MYPRO CPIII communication driver

MYPRO CPIII( and MDC ) communication driver is the driver to communicate with screw compressor of  MAYEKAWA Total System21 in Japan.

Note) Station number of MYPRO CPIII/MDC controller can use 1 ~ 31. ( don't use 0 station number )

1. Read Settings

<Figure 1> is read setting example of MYPRO CPIII communication driver.

<Figure 1>  Read setting example of MYPRO CPIII communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(2), Data Bit(7), Stop Bit(1) respectively, according to setting of controller.

Note) Baud rate, parity bit, data bit, stop bit of MYPRO CPIII/MDC can set by using front panel's setting button.

MYPRO CPIII communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – 1 ~ 31 station number. ( don't use 0 station number )

2) Read command – don't care.

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 > )

Read schedule example)

READ,     1,     0,     0,    0,   1, 

READ,     2,     0,     0,   50,   1, 

<Table 1> is data saving address and contents of MYPRO CPIII communication driver.

<Table 2> is data value and meanings for operation mode. <Table 3> is contacts and contents for each bit.

<Table 4> is name and alarm contents for each bit.

MYPRO CPIII communication driver store the same data in WORD, DWORD, FLOAT, STRING memory, but the data format are different.

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 MYPRO CPIII communication driver’s Option dialog box

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

<Figure 3> Example of MYPRO CPIII 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 MYPRO CPIII/MDC 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             1 ~ 31 station number. ( don't use 0 station number )

3)  ADDRESS          data saving start address when READ write command. ( refer to <Table 1> )

4)  Extra1                  writing command = READ, SET1 ~ SET6, CON1 ~ CON3. ( refer to <Table 5> )

5) Extra2                   don't care.

<Table 5> is write command and contents of MYPRO CPIII communication driver.

Write example 1)

PORT:0,  station:1, ADDRESS:0100, Extra1: READ,  Extra2 : 0

The setting parameter shown above is read request setting example of station 1 MYPRO CPIII controller.

After reading, the readed data save at 100 ~ 134 address WORD, DWORD, FLOAT memory such as <Table 1>.

Write example 2)

PORT:0,  station:1, ADDRESS:0000, Extra1: SET1,  Extra2 : 0

The setting parameter shown above is setting example for setting value 1.

Write example 3)

PORT:0,  station:2, ADDRESS:0000, Extra1: SET6,  Extra2 : 0

The setting parameter shown above is setting example for setting value 6.

Write example 4)

PORT:0,  station:1, ADDRESS:0000, Extra1: CON1,  Extra2 : 0

The setting parameter shown above is 100% operation command control( On or Off ) example of station 1 MYPRO CPIII controller.

Write example 5)

PORT:0,  station:2, ADDRESS:0000, Extra1: CON1,  Extra2 : 0

The setting parameter shown above is 100% operation command control( On or Off ) example of station 2 MYPRO CPIII controller.

Write example 6)

PORT:0,  station:1, ADDRESS:0000, Extra1: CON3,  Extra2 : 0

The setting parameter shown above is run command for freezer 1 unit control( On or Off ) example of station 1 MYPRO CPIII controller.

3. Connection of communication cable

Please connect RS-485 communication cable to A( + ), B( - ) connector of MYPRO CPIII/MDC controller such as <Figure 4>.
