NAM IL S-202 Temp communication driver

NAM IL S-202 Temp communication driver is the driver to communicate with temperature controller of NAM IL Engineering in Korea.

1. Read Settings

<Figure 1> is read setting example of NAM IL S-202 Temp communication driver.

<Figure 1>  Read setting example of NAM IL S-202 Temp communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.

NAM IL S-202 Temp communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – 0 ~ 255 station number of S-202 controller.

2) Read command – command = R, G.

 G or S : read of setting value,

R, ... : read of current value. 

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. ( refer to <Table 1 >, <Table 2> )

Read schedule example)

READ,     1,    R,     0,    0,   1,

READ,     1,    G,     0,   10,   1,

<Table 1>, <Table 2> are data saving address contents of R, G read command

If you click the icon  in protocol option part at <Figure 1>, you can see the dialog box such as <Figure 2>. you can also set read schedule by using this part. 

<Figure 2> Example of NAM IL S-202 Temp communication driver’s Option dialog box

You can set read schedule by using , , button and listbox of <Figure 2>.

<Figure 3> Example of NAM IL S-202 Temp communication driver’s read schedule Add/Edit dialog box

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.

2. Write settings

You can set NAM IL S-202 Temp controller 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 of S-202 controller.

3)  ADDRESS          selection of setting value.

0 = setting of fan On temperature,

1 = setting of fan Off temperature,

2 = setting of warning temperature,

3 = setting of trip temperature. 

4)  Extra1                  writing command = S or space, ...

5) Extra2                   don't care.

Write example 1)

PORT:0,  station:1, ADDRESS:0000, Extra1: S,  Extra2 : 0

The setting parameter shown above is fan On temperature setting example of station 1 NAM IL S-202 Temp controller.

Write example 2)

PORT:0,  station:1, ADDRESS:0001, Extra1: S,  Extra2 : 0

The setting parameter shown above is fan Off temperature setting example of station 1 NAM IL S-202 Temp controller.

Write example 3)

PORT:0,  station:1, ADDRESS:0002, Extra1: S,  Extra2 : 0

The setting parameter shown above is warning temperature setting example of station 1 NAM IL S-202 Temp controller.

Write example 4)

PORT:0,  station:1, ADDRESS:0003, Extra1: S,  Extra2 : 0

The setting parameter shown above is trip temperature setting example of station 1 NAM IL S-202 Temp controller.

3. Connection of communication cable and main power

Connection of communication cable and main power are as follows:

Connection of communication cable

Please connect RS-485 communication cable to 12( + ), 13( - ) connector of S-202 controller such as <Figure 4>.
