SFA-5000 • SFA-10000 EtherCAT
•
Auto Increment Addressing = Position Addressing: 16 bits indicate the
physical position of the Slave inside the network while 16 bits are
scheduled for local memory addressing; when the Slave receives the
frame then it increments the position address and the Slave receiving
address 0 is the addressed device;
•
Fixed Addressing = 16 bits indicate the physical address of the Slave
inside the network while 16 bits are scheduled for addressing the local
memory;
•
Logical Address = the Slave is not provided with its own individual
address, but it can read and write data in a section of the total memory
space available (4 Gigabytes).
For complete information refer to the “6.1.5 Addressing” section on page 52.
4.4 Line Termination
EtherCAT network needs no line termination because the line is terminated
automatically; in fact every Slave is able to detect the presence of the
downstream Slaves. For complete information refer to the “6.1.4 Line
Termination” section on page 51.
4.5 Ground connection
To minimize noise connect properly the shield and/or the connector housing
and/or the frame to ground. Connect properly the cable shield to ground on
user's side. Lika's EC- pre-assembled cables are fitted with shield connection to
the connector ring nut in order to allow grounding through the body of the
device. Lika's E- connectors have a plastic gland, thus grounding is not possible.
If metal connectors are used, connect the cable shield properly as recommended
by the manufacturer. Anyway make sure that ground is not affected by noise. It
is recommended to provide the ground connection as close as possible to the
device. We suggest using the ground point provided in the cap (see Figure 1, use
1 TCEI M3 x 6 cylindrical head screw with 2 tooth lock washers).
