Basic Operation

When used in this mode, each digital input on the Communication Digital I/O corresponds to a

row of the Input to Event table. The row has an entry for each axis. Each entry is used to specify

a step the axis will execute in the step when the input is activated. If an axis is not to respond to

the input then its entry should be -1. Refer to that topic for further details. One input can trigger as

many as eight axes to start executing different sequences of steps at the same time. Each axis

can be thought of having its own sequence of steps that may be run independently of other axes’

step sequences. Modifications to the normal Input to Event table behavior are discussed below in

the Single-axis inputs and Non-linkable inputs sections.

Each time a transition is made on DI/O 0-15, the Acknowledge bit (CPU output 1) will be

toggled. This bit will also toggle when the Run/Stop bit (CPU input 0) rises or falls.

Configuring Input to Event Mode

This is done using the Input to Event Mode Options dialog box. To use this dialog box:

1. On the Tools menu, click Module Configuration.

2. In the Slots list, click the Comm Digital I/O item.

3. Click Slot options.

4. In the DI/O mode list, click Input to Event.

5. Click Mode options.

6. Select the desired options.

7. Click OK.

8. Click Update RMC.

9. The Update Module Configuration dialog box will be displayed to indicate the progress. If the

module could not be reset automatically, you may be prompted to reset the module manually.

Single-axis Inputs

As described in the Input to Event table topic, a single input transition normally affects all axes

that have an entry for that input transition. However, you may also configure each individual input

to affect only a single axis. To make an input affect only a single axis, select the Single-axis

input check box. For information on selecting an axis, see the section below titled Axis Select

Bits.

An example application where this is useful would be where the same operation can be done on

one of several axes using the same button and input. In this application, one might allow the user

to set the Axis select bits using a rotary or toggle switch, and then make the input coming from

the button a Single-axis input. Then, in the Input to Event table, the input transition row would

have Step numbers for each axis, but only one would be executed depending on the Axis select

bits at the time of the transition.

Non-linkable Inputs

This area operates similarly to the Single-axis inputs area described above. By selecting the

check box next to an input, you are modifying the behavior of the Input to Event table for both

transitions of that input. In this case, Non-linkable inputs will result in the command in the Event

Step referenced by the Input to Event table to be executed on the axis, but the Event Step

sequence will not be started, nor will any current Event Step sequence on that axis be

interrupted.
