SABROE Protocol 0178-400 Communication Driver

SABROE Protocol 0178-400 Communication Driver is the driver to communicate with  Comressor/Chiller of Sabroe Refrigeration in Denmark.

Note) SABROE Protocol 0178-400 Communication Driver's help is written by Comressor equipment.

You can reference to SABROE Protocol 0178-400 manual for Chiller equipment's point address, ... etc.

1. Read settings

<Figure 1> is read setting example of SABROE Protocol 0178-400 communication driver.

<Figure 1>  Read setting example of SABROE Protocol 0178-400 communication driver

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

SABROE Protocol 0178-400 communication driver’s read schedule

Read schedule setting parameters are as follows:

1) STATION – 0 ~ 14 equipment address.

2) Equipment type – DATA or COP.

3) Read Start Address – point no. = 32 ~ 255. (Refer to <Table 1>, <Table 2>)

4) Save Start Address for Communication Server – Saving start address of Communication Server.

5) Read Size – Size = Fix to 1.

Read schedule example)

READ, 1, DATA, 32, 0, 1,
READ, 1, DATA, 33, 1, 1,
READ, 1, DATA, 34, 2, 1,
READ, 1, DATA, 35, 3, 1,
READ, 1, DATA, 36, 4, 1,
READ, 1, DATA, 37, 5, 1,

<Table 1> is a description of 'DATA' read command's point no. and stored values of SABROE Protocol 0178-400 communication driver.

<Table 2> is a description of 'COP' read command's point no. and stored values of SABROE Protocol 0178-400 communication driver.

SABROE Protocol 0178-400 communication driver store the same data in WORD, DWORD, FLOAT memory, but the data formats are different.

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

<Figure 2> Example of SABROE Protocol 0178-400 communication driver’s read schedule Add/Edit dialogue box

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

<Figure 3> Example of SABROE Protocol 0178-400 communication driver’s read schedule Add/Edit dialogue box

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

2. Write settings

You can write setting values of Comressor/Chiller equipment by using write commands.

Bit write

Bit write and word write have the same setting parameters except output value(0 or 1).

Word write

Word write setting parameters are as follows:

1) PORT : Port no. (0 ~ 255)

2) STATION : 0 ~ 14 equipment address.

3) ADDRESS : point no. 32 ~ 255. (Refer to <Table 3>)

4) EXTRA 1 : ANA = analog write point, NOR = normal write point.

5) EXTRA 2 : Don't care.

<Table 3> is a description of point no. and contents, EXTRA1, range for write of SABROE Protocol 0178-400 communication driver.

Write example 1)

PORT:0,  station:1, ADDRESS:0032, Extra1:NOR, Extra : 0

The setting parameter shown above is an example of word write for Start sequence no.(0 ~ 14) of SABROE Protocol 0178-400 connected with 0 port and 1 equipment address(station).

Write example 2)

PORT:0,  station:1, ADDRESS:0050, Extra1:ANA, Extra : 0

The setting parameter shown above is an example of word write for Setpoint 1, brine temperature of SABROE Protocol 0178-400 connected with 0 port and 1 equipment address(station).

(EXTRA1 : Write range = Real data x 10.0,    ex) write value = 275, then, Real data = 27.5)

Block write

SABROE Protocol 0178-400 communication driver don’t support ‘Block write’.
