Counter / batch controller 2800-2061 for pulse sensors
Description
The field display series 2800-2061 is designed for
pulsecountingandbatchcontrolinapplicationswhere
a readability of 20 to 100 metres is required.
Theincomingpulsesarefreelyscaleableondisplayto
correspondthewantednumbervalue,e.g.1incoming
pulse equals to 5,34 on display. Display memory
stores the calculated value in memory for one week
afterpowersupplybreak.
The preset function makes it possible to use the
counterasabatchcontrolleraswell.Countingcanbe
doneup-ordownwardsfromthepresetvalue. Alarm

Serial output RS485/RS232 (option)
Metermaybeprovidedwithoptionalserialoutputand
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,
9600,19200andaddresses0...127.
Accept selection and move forward by -key. You
come back to previous level always by -key.

Terminalconnections:
By serial signal RS485 last unit must be
terminated by 110 ohm resistor. you can
maketermination atterminalconnectors
or by connecting jumper J1 to ON-

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:
(Onlythemeasurementresultscanbeaskedfromthe
panelmeter2061)
<ADDR+80h>COMMANDSTRING<ETX><BCC>
<ADDR>
ThefirstbytecharactertobesentcontainstheADDR
(0..127)oftheaddressofthedestinationdeviceandat
the same time functions as the start bit of the com-
mand.80H(inadecimal128)withwhichanuppermost
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
which1meansthechannelnumber.(thereisonlyone
channel in the panelmeter 2061 so the number is
always1).
<ETX>
<ETX>meantheendmark ofthecommand,
ASCIIcharacter03h.
<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
codeshavebeenpresentedinhexadecimal.
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)
(ASCIIcode20hcorrespondstospacecharacter)
So the following bytes are sent to 2061:
81 4D 45 41 20 43 48 20 31 20 3F 03 6F
RETURNMESSAGE:Theanswerfromthepanelmeter
2061isobtainedinthefollowingformat:
<ACK>RETURNMESSAGE<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)andthechecksum
of the answer which is calculated from all the byte
charactersof theanswerincluding<ACK>and<ETX>.

You can have different types of meters by only
