Digital Inputs
The digital inputs are reserved by the current mode you are using. Refer to Input to Event Mode,
Parallel Position Mode, Command Mode, or Parallel Event Mode for details.
Digital Outputs
The Communication Digital I/O has eight digital outputs. When using Input to Event Mode,
Parallel Position Mode, or Parallel Event Mode, these inputs can be used in the following three
ways. Refer to Command Mode for details on their use in that mode.
• In Position: As many outputs as installed axes are used to indicate when the In Position bit of the
Status word is set. These bits start at bit 0. Therefore, output 0 represents the In Position bit of
axis 0, output 1 represents the In Position bit of axis 1, etc.
• Auto Stop Error: If there are four or fewer axes in the motion controller, then one additional bit
per axis is reserved to indicate when an axis has stopped due to an error. This bit is set when an
error occurs—as marked in the Status word—which is also set in the Auto Stop word. These bits
start at bit 4. Therefore, output 4 represents the Auto Stop Error bit for axis 0, output 5 represents
the Auto Stop Error bit for axis 1, etc.
• User Controlled: Any bits still unused can be set and reset using the Set Outputs and Reset
Outputs commands. Attempts to use these commands on bits reserved for In Position or Auto
Stop will be ignored. In Input to Event and Parallel Event modes, bits that default to being used
for In Position and Auto Stop Errors may be overridden to become user controlled. To do this,
click Mode options from the Communication DI/O Options dialog box.
