Changing the Personality 7-9
False True False, corresponding to the binary number 010, which is equal to decimal 2. If
Inputs 4, 1, and 0 are all True (binary 111 = decimal 7) then Download Sequence 7 is
invoked.
The BCD ("Binary Coded Decimal") -encoded invoke works the same as the
binary-encoded invoke, except that the Download Invoke Inputs are interpreted as a BCD
number rather than a binary number. In a BCD number bits 0 through 3 are the ones digit
and bits 4 through 6 are the tens digit. So a BCD 1010011 is equal to decimal 53; the tens
digit is a 5 (binary 101) and the ones digit is a 3 (binary 0011). Invalid BCD numbers (e.g.
1011100) produce undefined results.
For example, suppose you have activated all 8 Inputs; i.e., parameter 36 is 255 (binary
11111111) and parameter 37 is 768 (binary 1100000000 - only bits 8 and 9 set). Input 7
becomes the trigger. Inputs 0 through 6 are interpreted as a BCD number; to invoke
Download Sequence 49 you would set the inputs to 1001001, for example via a pair of
BCD-encoded thumbwheel switches set to the decimal number 49.
If you activate only one Digital Input it becomes a trigger for Download Sequence 0.
Bit 10 affects the Download Invoke feature as follows: when bit 10 is set (i.e. 1) the
Automove System adds 100 to the i.d. of the invoked Sequence. For example, instead of
invoking Download Sequence 49 in the above example, the System would invoke
Download Sequence 149. Bit 10 affects all three invoke modes discussed above
(one-for-one, binary-encoded, and BCD-encoded) but does not affect front-panel invokes.
Thus, by setting bit 10, you can invoke 10 different Download Sequences from the front
panel, plus as many as 128 other Sequences (numbered 100 through 227) from the Digital
Inputs.
For more information, see Chapter 8.
Example: suppose parameter 36 is set to 255 (thus enabling triggering on all eight Inputs),
and parameter 37 is set to 3 (i.e. bits 0 and 1 are ones, bits 2 through 7, 8, and 9 are zeros).
Furthermore, assume parameter 38 is set to 255, meaning that all eight Inputs are Low
True. A High-to-Low transition on Input 0 or Input 1 causes Digital Output 0 or 1 to
toggle, respectively. A High-to- Low transition on Inputs 2 through 7 invokes Download
Sequence 2 through 7, respectively.
