Linear input
If the input is standard current or voltage, such as the output of the transmitter of level, pressure and temperature, the
lower limit of linear input LoL and the upper limit of linear input HiL should be set according to the nominal value. For
example, the instrument is connected with level transmitter, the output of the transmitter is 4-20mA and the
corresponding pressure is 0m-10m, the parameter should be set as follow:
Poin= - - -. –

LoL=0.0
LoL=0.00
HiL=10.0
HiL=10.00

For set range of input type parameter Sn, please refer to parameter table;
Example: if the input is 4-20mA, then Sn should be 16;
Input Type
For set range of input type parameter Sn, please refer to parameter table;
Example: if the input is 4-20mA, then Sn should be 16;
2.5.4 Transform output
The transform output of the instruments can be set to be 0-10mA or 4-20mA freely.
The transform range is determined by parameter LoL and HiL, Example:
The measured value is for temperature, set:
LoL=0
HiL=100
oP=4-20
When measured value is more than or equal to 100℃, the transform output is 20mA;
13
E-Mail:sales@e-caling.com or peter@e-caling.com
E-Caling(xiamen) Eelectronic Co.,LTD
When measured value is 50℃, the transform output is 12mA.
Note: As to linear current input (0-10mA, 4-20mA) and linear voltage input (0-5V, 1-5V), only one kind can
be chosen when ordering. Without specification, the linear voltage input (0-5V, 1-5V) is adopted; if the field
input is current, please parallel connect a precision resistor between the input terminals: if the field input is
0-10mA, please parallel connect a resistor of 500ohm, and set Sn to be 14; if the field input is 4-20mA,
please parallel connect a resistor of 250ohm, and set Sn to be 15.

b) When measured value is bigger than upper limit, the indicator is on and alarm contact close;

Figure 2
In order to avoid the frequent action of alarm output when the measured value is fluctuating at the critical
point of alarm, the parameter of alarm hytersis Hy is used.
When measured value increases to OUT1+Hy, upper limit alarm exports; when measured value
decreases to OUT1, the alarm does not stop; only when measured value is less than OUT1-Hy, the alarm
stops; refer to Figure 1.
When measured value decreases to OUT1-Hy, lower limit alarm exports; when measured value increases
to OUT1+Hy, lower limit alarm stops; refer to Figure 2.
3.2 Transform Output
The measured value can be converted to 0-10mA or 4-20mA standard current. The current output form is
determined by parameter oP and the transform range of measured value is determined by the parameters
LoL and HiL.
1)
When the input is linear, the transform output is the conversion output of the input signal. For example,
assume the input is 0-10mA (Sn=17) and transform output is 4-20mA (oP=4-20), when the input is
14
E-Mail:sales@e-caling.com or peter@e-caling.com
E-Caling(xiamen) Eelectronic Co.,LTD
0mA, the output is 4mA; when the input is 10mA, the output is 20mA.
When the input is thermocouple or RTD, the transform output range is determined by LoL and HiL.
2)
For example, if LoL=200, HiL=800 and oP=4-20, when the measured value is 200 o C , the output is
4mA; when the measured value is 800 o C , the output is 20mA.
3.3 Pillar-light simulated display
There are 20 segments pillar-light to display measured value, the display range is determined by LoL and
HiL:
When measured value is less than or equal to LoL set value, the pillar-light are all off;
When LoL set value<measured value<HiL set value, the segments of alighted pillar-light is proportional to
the measured value;
When measured value is bigger than or equal to HiL set value, t the pillar-light are all on.
3.4 Example
3.4.1 The instrument is used to control liquid level, and when the level is higher than 9m, upper limit alarm
exports; when the level is lower than 2m, lower limit alarm export. The liquid level transmitter is of
2-wire 4-20mA output and the corresponding value is 0-10m; the parameters are set as follows:
HL1=oN,
LoL=0.0
HL2=oFF,
HiL=10.0
Poin=---.-,
Hy=0.2
OUT1=9.0,

d) bAud: baud rate, range: 0-3, which means 1200, 2400, 4800 and 9600 respectively;
Hy, Sn, FiL, oP, Addr, bAud and status flag are all parameters of single byte, so they should be filled with ‘0’ in
high byte when written.
4.4 Communication instruction
4.4.1 Addressing instruction
When the host computer wants to communicate with some instrument, it should send an addressing
instruction first. The addressing instruction is single byte instruction, bit 1-8 is address and bit 9 is ‘1’
(Non-addressing instruction is ‘0’ ). The address of the instrument is determined by parameter Addr. The
instrument make a cooperation of the address in the addressing instruction and the address of its own, if
they are same, the instrument will start to communicate with the host computer. To the instrument in
communication, if it receives an addressing instruction in which the address is not the address of its own, it
will close the function of communication.
For example, if the Addr of the instrument is 3, when it is addressed, the format is as follows:
0
1
1
0

4.4.2 Survey read (E)
Instruction format: 45H
Return value: PV, SV, MV, 4FH 4BH (OK)
The low byte is at front and the high byte is behind, here SV is no meaning;
4.4.3 Read (R)
Instruction format: 52H + parameter code
Return value: parameter value + 4FH 4BH
4.4.4 Write (W)
Instruction format: 57H + parameter code + parameter value
Return value: 4FH 4BH
4.4.5 End instruction (O)
Instruction format: 4FH or addressing instruction which is not for local machine (bit 9 is ‘1’);
None return value.

The distributed control system is characterized of centralized administration and distributed control, which is
composed of Anthone intelligent instrument and superior computer. Control and data collection are done by
inferior instrument. The superior computer performs real-time supervisory control of whole process, records
and prints the history data. The fault of the superior computer does not affect the inferior instrument and
there is no fault diffusion between inferior instruments for the distributed control. Therefore, it reduces the
probability of system crash caused by local faults. Now the price of PC is very cheap and there is almost no
limit of memory capacity, so it has good cost performance.
Anthone DCS adopts RS485 communication rules when there are multi-set of instruments communicating
and the max. Communication distance is 1km. One communication line is allowed to connect with 128 sets
of Anthone serial intelligent instruments at most, and the system structure is very simple and convenient.
