Device part of <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
Note) Baud rate, parity bit, data bit, stop bit of Mini-Convectron Module can set by using SB, SPN, SPO, SPE, RST write command.
Mini-Convectron Module communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 0 ~ 255 station number. DIP switch address(0 ~ 15) + address Offset by SA write command.
2) Read command – command = RD, RH, RL, VER, RU. ( refer to <Table 1> )
3) Read start address – don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1.

FLOAT, 10, RD, 0, 0, 1,
FLOAT, 10, RH, 0, 1, 1,
FLOAT, 10, RL, 0, 2, 1,
READ, 10, RU, 0, 3, 1,
<Table 1> is read command and contents of Mini-Convectron Module communication driver.
| Read command | Contents | Saving data |
| RD | Read Pressure | pressure value(FLOAT data) |
| RH | Read Set Point 2 | Set Point 2 value(FLOAT data) |
| RL | Read Set Point 1 | Set Point 1 value(FLOAT data) |
| VER | Read Firmware Version | version of firmware (also, save STRING memory ) |
| RU | Read Unit of Measure | uint of measure(also, save STRING memory ) 1 = MBAR, 2 = PASCAL, 4 = TORR, 128 = other |

Mini-Convectron Module communication driver store the same data in WORD, DWORD, FLOAT, STRING( only VER, RU command ) memory, but the data format are different.
If you click the icon 
in protocol option part at
<Figure 1>, you
can see the dialogue box such as <Figure 2>. you can also set read schedule by
using this part.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can set Mini-Convectron Module by using 'write settings'.
Digital Write
Digital write and analog write have the same setting parameters except output value.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION 0 ~ 255 station number. DIP switch address(0 ~ 15) + address Offset by SA write command.
3) ADDRESS writing status saving memory address when TS, TZ command.
4) Extra1 write command = SA, TS, TZ, SH, SL, FAC, SB, SPN, SPO, SPE, SF, RST, SU. ( refer to <Table 2>, <Table 3> )
5) Extra2 don't care.
