Using Event Inputs

5-4-1

Event Input Settings

• Events can be used on models that have event inputs.
The number of event inputs that is supported depends on the model of the Digital Controller.
E5EC/E5EC-B/E5AC: Up to 6 event inputs
E5CC: Up to 4 event inputs
E5GC/E5CC-B: Up to 2 event inputs
E5DC: Up to 1 event input
* The E5DC-B does not have models with event inputs.
• Event inputs can be used for switching between RUN and STOP, switching between automatic and
manual operation, starting/resetting the program, inverting direct/reverse operation, switching the SP
mode, executing/canceling 100% AT, executing/canceling 40% AT, enabling/disabling setting
changes, enabling/disabling communications write, canceling the alarm latch, and switching the
multi-SP number.

How to Use the Multi-SP Function

The multi-SP function allows you to set up to eight set points (SP 0 to 7) in the Adjustment Level. The
set point can be switched by operating the keys on the front panel or by using external input signals
(event inputs).
 Using Event Inputs
The following table shows the relationships between the ON/OFF status of multi-SP number
switching bits 0 to 2 and the set point.

SP 1
SP 2
SP 3
SP 4
SP 5
SP 6
SP 7
Note: Any bits that are not assigned to event inputs are treated as being OFF.
 Using Key Operations
You can select any of the set points 0 to 7 by changing the set value of the Multi-SP Uses parameter.
The Multi-SP Uses parameter display conditions are as follows:
• Digital Controllers without event inputs for which the Number of Multi-SP Points parameter is not
set to OFF
• Digital Controllers with event inputs for which the Number of Multi-SP Points parameter is not set
to OFF and the Event Input Assignment 1 to 6 parameters are not set to Multi-SP switching bits 0
to 2
The following table shows the relationship between the Multi-SP Uses parameter set value and the
selected set point
