5.4.1
Ethernet Dynamic and Static IP Address Setup
Use IPMODE command to setup either Dynamic or Static IP mode
The IP mode command (IPMODE) is used to set the controller's IP mode. In order for
this setting to take effect, please save this setting in the controller's non-volatile memory
and reset the controller.
As the name implies, Static IP addresses are the same every time you connect. Dynamic IP
addresses may change each time you connect to the Ethernet Local Area Network. .
Dynamic IP addresses are the normal customer access method used by most ISPs or
Service Providers and this is the default IP mode for this product.
When your 8743-CL controller is configured for Dynamic IP addressing, upon power up
or connection to the LAN it will automatically send a message to every device on the
network and ask if the other device(s) are DHCP servers. (There should be exactly one
DHCP server on the network.) The non-DHCP server devices will ignore the message; the
only DHCP server on the network will respond to the 8743-CL with a "use IP address
xx.xx.xx.xx" message. The 8743-CL will then begin using this IP address.
When your 8743-CL controller is configured for Static IP addressing, upon power up it
will retrieve its previously-stored IP address from non-volatile memory within the 8743-
CL and begin using this IP address.
Having a static IP address for your dedicated server means an IP address will be assigned
to your server (controller) only once and that IP address will belong to your dedicated
server forever. A static IP address will be given out to your dedicated server so that every
time it logs in it will be using the same IP address for all of its sessions.
NOTE: Send Ethernet commands via USB interface as Ethernet
communication may become unstable during Ethernet settings configuration.
While connected via USB, use the Picomotor application software to send
commands (Go to 'Terminal' tab).
