Device part of <Figure 1> input Device type(COM1), Com Baud(9600), Parity Bit(0), Data Bit(8), Stop Bit(1), respectively, according to controller settings.
In case of directly connecting control panel to control unit, set '0' at option part of communication setting. And in case of doing not direct connection, enter as '1'.
RKC SR Mini HG communication driver's read schedule
Read schedule setting parameters are as follows:
1) STATION : STATION number which is set at controller(0000~9999).
A number in the thousands, a number in the hundreds : Panel number.
A number in the tens, a number in the one digit : Unit number.
2) Read Type : Input memory type. Refer to <Table 1> or SR Mini HG system manual.
3) Read Start Address : Don't care.
4) Save Start Address for Communication Server : Readed data saving start address of communication server.
5) Read Size : Read size. Fixed according to memory type.
Read schedule example)
| READ | STATION | Read Type | Read Start Address | Memory Save Address | Read Size (Fixed to 1) |
| READ, | 1, | M1 | 0, | 0, | 1 |
| READ, | 1, | AA | 0, | 10, | 1 |
| READ, | 1, | AB | 0, | 20, | 1 |
| FLOAT, | 1, | S1, | 0, | 0, | 1, |
| FLOAT, | 1, | P1, | 0, | 10, | 1, |
SR Mini HG system controller's each memory area size is fixed according to system settings.

| B1 | Burnout | |
| ER | Error Code | 0 ~ 255, Read Only |
| SR | RUN/STOP Function | 0:OFF, 1:ON, Read/Write |
| S1 | Set value(SV) | SV Setting Value, Read/Write |
| A1, A2 | Alarm 1, 2 Setting | Read/Write |
| P1 | Heat-side proportional band | |
| I1 | Integral time | 1~3600 sec(0:PD control), Read/Write |
| D1 | Derivative time | 1~3600 sec(0:PI control), Read/Write |
| T0 | Heat-side proportioning cycle | 1~100 sec, Read/Write |
| P2 | Cool-side proportioning band | 1~1000% sec, Read/Write |
| V1 | Deadband | Temp Input :-10~10, Read/Write |

Write to direct address of controller, regardless of SCAN File.
Digital Write
Digital write setting parameters are as follows :
1) PORT Connected PORT number(0 ~ 255)
2) Station Station number 0000 ~ 9999.
A number in the thousands, a number in the hundreds : Panel number.
A number in the tens, a number in the one digit : Unit number.
3) ADDRESS Channel number 1 ~
4) Extra1 Memory area Refer to <Table 1> or SR Mini HG system manual.
5) Extra2 Channel classification Enter 100 to memory(SR, IN memory etc) without channel classification, enter 1 in case of digital output memory(Q4 etc).
Write example 1)
Port:0, Station:1, Address:0000, Extra1:SR, Extra2:100
The setting parameter shown above is example for RUN/STOP the RKC SR Mini HG controller.
Write example 2)
Port:0, Station:1, Address:0001, Extra1:J1, Extra2:0
The setting parameter shown above is example for changing Auto/Manual transfer status of 1 channel of RKC SR Mini HG controller.
Analog Write
Analog write setting parameters are as follows :
1) PORT Connected PORT number(0 ~ 255)
2) Station Station number 0000 ~ 9999.
A number in the thousands, a number in the hundreds : Panel number.
A number in the tens, a number in the one digit : Unit number.
3) ADDRESS Channel number 1 ~
4) Extra1 Memory area Refer to <Table 2> or SR Mini HG system manual.
5) Extra2 Channel, all and the number of digits of decimal point
3 digits number : 1 = Memory without channel classification(SR, IN etc), 0 = Channel classification memory(MI, S1 etc).
2 digits number : 1 = Memory which outputs as 1 digit(AA, AB etc), 0 = Memory which outputs as 6 digits(S1, P1, P2 etc).
1 digit number : 0 = Memory without decimal point(AA, AB etc), 1 = Memory for 1 digit of decimal point(ON, V1 etc), 2 = Memory for 2 digit of decimal point(PB etc), 3 = Memory for 3 digit of decimal point(KG etc).
