The setting you make to select a protocol is described detailed in the
protocol-specific sections.
In delivery state no protocol settings are stored in the module. In this case
only the desired protocol has to be chosen. To take over a changed rotary
switch setting (protocol setting), a power cycle or “Reset” from the web
interface is necessary.
Please wait 10 seconds before power cycling the device after start-up with
changed rotary switch settings due to internal memory write processes.
Once you have set the protocol using the rotary encoding switches, the
module stores this setting when it starts in cyclic communication. Changing
the protocol using the rotary encoding switch is no longer possible after this
point. The module will always start using the stored protocol from that point
on. The IP address can be changed depending on the selected protocol.
To change the protocol, carry out a factory reset. In this way you restore the
factory settings of the respective module. How you perform the factory reset
for your module is described in chapter
If you position the rotary encoding switch in a manner that is invalid, the
device signals this to you with a blink code (the BF/MS/ERR LED blinks in
red three times).
4.1.1
EtherNet/IP
If you decide to use EtherNet/IP as a protocol, use the first rotary encoding
switch to set the 100 value of the last octet of the IP address of the module.
Using the first switch, a value from 0 to 2 can be set for the IP address. The
second rotary encoding switch (x10) can be used to configure the 10 position
of the last octet of the IP address, and the third rotary encoding switch (x1)
allows you to configure the 1 position. Values between0 and 9 can be
selected for the second and third switches. The first three octets of the IP
address are set by default to 192.168.1.
For example, the rotary encoding switch setting 2(x100), 1(x10) and 0(x1)
gives you an IP address of 192.168.1.210 for EtherNet/IP.
For more information use the LioN-P EtherNet/IP Digital I/O manual.
