DAE GIL EL-300P Load communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – Don't care.
2) Read Command – Command = L_STS, MODEL, LED, SET, MEA, RES, COUNT ( Refer to <Table 1> )
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.

READ, 0, SET, 0, 0, 1,
READ, 0, MEA, 0, 20, 1,
READ, 0, RES, 0, 30, 1,

<Table 1> is store values and contents of DAE GIL EL-300P Load communication driver.
| Read command | Contents | Store Values |
Range ( Decimal ) |
| L_STS | Read of load status | Start Addr + 0 =Local/Remote status |
0 = Local, 1 = Remote |
| MODEL | Read of load model | Start Addr + 0 = Watt Limit, Start Addr + 1 = Volt Limit, Start Addr + 2 = Current Limit |
65 ( 210W ) ~ 80 ( 15750W ), 65 ( 63.00V ) ~ 68 ( 210.0V ), 65 ( 40.00A ) ~ 72 ( 840.0A ) |
| LED | Read of LED status | Start Addr + 0 = LED Status |
Refer to <Table 2> |
| SET | Read of setting status | Start Addr + 0 ~ 17 |
Refer to <Table 3> |
| MEA | Read of measurement status | Start Addr + 0 = Voltage, Start Addr + 1 = Current, Start Addr + 2 = OTP |
voltage, current = read value / 100( floating point data ) OTP : 0 = normal, 1 = high temperature |
| RES | Read of resistance | Start Addr + 0 = Resistance value |
Floating point value ( Refer to FLOAT memory ) |
| COUNT | Read of Count value | Start Addr + 0 = Count value |

DAE GIL EL-300P Load communication driver store the same data in WORD, DWORD, FLOAT memory, but the data formats are different.
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>.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can write the setting value by using write settings.
Bit Write
Bit write and word write have the same setting parameters except output value. ( 0 , 1 )
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Decimal unit saving start address for read command(L_STS, MODEL, LED, SET, MEA, RES, COUNT).
Write command : Don't care.
4) Extra1 Read/Write command.
Read command = L_STS, MODEL, LED, SET, MEA, RES, COUNT. ( Refer to <Table 1> )
Write command = Refer to <Table 4>.
5) Extra2 Don't care.
