Physical Inputs Description
Keyboard A1 - H4 Keyboard Location Codes
Rack 1 INPUT 1 through 4 PCIO #1 1st bank.
Rack 2 INPUT 1 through 4 PCIO #1 2nd bank.
Rack 3 INPUT 1 through 4 PCIO #2 1st bank. Requires use of a second PCIO board.
Rack 4 INPUT 1 through 4 PCIO #2 2nd bank. Requires use of a second PCIO board.
Accessory Inputs 1-4 PCIO #2 2nd bank. Requires use of a second PCIO board.
External Inputs 1-16 These represent “virtual” physical inputs. They are normally
used by a communications device attached to a serial port to
allow a logical input’s state to be changed..
External Outputs 1-16 A device attached to a communications channel to display the
state of an input normally uses these.
Stable Weight, Keyboard
Locked These inputs are used by the controller internally and should not
be mapped..
Digital Outputs
This selection allows changing the mapping for the digital outputs. The Logical is mapped to the
Physical layer. This means one (1) logical output may be mapped to several different physical
outputs. For example the Logical Output “General Alarm” may be mapped to Rack 1 Output 4,
Rack 2 Output 6 and Rack 4 Output 2 allowing different external processes to know that a
problem has occurred with the controller.
List of Logical Outputs
Name Description
Fault This output indicates that a condition occurred that is serious enough to
stop feeding. This is the Logical “or” of all outputs and inputs qualified
for FAULT.
Warning A condition has occurred that needs attention but is not serious enough
to stop the feeder. This is the Logical “or” of all outputs and inputs
qualified for WARNING
High Feedrate Output indicating that the feedrate has exceeded a set limit for a set
time. The settings for this parameter is in the Limit Switches on page
24.
Low Feedrate Output indicating that the feedrate has been below a set limit for a set
time. The settings for this parameter is in the Limit Switches on page
24.
High Deviation Output indicating that the difference between the feedrate and the
setpoint has lag set limits for a set time. The settings for this parameter
is in the Limit Switches on page 24.
Low Deviation Output indicating that the difference between the feedrate and the
setpoint has lag set limits for a set time. The settings for this parameter
is in the Limit Switches on page 24.
High Setpoint Output indicating that the setpoint is above the High Feedrate Limit. The
Setpoint will not be allowed to go above the High Setpoint Value and
will be set to that value when the logical input Limit Setpoint is enabled.
The settings for this parameter is in the Limit Switches on page 24.
Low Setpoint Output indicating that the setpoint is below the Low Setpoint limit. The
setpoint will not be allowed to drop below the Low Setpoint Value and
will be set to that value when the logical input Limit Setpoint is enabled.
The settings for this parameter is in the Limit Switches on page 24.
