3. Click Slot options.
The Sensor Digital I/O dialog box has the following areas:
• Invert Inputs check boxes
To invert inputs, select the check boxes of the inputs you want inverted. When digital inputs are
displayed with the I/O Bit Monitor they are displayed after they have been inverted.
• Invert Outputs check boxes
To invert outputs, select the check boxes next to the outputs you want inverted. When digital
outputs are displayed with the I/O Bit Monitor they are displayed before they have been inverted.
• Counter Type Selection
The Sensor Digital I/O is equipped with quadrature and edge counters. Only one of these two
counters may be used at a time. Similarly, only one of the counters on the Sensor or
Communication Digital I/O modules can be enabled at a time. Refer to Using Counters for details.
This section will be unavailable if the Communication DI/O is configured in Parallel Event mode
because this mode uses all inputs on both the Communication DI/O and Sensor DI/O.
This dialog box has two available commands:
• Update RMC
This command sends the Sensor Digital I/O options to the RMC, issues an Update Flash
command, and resets the RMC to make all changes take effect.
• Cancel
This command closes the dialog box and discards changes.
5.1.6 Communication Digital I/O
5.1.6.1 Using the Communication Digital I/O
The Digital I/O module provides a simple communications interface between the motion controller
and the system controller or Programmable Controller (P/C). RMC modules are available with two
types of Digital I/O. When a digital I/O is installed to the left of the CPU, it is called the
Communication Digital I/O. When a digital I/O is installed to the right of the CPU, it is called the
Sensor Digital I/O. Both share the same specifications, refer to Digital I/O Specifications for this
information. However, the Sensor and Communication Digital I/O’s have different features. This
topic discusses the features of the Communication Digital I/O.
The Communication Digital I/O has eighteen digital inputs and eight digital outputs. The use of
these digital inputs is configured using the Communication DI/O Options dialog box. To open
this dialog box:
1. On the Tools menu, click Module Configuration.
2. In the Slots list, click the Comm Digital I/O item. This item will only be available if a
Communication Digital I/O module is installed.
