Single Unit Operation
The operator can monitor the control locally via
the keypad and display located inside the control
housing . The serial interface extends these
monitoring activities to a remote location . The
connection of a remote display terminal is
straightforward. The ID number of the control
should be set to “0” (line 32 in the program table).
When power is applied to the CBPC-3590 control,
it will start a continuous serial transmission of the
count:
CBPC-3590 R: CNT. 123456
when in the run mode.
The function keys (1,2,3,6,7, & 8) are used to scroll
down through the eight RUN mode lines. For
example:
terminal ‘1’ CBPC-3590 R: CNT. 123456
terminal ‘2’ CBPC-3590 R: Mov.Pst. 600
terminal ‘3’ CBPC-3590 R:
E.W. 50
terminal ‘6’ CBPC-3590 R: BCH. 100
terminal ‘7’ CBPC-3590 R: BCH.Pst. 0
terminal ‘8’ CBPC-3590 R: Bd. 25
In the RUN mode, the numbers 1,2,3,6,7, & 8
cause new lines to be transmitted.
We have now seen how the CBPC-3590 control
works for remote viewing; we will now see how
programming may be done from a remote location .
You may program only one CBPC-3590 control
at a time . If the unit is in the program mode via
the keypad then it will not respond to the serial
input. To enter the PROGRAM mode you must first
send the RUN/PGM (“P”) character. The control
will “answer” by transmitting the LOC entry line as
shown below:
terminal ‘P’ CBPC-3590 R: LOC 0
The control remains active (in the RUN mode)
until the proper LOC combination is entered . Each
numeric entry is entered from right to left
“calculator style” . The character sequence
1-0-0-0 would produce the following display on
the terminal:
terminal ‘1’ CBPC-3590 R: LOC. 1
terminal ‘0’ CBPC-3590 R: LOC. 10
terminal ‘0’ CBPC-3590 R: LOC. 100
terminal ‘0’ CBPC-3590 R: LOC. 1000
When this combination is correctly entered with
the down cursor (‘D’ character), the control exits
the RUN mode and enters the PROGRAM mode
and returns with the following.
terminal ‘D’ CBPC-3590 P: h. ---
Note that the PROGRAM (‘P’) prompt is now
shown. You are at the top of the PROGRAM table
(line 1) as shown on page 11. Once the
PROGRAM mode has been entered it is pos-
sible to program any line in the table . Refer to the
COMMAND CHARACTER table for keypad
equivalent serial characters . A programming
example is shown below:
terminal ‘C’ CBPC-3590 P: Mov.Pst. 000
terminal ‘6’ CBPC-3590 P: Mov.Pst. 6
terminal ‘0’ CBPC-3590 P: Mov.Pst. 60
terminal ‘0’ CBPC-3590 P: Mov.Pst. 600
The first serial entry (‘C’) clears the data field for
the current line. As can be seen in the COMMAND
CHARACTER table, this character mimics the
RESET/CLEAR key. Numeric data entry is
self-explanatory .
Multiple Unit Operation
For multiple unit systems (up to 999) a special
addressing scheme is implemented in order that
no conflicts arise on the serial bus. Each unit is
given a unique address (ID number entered on line
32). Such a system application is shown on page
16. All units are programmed with the same baud
rate and parity . It is advised that the initial ID
number programming be done
before the units
are bussed together .
