Glofa Ethernet communication driver is the driver to communicate with Glofa PLC of ethernet port of LSIS Co., Ltd. in Korea.
<Figure 1> is read setting example of Glofa Ethernet communication driver.

Device part of <Figure 1> input Device type(TCP/IP or UDP/IP), IP address of PLC(192.168.1.86), service port of TCP/IP(UDP/IP) protocol (fixed to 2004 for TCP, UDP = 2005 ),respectively, according to setting of PLC.
Also you can input enable of 'Error when PLC is slave' (0 : don't care, 1 : Error, default = 1), use of 'Bit Write word unit address for MW, QW memory type'(0 : don't use, BIT_WORD : use, default = 0), by using option part.
Note) Connectoin number of TCP/IP protocol and IP address of PLC, connection waiting time can set by using by using 'Frame Editor' of LSIS.
When the PLC status is 'slave' and lots of timeout occur, you set to 'Error when PLC is salve' mode = 0 (disable).
But when you using 'Line Duplex', you can set 'Error when PLC is salve' = 1( enable ). So you can transfer to 'Master' PLC'.
Glofa Ethernet 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.( QX, IX, MX = 10 x address )
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) Rack(Base) number – 0 ~ 127 Rack number when I, Q memory.
7) Slot number – 0 ~ 15 Slot number when I, Q memory.
Read schedule example)
READ, 0, QW, 0, 0, 4, 0, 1,
READ, 0, QX, 0, 10, 6, 0, 1,
READ, 0, IW, 0, 20, 4,
READ, 0, IX, 0, 30, 6,
READ, 0, MW, 0, 50, 100,
DWORD, 0, MW, 200, 150, 100,
Note) Rack and Slot number are card position of PLC. ( I, Q memory )

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.

You can set read schedule by using 
, 
, 
button and listbox
of <Figure 2>.
Also you can set enable of error when PLC is slave and use of bit write word unit address for MW, QW memory type at the part of ¡®Error when PLC is Slave', 'Use Bit Write Word Unit Address(MW, QW)' shown in <Figure 2>.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
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 Write address in memory.
Q, QX memory type : upper 2 digit = Slot number, lower 2 digit = Point number,
MW, QW memory type : upper 3 digit = decimal unit Word address, lower 1 digit = 0 ~ F bit position when you set 'use of bit write word unit address for MW, QW',
etc memory type : write address in memory type.
4) Extra1 Write memory type = Q, QX, MX, etc.
When you set 'use of bit write word unit address for MW, QW : QW, MW memory type.
5) Extra2 Base number when Q, QX memory type.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0110, EXTRA1 : QX, EXTRA2 : 0
The setting parameter shown above is a control(On/Off) example for 0 Base, 1 Slot, 10 point number of Q memory type.( %QX0.1.10 )
Write example 2)
PORT : 0 Station : 0, ADDRESS : 1207, EXTRA1 : MX, EXTRA2 : 0
The setting parameter shown above is a control(On/Off) example for %MX1207(%MW0075.7).
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 Bit, word, dword, float unit write address in memory.
Q, QX memory type : upper 2 digit = Slot number, lower 2 digit = Point number,
etc memory type : write address in memory type.
4) Extra1 Write memory type = Q, QX, M, MX, etc.
5) Extra2 Base number when Q, QX memory type.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0001, EXTRA1 : M, EXTRA2 :
The setting parameter shown above is word write example for 0001 word of M memory type.( %MW0001 )
