Non-serial Controls

General information about non-serial controls on CBWs
MILNOR non-serial CBWs use a Motorola 6800 microprocessor. The control includes a number of boards for I/O and memory. Since the processor board has only "scratchpad " memory, a separate memory board is used for customer stored data. All boards are found in a card cage mounted in the Miltron. Additional boards include: 32 relay output boards (with reed relays as outputs), input board with 12VDC inputs and a analog to digital (A to D) board for converting the signal from the CONWA load cell.

OUTPUTS - The control shipped standard with 16 user configurable outputs (C-Bits). Options include adding more outputs for a total of 80 C-Bits.

DATA PASSING - Mk7c software allows the passing of goods data and adds an additional 32 outputs for data passing. Outputs for goods code (64), customer code (64), wash formula (16), destination code (16) and weight (up to 204.8 lbs or Kgs with bit values of .1, .2, .4, .8, 1.6, 3.2, 6.4, 12.8, 25.6, 51.2 and 102.4 - a total of 11 outputs) are included.

MEMORY - The total program memory space is limited by the Motorola processor. For this reason, features became limited at the end of this controls history. Software changes were also difficult because the 6800 was programed in assembly language without the use of a compiler, as we use today.
