Event Input Settings

• The number of event inputs that is supported depends on the model of the Digital Controller.
E5CC: Up to 4 event inputs
E5EC/E5AC: Up to 6 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:
• Controllers without event inputs for which the Number of Multi-SP Points parameter is not set to
OFF
• 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
