JOB Select Inputs
These inputs are used to select a JOB number from the
external PLC or other host controller if serial communication
is not being used. These inputs represent Binary Coded
Decimal (BCD) that translates to 3 digits, each digit
represented as a 4-bit binary code. The system inputs
shown in Figure 6 are used to select and enter a JOB
number. The JOB Select inputs are used in conjunction
with the GUN Mask inputs to determine which GUNs will
accept the JOB number represented by the total of the
active JOB Select Bits.
Example:
JOB #25 is Requested
Decimal Number = 25
Most Significant Digit (100's) = 0 = binary 0000
Middle Significant Digit (10's) = 2 = binary 0010
Least Significant Digit (1's) = 5 = binary 0101
JOB numbers can be entered into the JOB Queue at any
time regardless of the operating mode.
These signals are used in conjunction with the GUN MASK
inputs to determine which GUN(S) will receive the JOB #
as input by the program select inputs. The JOB SELECT
inputs must be present at the time that the JOB SELECT
STROBE signal is activated.
The basic sequence for selecting and entering JOB
numbers is:
1. Select and hold high the appropriate JOB SELECT
input bits.
2. Select and hold high the appropriate GUN MASK
input(s). This can be performed simutaneously with the
JOB SELECT input bits.
3. Pulse the STROBE input.
4. Return all inputs to the low state (0 VDC).
