7616 separate status indicators:
-3808 Bi-color LEDs or
-224 seven segment displays
The state of the status indicators can be written to or read from the
RKU5 Control Unit.
Data communication between the RKU5 Control Unit is carried out
via asynchronous (RS-232) serial links by using ANSI X3.28 protocol.
2. TECHNICAL DESCRIPTION

3. OPERATION
3.1 INDICATOR ADDRESSING
Note: Knowledge of the ANSI X3.28 protocol is assumed.
Data communication between the RKU5 Control Unit and the Control
Center (MicroSCADA) is done via asynchronous serial link (RS232)
by using the ANSI X3.28 communication protocol (see cable information
on Figure 3).
There are two address areas for writing and reading the states of the
indicators, one for seven segment displays and one for LED indicators.
The addresses for the LED indicators are formed using the formula:
write address of the LED-indicator =
(bus cable - 1) x 14 x 34 + (card number-1) x34 + pin + 5000
where
- bus cable is the cable number to which the LCM driver
of the LED indicator is connected (bus cables
are numbered from 1 to 16)
- card number is defined by the board-number-select-jumper
on the LED Control Module (1-14, see Figure 4)
- pin is the pin number of the LCM to which the LED indicator
is connected (1-34)
The led addresses starts from 5001 dec. and continues to 12617 dec.

KUUMIC OY
NETWORK CONTROL MIMIC BOARD

Examples:
- first LCM addresses are from 5001 dec. to 5034 dec.
-bus cable = 1
-card number = 1
First address = (1-1) * 14 * 34 + (1-1) * 34 + 1 + 5000
= 5001 dec.
Last address = (1-1) * 14 * 34 + (1-1) * 34 + 34 + 5000
= 5034 dec.
- 84th LCM addresses are from 7823 dec. to 7856 dec.
-bus cable = 6
-card number = 14
First address = (6-1) * 14 * 34 + (14-1) * 34 + 1 + 5000
=7823 dec.
Last address = (6-1) * 14 * 34 + (14-1) * 34 + 34 + 5000
=7856 dec.

The addresses for the Display Control Modules (DCM) are formed using the
formula:
write address of the DCM =
(bus cable - 1) x 14 + DCM number + 4700
where
-bus cable is the cable number to which the DCM
is connected
(bus cables are numbered from 1 to 16)
-DCM number is defined by the board-number-select-jumper
inside the DCM Control Module (1-14, see Figure 5)
The addresses for the DCM starts from 4701 dec. and continues to 4924 dec.
Examples:
- first DCM address
-bus cable = 1
-DCM number = 1
address = (1-1) * 14 + 1 + 4700
= 4701 dec
- 15th DCM address
- bus cable = 2
- DCM number = 1
address = (2-1) * 14 + 1 + 4700
=4715 dec

3.2 WRITE LEDs
Write operations are done by using "unprotected block write"- or "protected
block write"-commands.
The RKU5 handles both "unprotected" and "protected" operations in a similar
way. Only word addresses are used.
The data bit 0 represents the LED state, value 0 means the LED is off (not
illuminated) and value 1 means the LED is on (illuminated).
The data bit 1, value 1 sets the LED to blink appr. twice a second.
The RKU5 ingnores data bits 2 through 15 in write messages.
Multiple LED states can be written by one command. The only limit is set
by the ANSI X3.28 protocol, which limits the length of the data field.
Example of write message:
address= 6201 (decimal)
data = 0001
The address above selects the LCM, which is connected to the bus cable
number 3 (bus cable connected to 3th Display Bus Driver board) and has
the card-number-select- jumper in position 8 (card number is 8). The LED
connected to pin 11 on the selected LCM will be illuminated after the
message has been sent. The data value 2 sets the same LED to blink
approximately twice a second.

3.3 READ/WRITE SEVEN SEGMENT DISPLAYS
Write operations are done by using "unprotected block write"- or "protected
block write"-commands.
The RKU5 handles both "unprotected" and "protected" operations in
a similar way.
The Display Control Module needs two different memory areas.
The addresses for the DCM´s data starts from 4701 dec. and continues
to 4924 dec.
In addition to this DCM requires parameter area for the decimal points and
minus sign. The addresses for the DCM´s parameters starts from 2219 dec.
and continues to 2442 dec.

data address = 4702 dec.
data = 100 dec.
The 2nd DCM will display 10.0
parameter address = 2233 dec.
data = 0007 dec.
data address = 4715 dec.
data = 32768 + 789 dec.
The 15th DCM will display -.789
parameter address = 2442 dec.
data = 0008 dec.
data address = 4924 dec.
data = 10 dec.
The last (224th) DCM will display 0010

3.4 LED-TEST
The address 5000 dec is reserved for the nonvolatile RAM-memory
initialize and LED-test.
At the beginning the nonvolatile RAM memory should be cleared by
writing the value 7 dec. to the address 5000 dec.
The following table shows the test address definition:
VALUE (dec.) EFFECT
0 all LEDs and segments are OFF
1 all LEDs and segments are ON
2 all LEDs blinking, slow rate
3 all LEDs blinking, high rate
4 every odd LEDs ON
5 every even LEDs ON
6 finish test
7 initialize nonvolatile ram-memory
When writing value 0 to the address 5000 dec., all the LEDs turn off.
They are off appr. one minute, and after that they turn back to the state
they were before the test.
When writing value 1 to the address 5000 dec., all the LEDs turn on
(illuminate). They illuminate appr. one minute ,and after that they turn
back to the state they were before the test.
The state of LEDs can be changed before the minute is over by writing
to the address the opposite value.

4. INSTALLATION
Set CPU and Display Bus Drivers DIP-switches (Figure 6 and 7)
Connect the communication cable between the RKU5 control unit COM2
and the communication port of the MicroSCADA (see Figure 2).
Connect LEDs and LED power supply to the LED Control Modules
(Figure 8 and 9)
Connect IDC ribbon bus cables between RKU5 control unit and LCMs.
The IDC ribbon bus cable has 2 - 15 connectors. The number of connectors
depends on the number of LCMs and DCMs. All connectors are connected
in parallel. Set card-number-select-jumpers (Figure 4 and 5). Make sure
that all LCMs and DCMs for the same bus cable are jumpered to a different
number. Install clock and data pull up jumpers (S15 and S16) to the last
LCM of the bus cable .
Note! The LCMs and the DCMs can´t be connected to the same bus cable.
Connect the RKU5 control unit and mimic board power supply on.
Use the MicroSCADA to clear NV-RAM and turn all LEDs on by writing test address
5000 dec. Check that all LEDs illuminate.
Check that all LEDs are in the correct addresses by writing them on and off
one at a time. Check the DCMs in the same way.
