default baud rate.
5.2.6 Setting up the DeviceNet Baud rate
If you wish to change the baud rate to a fixed speed, you can set it in two different places.
The first is the standard location for the DeviceNet baud rate, which is in the DeviceNet
object. This is where most configuration tools will look to change the baud rate. This is fine on
normal DeviceNet systems, however the JDC provides some extended DeviceNet
functionality above normal systems to allow the autobaud functionality. This extension is not
defined by ODVA thus cannot be attached to any of the standard DeviceNet objects to ensure
compatibility. You can still use the baud rate in the normal manner; it will just not allow the
autobaud setting.
We have provided an extended baud rate parameter at attribute 7 of the parameter object to
allow for the autobaud baud rate setting. (See Table 5-1).
These values can be set and retrieved by using the standard set and get services on class 15
(F
hex
), instance 7, attribute 1. (See Table 5-1).
