GLOFA GM Loader communication driver is the driver to communicate with GLOFA GM series PLC of Loader port of LSIS Co., Ltd. in Korea.
In order to communicate with GLOFA PLC's Loader port, you have to connect RS-232C communication cable.
<Figure 1> is read setting example of GLOFA GM Loader communication driver.

Device part of <Figure 1> input Com Port(COM1), Baud Rate(38400), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively.
Note) GLOFA GM Loader port's Baud rate, Parity Bit, Data Bit, Stop Bit are fixed to 38400, 0, 8, 1.
GLOFA GM Loader communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – Don't care. ( Fixed to 0 )
2) Read memory type – Memory type.( Refer to <Table 1> )
IW , ID, IX : Word, Dword, 10 Bit unit data read of 'I'(input) memory area,
QW, QD, QX : Word, Dword, 10 Bit unit data read of 'Q'(output) memory area,
MW, MD, MF, MX : Word, Dword, Float, 10 Bit unit data read of 'M'(internal) memory area.
3) Read start address – Read start address in memory.( I, Q memory = fixed to 0 )
4) Save Start Address for Communication Server – saveing start address of Communication Server.
5) Read Size – Word/Dword/Float unit read size.
IW, QW, MW memory type = Word unit read size,
ID, QD, MD memory type = Dword unit read size,
MF memory type = Float(Dword) unit read size,
IX, QX, MX memory type = 10 Bit unit read size. ( 1 = 10 bit )
6) Base number – 0 ~ 127 Base number when I, Q memory.
7) Slot number – 0 ~ 15 Slot number when I, Q memory.

You can set Glofa PLC by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care. ( Fixed to 0 )
3) ADDRESS Decimal unit write address in memory.
M memory type : decimal unit write address,
Q memory type : upper 2 ~ 6 digit = Slot number, lower 2 digit = Point number.
4) Extra1 Write memory type = M, Q, etc.
5) Extra2 Base number when Q memory type.(decimal unit)
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0011, EXTRA1 : M, EXTRA2 :
The setting parameter shown above is a control(On/Off) example for %MX0011.
Write example 2)
PORT : 0 Station : 0, ADDRESS : 0102, EXTRA1 : Q, EXTRA2 : 0
The setting parameter shown above is a control(On/Off) example for 0 Base, 1 Slot, 2(3rd) point number of Q memory type.( %QX0.1.2 )
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care. ( Fixed to 0 )
3) ADDRESS Decimal unit write address in memory.
M memory type : decimal unit write address,
Q memory type : upper 2 ~ 6 digit = Slot number, lower 2 digit = Point number.
4) Extra1 Write memory type.
MB, QB : Byte unit write,
MW, QW, M, Q : Word unit write,
MD, QD : Double Word unit write,
MF : Float unit write.
5) Extra2 Base number when Q memory type.(decimal unit)
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0100, EXTRA1 : QW, EXTRA2 : 0
