GMPC II communication driver for GIMAC-IV

GMPC II communication driver is the driver to communicate with power meter GIMAC/GIMACII/GIMACIII/GIMAC-IV model of LSIS Co., Ltd.  in Korea.

GIMAC-IV model communicate with GMPC controller( GMPC I, GMPC II, GMPC III, GMPC V, ... ) and computer read and write GMPC's data.

1. Read settings

<Figure 1> is read setting example of GMPC II communication driver for GIMAC-IV model. 

<Figure 1>  Read setting example of GMPC II communication driver for GIMAC-IV model

Device part of  <Figure 1> input Com Port(COM1 or TCP/IP, UDP/IP, etc), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively according to setting of GMPC.

Baud rate, parity bit, data bit, stop bit can set by using switch of rear or front panel(GMPC controller).

GMPC II communication driver read schedule for GIMAC-IV

Read schedule setting parameters are as follows:

1) STATION – GIMAC-IV controller station number = 0 ~ 255.

2) Controller Model – Model = GIMAC4(when using GIMAC-IV model).

3) Read data type – Data type = 0, 1, 2, 3.... ( Cmd - 10h, refer to reference manual of GIMAC IV )

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

5) Read Size – Read size.  Fixed according to read data type. ( Refer to <Table 1>, <Table 2> )

6) Sub1 command - Input Sub1 command according to controller model.

7) Sub2 command - Input Sub 2 command according to controller model.

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

2. Writing settings

You can write GIMAC-IV equipment's setting value by using write settings. 

Digital Write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             GIMAC-IV controller station number = 0 ~ 255.

3)  ADDRESS          Setting data type(hex-decimal unit) number of Sub2, refer to <Table 3>.

4)  Extra1                   Model name = GIMAC4. ( GIMAC-IV model )

5)  Extra2                   Load control, Reset or Clear setting.

 0 – Load control,

1 – Reset or Clear command.

Note) Digital write for GIMAC-IV can control when the equipment's setting is 'remote'.

Write example 1)

PORT : 0  Station : 1,  ADDRESS : 0001,  EXTRA1 : GIMAC4,  EXTRA2 : 0

The setting parameter shown above is CB ON control example for 1 controller station GIMAC IV.

CB ON write command can control when the controller's setting is 'remote'.

Write example 2)

PORT : 0  Station : 1,  ADDRESS : 0002,  EXTRA1 : GIMAC4,  EXTRA2 : 0

The setting parameter shown above is CB OFF control example for 1 controller station GIMAC IV.

CB OFF write command can control when the controller's setting is 'remote'.

Write example 3)

PORT : 0  Station : 1,  ADDRESS : 0010,  EXTRA1 : GIMAC4,  EXTRA2 : 0

The setting parameter shown above is DO 1 On control example for 1 controller station GIMAC IV.

DO 1 On write command can control when the controller's setting is 'remote' and current status is 'Off'.

Write example 4)

PORT : 0  Station : 1,  ADDRESS : 0018,  EXTRA1 : GIMAC4,  EXTRA2 : 0

The setting parameter shown above is DO 1 Off control example for 1 controller station GIMAC IV.

DO 1 Off write command can control when the controller's setting is 'remote' and current status is 'On'. 

Write example 5)

PORT : 0  Station : 1,  ADDRESS : 0000,  EXTRA1 : GIMAC4,  EXTRA2 : 1

The setting parameter shown above is reset of Vo MAX value example for 1 controller station GIMAC IV.

Vo MAX value reset command can control when the controller's setting is 'remote'. 

Write example 6)

PORT : 0  Station : 1,  ADDRESS : 0010,  EXTRA1 : GIMAC4,  EXTRA2 : 1

The setting parameter shown above is a example of clear DO 6 On count.

Clear DO 6 On count command can control when the controller's setting is 'remote'. 

Analog Write

GMPC II communication driver for GIMAC-IV model don't support analog write.

3. Connection of main power and communication cable

 Connection of main power and communication cable are as follows.

Connection of main power

Please connect main power( 110 AC, etc ) to N, P connector at GIMAC-IV controller's rear panel such as <Figure 4>.

<Figure 5> is appearance of  GIMAC-IV controller.

<Figure 4> Connection example of main power and communication cable to GIMAC-IV controller

<Figure 5> Appearance of  GIMAC-IV controller

Note) GIMAC-IV Password input method : you can input 'password' by using 'UP' and 'Down' button of frong panel. ( Inital(default) Password : 0000 )

Connection of I-NET communication cable

Please connect I-NET RS-485 communication cable to Rx0,  Rx1, Tx0 , Tx1 connector such as <Figure 4>.

Note) When you connect GIMAC-IV and GMPC, you have to connect Rx = Tx, Tx = Rx respectively. ( I-NET cable = offered by LSIS Co., Ltd. when you buying GMPC or GIMAC-IV)

4. Setting of GMPC V

Connection of GMPC V almost equal with GMPC III. So you can refer to connection of GMPC III part.

<Figure 6> is apperance of GMPC V controller.

Note) Password input method : you can input 'password' by using 4 button of frong panel. ( Inital(default) Password : press 'FUNCTION', 'SELECT', 'UP', 'ENTER' button 2 times by turns )

Setting of GMPC V)

1. Time & Date   :  Date and Time setting of GMPC V.

2. Model   :  Model, protocol and communication method of  GMPC V.

Model | Protocol  : select GMP(I-NET protocol of GMPC) or MODBUS protocol,

Model | Media   : select communication media of GMPC V.

Model | Main Port :  select Primary(P) or Secondary(S).

3. Serial   :  select Com1 or Com2 port of GMPC V.

4. Network(This)  : select LAN1, LAN2 Ethernet port.

Network(This) | Ethernet Port  : select primary ethernet port of GMPC V.

Network(This) | IP_0  :  input IP Address of Primary Ethernet,

Network(This) | Port_0 No_0  :  input Port number of Primary Ethernet,

Network(This) | Netmask_0  :  input Subnet mask of Primary Ethernet,

Network(This) | Gateway_0  :  input Gateway IP Address of Primary Ethernet,

Network(This) | Host_IP0   :  input Host(PC, etc) IP Address of Primary Ethernet.

After setting GMPC V controller, save the setting by using 'ENTER' button.

Also, you have to reset(power off and power on) in order to apply the setting value. (don't reset, GMPC V use the old setting value)

Note) When you using the 'Ethernet' communication, you have to set Host(PC, etc) IP address at GMPC V controller.

Also if you don't use gateway at network, please set 'Gateway' IP address to '0.0.0.0'.

Note) You must input power for the first time of GIMAC-IV, etc, and input power GMPC V.

If you input power GMPC V the first and input GIMAC-IV, etc, GMPC V can't find connected equipment. So it may not be able to communicate with connected equipment.
