• The outputs can be set using the Set Outputs and Reset Outputs commands.

For details on additional discrete I/O options, see Using the Communication Digital I/O and Using

the Sensor Digital I/O.

It is highly recommended that the I/O Bit Monitor be used for debugging wiring of these discrete

inputs.

5.1.5 Sensor Digital I/O

5.1.5.1 Using the Sensor 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 Sensor Digital I/O.

The Sensor Digital I/O has eighteen digital inputs and eight digital outputs. The inputs on the

Sensor Digital I/O can be used for the following:

• The inputs can be used to trigger event sequences using the Input to Event table. That is, rising

edges and falling edges on these inputs can be set up to start any event sequence on one or

more axes. Refer to Input to Event table for details. This ability is available unless the

Communication DI/O is used in Input to Event mode.

• The inputs can be used to control transitions between Steps in the Event Step table through the

Single Input (I, i, O, and o) and Multiple Inputs link types. In this case, the transition is allowed or

disallowed by the link type, but an event sequence must already have been started before the link

types will be evaluated. This differs from using the Input to Event table, which actually begins an

event sequence.

• Inputs 16 and 17 can be used as either an edge or quadrature counter. See Using Counters for

details.

• When used in combination with a Communication DI/O using Parallel Event mode, the inputs can

be used as part of that mode. Refer to Parallel Event mode for details.

The outputs of the Sensor DI/O can be used for the following:

• The outputs can be set using the Set Outputs and Reset Outputs commands.

The use of this I/O is configured using the Sensor Digital I/O dialog box. To open this dialog box:

1. On the Tools menu, click Module Configuration.

2. In the Slots list, click the Sensor Digital I/O item. This item will be available only if the Sensor

Digital I/O module is installed.
