Settings 1 through E can be changed using the Bimba IQ
®
Stepper software (use Bimba IQ
®
Servo for servo drives). Setting 0 is
always “10.10.10.10”, the universal recovery address. If someone were to change the other settings and not write it down or tell
anyone, then you will not be able to communicate with your drive. The only way to “recover” it is to use the universal recovery
address.
Setting F is “DHCP”, which commands the drive to get an IP address from a DHCP server on the network. The IP address auto-
matically assigned by the DHCP server may be “dynamic” or “static” depending on how the administrator has configured DHCP.
The DHCP setting is reserved for advanced users.
Your PC, or any other device that you use to communicate with the drive, will also have a unique address.
On the drive, switch settings 1 through E use the standard class B subnet mask (i.e. “255.255.0.0”). The mask for the universal
recovery address is the standard class A (i.e. “255.0.0.0”).
One of the great features of Ethernet is the ability for many applications to share the network at the same time. Ports are used to
direct traffic to the right application once it gets to the right IP address. The UDP eSCL port in our drives is 7775. To send and
receive commands using TCP, use port number 7776. You’ll need to know this when you begin to write your own application.
You will also need to choose an open (unused) port number for your application. Our drive doesn’t care what that is; when the first
command is sent to the drive, the drive will make note of the IP address and port number from which it originated and direct any
responses there. The drive will also refuse any traffic from other IP addresses that is headed for the eSCL port. The first applica-
tion to talk to a drive “owns” the drive. This lock is only reset when the drive powers down.
If you need help choosing a port number for your application, you can find a list of commonly used port numbers at www.iana.org/
assignments/port-numbers.
One final note: Ethernet communication can use one or both of two “transport protocols”: UDP and TCP. eSCL commands can
be sent and received using either protocol. UDP is simpler and more efficient than TCP, but TCP is more reliable on large or very
busy networks where UDP packets might occasionally be dropped.
