SMC–4000 User Manual
Method #1
The first method is to use the BOOT-P utility via the Ethernet connection (the SMC–4000 must be
connected to the network and powered). For an explanation of BOOT-P see Third Party Software.
Method #2
The second method for setting an IP address is to send the IA command through the SMC–4000 main
RS-232 port. The IP address you want to assign may be entered as a 4 byte number delimited by commas
(industry standard uses periods) or a signed 32 bit number. (Ex. IA 124,51,29,31 or IA 2083724575) Type
in BN to save the IP address to the controller's non-volatile memory.
*Note Yaskawa recommends that the IP address selected is not one that can be accessed across the
Gateway. The Gateway is an application that controls communication between an internal
network and the outside world.
The third level of Ethernet addressing is the UDP or TCP port number. The Yaskawa controller does not
require a specific port number. The port number is established by the master each time it connects to the
controller.
Ethernet Handles
An Ethernet handle is a communication resource within a device. The SMC–4000 can have a maximum of
8 Ethernet handles open at any time. Pings and ARPS do not occupy handles. If all 8 handles are in use
and a 9th master tries to connect, it will be sent a “reset packet” that generates the appropriate error in its
native application.
Each SMC–4000 controls up to four axes of motion, referred to as A-D or XYZ. The host computer can
communicate directly with any SMC–4000 via an Ethernet or RS-232 connection.
CAUTION: Be sure there is only one BOOT-P server running. If your network has DHCP or
BOOT-P running, it may automatically assign an IP address to the controller upon linking it to
the network. To ensure that the IP address is correct, please contact your system
administrator before connecting the controller to the Ethernet network.
