What Is the ArmorPoint DeviceNet Adapter? 2-11
The baudrate may not take effect until power is recycled or the I/O
modules are reset.
Backplane/Subnet Baudrate performs the following functions:
Sets the adapter’s Subnet baudrate
Sends a message to all connected backplane I/O modules. If an
I/O module is set to autobaud, it receives the message but
ignores the new baudrate.
IMPORTANT
Changes to the Backplane/Subnet Baudrate
parameter only take effect if they are downloaded on
an individual basis. (For example, if you change the
Backplane/Subnet Baudrate and download the
changes with additional changes to other features,
the Backplane/Subnet Baudrate remains at the
previous setting.)
Also, this parameter should be set to ‘Do Nothing’
when you download all parameters or when
Automatic Device Replacement is enabled for
the adapter.
If you want to set an I/O module to use a specific
baudrate (i.e., 125, 250, 500), you must first disable
Backplane Autobaud for that module.
