Using the RMCWin software, these outputs may be marked to be user-controlled instead of
being used for the above default assignments. User-controlled outputs are set and cleared
from the Event Step table.
The following features of Input to Event mode add complexity to the mode, and are necessary only for a
small number of applications:
• Using RMCWin, any of the Trigger inputs can be marked as Single-axis inputs. When an edge
occurs on a Single-axis input, only one field in the Input to Event table is used. This field is given
by the row of the input edge that took place and the axis selected by the three Axis Select inputs
(CPU input 1, DI/O inputs 16-17).
• Note: This feature is not required in most cases where only a single axis is to be affected by an
input. Most often this can be done by leaving all axes’ event step numbers blank in the Input to
Event table except the one axis that is to be affected.
The following table shows how to select an axis with these inputs:

• Using RMCWin, any of the Trigger inputs can be marked as Non-linked inputs. When an edge
occurs on one of these inputs, the Input to Event table is still referenced to find the axes that have
Event Step numbers. However, instead of starting an event sequence on the axis, only the
command from the event step is given to the axis and any pre-existing event sequence continues
execution.
The following general steps must be taken to set up a system using Input to Event mode:
1. Design the System
Designing the system begins with selecting the appropriate method of communication. First,
decide whether one of the RMC’s field bus solutions fits your application, and if you decide to use
digital I/O, then decide which of the communication modes fits your application.
If you decide to use digital I/O using Input to Event mode, then you must design the wiring of the
system, the event step table, and the input to event table.
2. Program the Event Step Table
Programming the Event Step table is described in the RMCWin online help. The event step table
will hold the majority of the controlling logic. Be sure to save your Event Step table both in the
RMC Flash memory and on disk from RMCWin.
