of the slaves in the network is removed, the rest of the network can con-

tinue to operate normally. Additionally, EtherCAT also enables other communication

features such as cable redundancy or even master redundancy with Hot Standby.

PCIE-1203 User Manual 4

1.1.1.4 Synchronization

A Distributed Clock (DC) mechanism is used to provide highly precise time synchro-

nization between slaves in an EtherCAT network, which is equivalent to the IEEE

1588 Precision Time Protocol standard. By using distributed clocks, EtherCAT is able

to synchronize the time in all local bus devices within a very narrow tolerance range.

All EtherCAT slaves are provided with an internal clock which named as System

Time (tLocal Time). One EtherCAT Slave, usually the first slave, will be used as a Ref-

erence Clock and cyclically distributes its Clock.

Possible misalignments between the reference clock and the clocks of the other

slaves are usually due to the following reason: when a slave is switched on, the inter-

nal free-running register that holds the current time is reset to zero. Unfortunately,

this action does not take place exactly at the same time in all the different slaves, and

this result in an initial offset (toffset) among clocks that has to be compensated.

Figure 1.4 EtherCAT Distributed Clock

Typically, the master sends a broadcast to all other slaves in the system. Once

receiving the message, slaves will latch the value of their internal clock. There are

two latch values, one is receiving and the other is returning back. Thus, the master

can read all latched values and calculate the delay for each slave (tPropagation Delay).

Delays will be stored into offset register. In the following, master will send a message

periodically to all other slaves in EtherCAT network to make the first slave the refer-

ence clock and forcing all other slaves to set their internal clock by the calculated off-

set.

∆t = (tLocal Time + tOffset - tPropagation Delay) - tReceived System Time
