Chapter 1 Detail Drive Configuration and Operation
The bits for each parameter are broken down as follows:
• Bit 0 - “Digital Input”
• Bit 1 - “Adapter 1”
• Bit2 - “Adapter 2”
• Bit 3 - “Adapter 3”
• Bit 4 - Not Used
• Bit 5 - “Adapter 5”
• Bit 6 - Not Used
• Bit 7 - “DriveLogix”
Ownership falls into two categories:
• Exclusive: Only one adapter at a time can issue the command and only
one bit in the parameter will be high.
• Non Exclusive: Multiple adapters can simultaneously issue the same
command and multiple bits may be high.
Some ownership must be exclusive; that is, only one Adapter at a time can issue
certain commands and claim ownership of that function. For example, it is not
allowable to have one Adapter command the drive to run in the forward
direction while another Adapter is issuing a command to make the drive run in
reverse. Direction Control, therefore, is exclusive ownership.
Conversely, any number of adapters can simultaneously issue Stop Commands.
Therefore, Stop Ownership is not exclusive.
Example: The operator presses the Stop button on the Local HIM to stop the
drive. When the operator attempts to restart the drive by pressing the HIM Start
button, the drive does not restart. The operator needs to determine why the drive
will not restart.
The operator first views the Start owner to be certain that the Start button on the
HIM is issuing a command.
When the local Start button is pressed, the display indicates that the command is
coming from the HIM.
