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 PLC station number = 0 ~ 31.
3) ADDRESS Write address in memory.
MX memory type : decimal unit write address,
MW memory type : upper 2 ~ 6 digit = decimal unit Word address, lower 1 digit = 0 ~ F bit position,
QX memory type : upper 2 ~ 6 digit = Slot number, lower 2 digit = Point number.
4) Extra1 Write memory type = MX, MW, QX, etc.
5) Extra2 Base number when Q memory type or multi bit write setting,
QX memory type : decimal unit base number,
other memory type : multi digital(bit) write setting,
1 = save multi digital write data, ( Extra1 = don't care when this case )
2 = multi digital write execute for currently saved data, ( multi digital write from input address by saved data count )
3 = delete all saved multi digital write data, ( Extra1 = don't care when this case )
0 or etc = normal digital(bit) write.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0000, EXTRA1 : MX, EXTRA2 :
The setting parameter shown above is a control(On/Off) example for %MX0000.
Write example 2)

The setting parameter shown above is a control(On/Off) example for %MX0050.
Write example 3)
PORT : 0 Station : 0, ADDRESS : 11215, EXTRA1 : MX, EXTRA2 :
The setting parameter shown above is a control(On/Off) example for%MX11215(%MW0700.F).
Write example 4)
PORT : 0 Station : 0, ADDRESS : 700F, EXTRA1 : MW, EXTRA2 :
The setting parameter shown above is a control(On/Off) example for %MW0700.F( MX = 700 * 16 + 15 = 11215).
Write example 5)
PORT : 0 Station : 0, ADDRESS : 0203, EXTRA1 : QX, EXTRA2 : 0
The setting parameter shown above is a control(On/Off) example for 0 Base, 2 Slot, 3 point number of Q memory type.( %QX0.2.3 )
Script example for multi digital write)
$DO_0000.Extra2 = 3; //delete saved multi digital write data
@SetTagValue("DO_0000", 0);
$DO_0000.Extra2 = 1; // setting of save multi digital write data
for(i = 0; i < 16; i = i + 1) {
@sprintf($DO_0000.Extra1, "%03d", i); // input arbitraty value to Extra1, so don't ignore the equal data
@SetTagValue("DO_0000", 1); // save multi digital write data, output value = 1(ON)
}
@sprintf($DO_0000.Extra1, "MX"); // don't care memory type, MX, MW, ...

$AO_0000.Extra2 = 1; // setting of save multi analog write data
for(i = 0; i < 25; i = i + 1) {
@sprintf($AO_0000.Extra1, "%03d", i); // input arbitraty value to Extra1, so don't ignore the equal data
@SetTagValue("AO_0000", 5000); // save multi analog write data, output value = 5000
}
@sprintf($AO_0000.Extra1, "MW"); // don't care memory type, MW, MD, MF, ...
$AO_0000.Extra2 = 2; // setting of multi analog write
@SetTagValue("AO_0000", 1); // execute multi analog write from saved data to internal memory, saved data count = 25, write memory type = MW
Please connect full RS-232C Serial communication cable for GLOFA PLC such as <Figure 2>.

| <Figure 2> RS-232C communication cable for Glofa CNET communication driver |
1) Check 'Mode switch' of CNET communication module. You have to set 'dedicated communication mode' of Mode switch. ( can't communicate when 'User define Mode' or 'Test Mode')
Please refer to reference manual of GLOFA PLC for more information.
2) Please check the connection of communication cable. It can't communicate when you using 'communication cable for Ladder'.
3) Check station number of PLC.
4) Check baud rate of PLC and driver setting for Glofa CNET communication driver.
Baud rate can set by using 'Frame Editor'.
