Software Overview
The MC³ software consists of three (3) primary parts consisting of the BIOS (Basic Input / Output
System) a register database and the actual application software. The software has been
designed to utilize the hardware fully without requiring a large amount of training to operate. The
user interface has been designed to provide you with maximum flexibility with minimum input.
Application Software
Application Software is written for each specific type of "job" that the controller is to perform. This
software will allow you to turn on and off different modes of operation, which allows you to
configure the software for your specific process
BIOS
The BIOS is the portion of the software that directly manipulates the hardware. It is the interface
between the application and the hardware.
Register Database
The Register Database is a set of variables used in the software application. It is provided to
allow structured access through Serial Communications to variables used in the MC³. A numeric
listing of registers for each application is available from Merrick. Procedures for using Serial
Communications to access the register list are also provided in the Merrick Serial Protocol
Specification.
Digital I/O Mapping
The MC³ allows configuration of the digital inputs and outputs to the system's requirements. By
allowing mapping of the I/O, the MC³ gives a great degree of flexibility in design of the system.
CAUTION: This feature is a very powerful tool that should be used with extreme care. For most
installations, the default settings should be used.

is cleared.
The fourth line Displays the running condition of the controller.
Ready –All feeders associated with the current recipe are online AND
There are no fatal communication errors AND
All feeders are ready (The associated Ready output for each feeder is enabled.) AND
The Feeder Block logical input is disabled AND there are no FAULTS.
In Control –The Ready (same as above) logical output is enabled AND Run Permission logical
input is enabled.
Good Feed –All feeders associated with the current running recipe are feeding good. (The
associated output for Feed Good is enabled in each running feeder.) AND
The In Control logical output is enabled (same as above). AND

Master Setpoint
Touching this button provides access to the Setpoint Screen. A Setpoint Password may be
saved to restrict access to this screen. See the section Password Settings on Page 37 for setting
and modifying password.
On the Setpoint Screen, the Setpoint Mode Button at the top left will indicate the Setpoint Mode.
Touching the Setpoint Mode Button will change the Setpoint Mode to the next mode in the order
of the list:
Local
When this mode is selected, direct entry of the Feedrate setpoint is available. This setpoint is in
engineering units for feedrate.

MC³ 90.10.EX O&M Manual -11 -
Analog
This Setpoint mode allows the setpoint value to be input through the Analog Input in relation to
the Maximum Feedrate. For example, if a 50% input signal (12mA when the input is 4-20mA) is
being read from the Analog Input, and the Maximum Feedrate Capacity is 40.00 lb/min, then the
Setpoint will be 20.00 lb/min.
Ratio
This method scales the External Feedrate setpoint as a percentage of the incoming analog input
signal. Scaling is the same as Remote Analog. This allows multiple systems to be connected to a
single signal with each system assigned a particular percentage of the signal as a setpoint.
For example, three systems are to be used configured to provide material to a process using one
analog input for control. System number one provides 25%, system number 2 provides 35% and
system number 3 will provide 40% of the material needed for the total process. When the
setpoint changes for the process all three systems will properly scale for the new setpoint.
Serial
This setpoint mode allows the MC³ Controller to receive a setpoint from a remote device through
the serial port such as a computer or a PLC/SuperBridge Controller. This method requires that
the remote device be connected to the controller via a serial port.
NOTE: When the controller is to be used in SuperBridge or any other system, which transmits
setpoint information using Serial Communications, the Remote Serial mode must be selected.
The rules and format of the data exchange is described in a separate publication, Merrick
Serial Protocol Specification.

MC³ 90.10.EX O&M Manual -12 -
