3-2 Use Auto Start Mode
Why Use Auto Start Mode? Auto Start Mode offers you a quick and easy method of getting your
ArmorPoint I/O system ‘up and running’. If your ArmorPoint I/O
application can use default configuration, you should use Auto Start
Mode to easily begin operations.
Once your adapter is:
• installed
• connected to the system’s I/O modules
• online (in RSNetWorx for DeviceNet)
you only need to choose the Auto Start Mode option in the adapter’s
Parameters window in the RSNetWorx for DeviceNet software and the
adapter begins working with a default configuration.
What Does Auto Start Mode Do?
When using Auto Start Mode, the adapter:
1. Sets all modules on the backplane to Auto Baud
2. Reads the Subnet module’s identity information
3. Sets backplane modules’ addresses sequentially
4. Generates a scanlist for the Subnet
5. Maps I/O data, based on byte, word, double-word, or fixed
boundaries
When this sequence of events is completed, the ArmorPoint I/O
modules connected to the adapter are ready to accept connections
from a scanner.
IMPORTANT
Although Auto Start Mode allows your adapter to
operate with a default configuration, you can write a
custom configuration after operation has begun.
For more information on how to write custom
configuration for your adapter on DeviceNet, see
Chapter 5, Add the ArmorPoint DeviceNet Adapter to
the DeviceNet Scanner’s Scanlist.
