List of Unit Combinations
NOTE: It may be necessary, after selecting the units, to update the decimal point selection values.
Even if no changes to the decimal points are necessary, you should at least look at each
decimal point option to insure the proper display of values.
Design Capacities
These parameters are use to set several internal scaling values in the controller.
Feedrate
This parameter normally represents the highest feedrate that can be obtained by all of the
feeders attached to the system.
# of Ports
This parameter is the number of Fastcom 422/4-104 communication ports that have slave feeders
attached.
# of controllers
This parameter is the number of MC³ feeders attached to the system. This is used by the menu
system to reduce the amount of button pushes required to reach a specific controller.
# of Recipes
This parameter is the total number of recipes used. If only 25 recipes are used this limits the
cycling time when choosing a recipe by eliminating the 75 that are not used when selecting
recipes.
Decimal Points
Internally the MC³ Controller uses floating-point numbers. Any changes to the decimal point
setting affects only the display of the values, which will be rounded appropriately.
NOTE: Note that the maximum number of decimal places is four and is used for display purposes
only.
Comm Parameters
Serial Communications provides the means to exchange information between the MC³ Controller
and another device. For example, data in the MC³ Controller can be exchanged with devices
such as SuperBridge, for PLC connectivity. The rules and format of the data exchange is
described in a separate publication, Merrick Serial Protocol Specification.
Please refer to Merrick’s web site at www/merrick-inc.com/mct/ for information concerning the
Modbus ASCII Communications Specifications.
CAUTION: Failure to program communications correctly can result in the operational failure of serial
communications.
For Baud Rate, Data Bits, Stop bits and Parity parameters, simply touching the button for the
corresponding parameter will toggle through the list of available settings.
Baud
The Baud Rate is the speed at which data is transmitted across the serial communications lines.
Available baud rates are:
