ShinPoong MUX-VWP is MUX controller manufactured by SHINPOONG Consultant, in Korea.

1. Read settings

<Figure 1> Read setting example of ShinPoong MUX communication driver

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

Set the TxRTS, RxECHO and etc at DEVICE setting part, because ShinPoong MUX controller only uses the 485 communication.

Also, you can set the read Delay time as min unit, therefore if protocol option is 60, it reads the whole, once every 60min(1 hour).

ShinPoong MUX-VWP protocol's READ schedule

Read schedule setting parameters are as follows : 

1) STATION - STATION number of ShinPoong MUX-VWP controller. (Decide according to ROM type)

2) FUNCTION - Don't care.

3) Read Start Address - Channel value

4) Save Start Address for Communication Server - ScanBuf position where read value is saved.

5) Read Size - Fixed to 1

READ schedule example)

FLOAT,   11,   0,    1,   0,  1,

FLOAT,   11,   0,    2,   1,  1,

FLOAT,   11,   0,    3,   2,  1,

FLOAT,   11,   0,    4,   3,  1,

FLOAT,   11,   0,    5,   4,  1,

FLOAT,   11,   0,    6,   5,  1,

FLOAT,   11,   0,    7,   6,  1,

FLOAT,   11,   0,    8,   7,  1,

Reference)

ShinPoong MUX controller's communication speed is slow a little, so, reading the only needed channel is encouraged.

Also, there is some case that sometimes abnormal value is entered at channel where sensor isn't installed. If you install the sensor, problem is solved.

Information memory structure)

Each information is taken to WORD memory. if you use this, you can use as tag at LocalMain program.

2. Writing settings

Output can't be used.
