Counter / batch controller XX-2061 for pulse sensors
Description
The field display series XX-2061 is designed for pulse
counting and batch control in applications where a
readability of 20 to 100 metres is required.
The incoming pulses are freely scaleable on display to
correspond the wanted number value, e.g. 1 incoming
pulse equals to 5,34 on display. Display memory
stores the calculated value in memory for one week
after power supply break.
The preset function makes it possible to use the
counter as a batch controller as well. Counting can be
done up- or downwards from the preset value. Alarm
relays may control other devices. New counting can be
started automatically or manually by external key.
Large field counters are part of a larger display series
where by changing the input/output cards the display
can be modified to other input values such as
temperature, serial or frequency input. Two power
suppliy possibilities, one for 85..240 VAC and the
other for 24 VDC, both galvanically isolated from input/
output. Readability of the displays is also good outdoors
if exposure to direct sun light is prevented by using a
sun cover. Case protection is IP54-IP65.

Programming
In the programming state the sensors, alarms and
scaling of pulses are chosen. The programming state is
achieved by pressing the star buttons and arrow but-
tons simultaneously for about 2 seconds. The text
Pulse appears in the display. With the arrow keys you
move upwards in submenu or in basic menu. By the
desired function you move to the arrangement state
with the star button and returned to the main menu
with same button. When all arrangements have been
made,you move to SAVE - UNDO - menu, with star
key. SAVE accepts with the button ➤the changes
and UNDO cancels the changes.

Selection of the direction for the relay function.
When connecting the power supply to the counter the PO res setting can
prevent the start of the counting if Nc has been selected as the direction for
the alarm relay function.In this case the counting will not start until after the
Reset function.
Selection of the counting direction: upwards or downwards.
Change of the counting direction of counter via an external contact on the
2000-I/O card.
The start value (Start) of the counting or the alarm limit value (Limit) can be
changed directly in the display state without entering the configuration state.
When the loop function is selected (On), the counter resets and at the same
time starts a new count automatically when the alarm limit is reached.
Interlock of the external reset contact during counting. Reset can be
performed only after the alarm limit has been reached. Does not prevent the
reset via front panel.
When resetting the counter the first push of the reset button displays the value
set in the Adjust state (Start or Limit). The second push resets the counter.

Serial output RS485/RS232 (option)
Meter may be provided with optional serial output and
you can read measurements by e.g. PC. Display
programming can not be made via serial port. Addi-
tional card provides serial signal RS232 and RS485,
only one of those can be selected.
Serial signal is isolated from both input signal and
power supply. Meters with RS485 can be max. 31 in
same loop and longest distance 1000m. RS232 en-
ables only connection of two devices and max. dis-
tance 10..20 m.
In programming stage you can first select card type
(serial) mounted to slot B or C and then address and
Baud rate. Baud rates are: 300, 1200, 2400, 4800,
9600, 19200 and addresses 0...127.
Accept selection and move forward by ➤-key. You
come back to previous level always by ★-key.
Program remembers card type mounted, if ithas been
saved by save command when leaving program. In
case you can not choose serial card, slot has
automatically recognized card (plug and play).
Terminal connections:
By serial signal RS485 last unit must be
terminated by 110 ohm resistor. you can
make termination at terminal connectors
or by connecting jumper J1 to ON-
position.

Serial protocol (SCL):
MESSAGES: When asking the measurement data
from the panelmeter 2061 through the serial port, a
command sequence which is in accordance with the
SCL protocol is used for the inquiry:
(Only the measurement results can be asked from the
panelmeter 2061)
<ADDR+80h>COMMAND STRING<ETX><BCC>
<ADDR>
The first byte character to be sent contains the ADDR
(0..127) of the address of the destination device and at
the same time functions as the start bit of the com-
mand. 80H (in a decimal 128) with which an uppermost
bit is set as the number one is added to the address.
COMMAND STRING: When measurement data is
requested, the actual command is: MEA CH 1 ? , in
which 1 means the channel number. (there is only one
channel in the panelmeter 2061 so the number is
always 1).
<ETX>
<ETX> mean the end mark of the command,
ASCII character 03h.
<BCC>
Finally the checksum is calculated using the XOR
operation on the byte characters of the actual com-
mand including the ETX. In the example the ASCII
codes have been presented in hexadecimal.
e.g.
One wants the measurement result from the display
unit address 1. To the channel an inquiry is sent:
MEA CH 1 ? (ASCII codes shown for <BCC>
calculation)
M E A C H 1 ?<ETX> <BCC>
4Dx45x41x20x43x48x20x31x20x3F x03 = 6F
(Presented the XOR operation with a character x)
(ASCII code 20h corresponds to space character)
So the following bytes are sent to 2061:
81 4D 45 41 20 43 48 20 31 20 3F 03 6F
RETURN MESSAGE: The answer from the panelmeter
2061 is obtained in the following format:
<ACK>RETURN MESSAGE<ETX><BCC>
<ACK>
The first byte of the answer contains the start of the
answer <ACK> (ASCII-code 06h) and the answer
itself, endmark <ETX> (ASCII- 03h) and the checksum
of the answer which is calculated from all the byte
characters of the answer including <ACK> and <ETX>.
2061 counts the checksum in which case the receiver
does not need necessarily to care about it,
e.g.
e.g. When a measurement result is for example 21.3,
it will be obtained from the panelmeter in the following
form
<ACK> 2 1 . 3 <ETX> <BCC>
Answer: 06 32 31 2E 33 03 1B

The field display series is modular and easy to as-
semble. According to customers wishes. The basic
construction consists of mother board with tree slots,
A, B and C. Slot A determines meter type and provides
always input signal. Slot B and C are interchangeable.
As factory delivery input signal is always installed into
slot A , mA output into slot B and alarms into slot C. In
case of f.ex 4 alarms and relay card with 2 change-over
contact (2 + 2 relays) are used, you must place second
Slots A-C
Change of meter
type:
Input card is placed always
to slot A. By changing input
card you can get an other
type of meter. You can
change meter with pulse
input to meter with current
input, thermocouple, strain
gage etc.
Additional slots:
Additional cards provide
output 4..20 mA, alarms,
serial interface, BCD output
etc. Meter data sheet
dictates possible combina-
tions. grey connectors allow
line voltage 110..240 VAC
(relay contacts).
Power supply:
There are two different mother
boards power supply 85..240
VAC and 12..32 VDC. VDC-
mother board accepts
24 VAC. Connectors are
colour coded.
relay card into slot B. If you accept only closing or
opening relay contacts, you need only one relay card
with 4 relays placed into slot C. The slot B is now
usable for other optional outputs.
You can have different types of meters by only
changing the input card in slot A. Data sheet of each
type of meter dictates the possible combinations.
Recalibration of card is not needed; only scaling and
other settings must be set by front panel keys.
All cards have calibration
memory
