Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to PLC.
Read schedule of TOSHIBA EX100 PLC is as follows.
| READ | Station | Memory Type | Read Start Address | Save Start Address for Communication Server | Read Size (1 ~ 32) |
| READ, | 0, | DW, | 0, | 0, | 32, |
| READ, | 0, | RW, | 0, | 32, | 32, |
| READ, | 0, | XW, | 0, | 50, | 2, |
| READ, | 0, | YW, | 0, | 60, | 2, |
| <Table 1> Read schedule of TOSHIBA EX100 protocol | |||||
1) Station : RTU station.
2) Memory Type : Enter the PLC memory – DW, D, RW, R(bit unit), XW, X(bit unit), YW, Y(bit unit), ZW, Z(bit unit), TW, T, CW, C, ER, ST, IR, SR, TR, etc.
3) Read Start Address : Start address to read in memory.
4) Save Start Address for Communication Server : Saving start address of Communication Server.
5) Read Size : The number of items to read at a time. Number of Bit or Word between 1 and 32.
You have to set Communication Switch of communication card as 'LINK' mode to communicate with TOSHIBA EX100 PLC and communication program.
(PROGRAM mode is Programer mode)
Also, if you set Station Number Selector between 0 and F, you can set station number between 0 and 15. And you can control Com Baud and Parity by using DIP switch.

Digital Write
Digital write setting parameters are as follows:
PORT Connected PORT number 0 ~ 255
STATION Station 0 ~ 15
ADDRESS Output address 0000 ~
EXTRA1 Memory area DB, TB, CB, X, Y, Z, R – Output as bit unit.
DB, TB, CB memory area is written by combining designated bit by reading DW, TW, CW memory area.
D, DW, XW, YW, ZW, RW, C, CW, T, TW – Change Word value 0 or 1.
EXTRA2 Don't care
Write example 1)
Port : 0, Station : 0, ADDRESS : 0002, Extra1 : R
The setting parameter shown above is example of changing(ON/OFF) 3rd bit value connected with R memory and EX100 PLC.
Analog Write
Analog write setting parameters are as follows:
PORT Connected PORT number 0 ~ 255
STATION Station of RTU 0 ~ 15
ADDRESS Output address 0000 ~
EXTRA1 Output type D, DW, XW, YW, ZW, RW, C, CW, T, TW – Write Word value.
DB, TB, CB, X, Y, R – Write only 0 and 1 value(bit unit).
DB, TB, CB memory area is written as 0 or 1 by combining designated bit by reading DW, TW, CW memory area.
EC – EX Control output method. (Refer to <Table 12> for output method)
EXTRA2 Don't care
Write example 1)
Port : 0, Station : 0, ADDRESS : 0001, Extra1 : DW
The setting parameter shown above is example of changing 2nd area value connected with EX100 PLC and D memory.
Write example 2)
Port : 0, Station : 0, ADDRESS : 0000, Extra1 : EC
The setting parameter shown above is of RUNNING(refer to <Table 12>) EX100 PLC by writing value as 2.
