EtherCAT Communication setting
The setting and startup of EtherCAT communication are described below.
For details, refer to "LECSN-T Instruction Manual, Section 18.1
”.
(1) Connection with the upper side
Set up the upper side following the manual of the upper side used. For the setup, the EtherCAT Slave
Information (ESI) file listing the information about the communication setting of devices is available.
Store the ESI file in the upper side to use it. The upper side configures the setting for the slave
connected to the master according to the contents of the ESI file corresponding to the slave
connected.
Please install the ESI file from the following link (SMC website).
https://www.smcworld.com/assets/manual/other/files/LECSNx-Tx-E_ESI.zip
POINT
Use the latest ESI file when setting up the upper side. If the ESI file is old, newly
added objects may not be usable.
(2) Node address setting
Set the node address of EtherCAT with the axis selection rotary switch (SW2/SW3) on the display,
[Pr. PN01 Node address setting] or SII Configured Station Alias as necessary. You can set a node
address as follows. After the node address setting is changed, cycle the power.
Axis selection rotary
switch (SW2/SW3)
Pr. PN01
SII Configured Station
Alias
Node address setting value
00h
0000h
0001h to FFFFh
The value set in SII Configured Station Alias via network
is the node address.
00h
0001h to FFFFh
0000h (Note)
The value of [Pr. PN01] is set as the node address.
01h to FFh
0000h to FFFFh
0000h (Note)
The set value of the rotary switch (SW2/SW3) is set as
the node address.
Note. If the value in SII Configured Station Alias is set to other than 0000h, the ERROR LED of the network card blinks.
Cycling the power resets the set value in SII Configured Station Alias to 0000h and this enables the driver to start normally.
POINT
The node address of drivers complies with the specifications of Explicit
Device Identification. Configure the setting of Set Explicit Device
Identification for the upper side.
Do not connect multiple devices with the same node address setting.
Node address setting via network and Configured Station Alias (0012h) are
available with the combination of drivers and network cards .
If the value in SII Configured Station Alias is set to other than 0000h when
the node address is set with the axis selection rotary switch (SW2/SW3) or
[Pr. PN01 Node address setting], the ERROR LED of the network card
blinks. Cycling the power resets the set value in SII Configured Station Alias
to 0000h and this enables the driver to start normally.
