TOSHIBA T2/T3 Ethernet/Serial Communication Driver

 

TOSHIBA T2/T3 Ethernet/Serial is driver to communicate with T2/T3 PLC of Toshiba Co., in Japan.

T2, T3/T3H, etc are wide use PLC of TOSHIBA Co. in Japan.

TOSHIBA T2/T3 Ethernet/Serial communication driver can Serial communication such as Ethernet and RS-232C.

                  Ethernet : Connect to 10Base5, 10Base2 ( LAN ) terminal of Ethernet communication card such as EN311, etc.

                  RS-232C Serial  : Connect to RS-232C terminal of Serial communication card.

 

Reference) In case of ethernet communication( UDP/IP ) by using TOSHIBA T2/T3 Ethernet/Serial driver, it is possible to access to one PLC to one port.

 

But, if you control read speed( Set read cycle as 500 mSec ) and computer is different, it is possible to access 2 ~ 3 computers( Only one access to one computer ).

(It can be different according to CPU type)

 

Importance) Communication with ethernet communication card needs communication program( PLC_SCAN.exe ) more than 8.3.6 or 8.4.1 version.

 

1. Read settings

 

<Figure 1> is read setting example of TOSHIBA T2/T3 Ethernet/Serial driver.
<Figure 1> Read setting example of TOSHIBA T2/T3 Ethernet/Serial driver
 

In case of Ethernet communication by using TOSHIBA T2/T3 Ethernet/Serial driver DEVICE settings are entered as Device type(UDP/IP), IP address of PLC(192.168.1.106), service port number( 1024 : Refer to no.4 item ), respectively, according to setting of Ladder program such as no.4 item.

Also, in case of Serial communication by using TOSHIBA T2/T3 Ethernet/Serial driver DEVICE settings are entered as COM1, 9600,0,8,1, in order, according to setting of Serial communication card.

 

Importance) TOSHIBA T2/T3 Ethernet communication support UDP/IP only, currently, and it is possible to communicate when settings of IP and service port are entered at Ladder program.

 

TOSHIBA T2/T3 Ethernet/Serial communication driver's read schedule

Read schedule setting parameters are as follows:

1)      STATION – PLC Station number between 0 and 15. (Not use in case of UDP/IP communication)

2)      Read memory type – X, Y, L, W, F, R, S, C, T, D, etc. (Refer to <Table 1>)

3)      Read start address – Start address to read.

Always WORD unit address – Use same start address with WORD/DWORD/FLOAT.

4)      Save Start Address for Communication Server - Saving start address of Communication Server.

5)      Read Size - Number of WORD/DWORD/FLOAT to read.

(It is possible to read maximum 32 WORD, 16 DWORD/FLOAT data, at a time)

3. Basic power and communication cable connection

 

Basic power connection

Connect 100 or 220V AC power to power module of <Figure 4>. ( Select power type : 100V = Short, 220V = Open )

 

Ethernet module auxiliary power connection

Connect 12V DC power to Auxiliary power input section of Ethernet module such as <Figure 4>.

<Figure 4> Example of installing module of Ethernet ,etc to TOSHIBA T3 PLC

Ethernet communication cable connection

Connect Ethernet communication cable to ( EN311, etc ) 10Base5, 10Base2 ( LAN ) terminal of Ethernet module such as <Figure 4>.

 

4. Setting for IP and service port of Ethernet communication card

IP address, etc of Ethernet communication card is set by using 'T-PDS32 for Windows' Ladder program supported from TOSHIBA Co., as follows.

1) Make a new project or open existing project by executing T-PDS32 for Windows program.

2) Add the contents such as <Figure 5> to Ladder.

3) <Figure 5> is example of setting for UDP/IP communication by using 192.168.111.126 IP address and no.1024 service port.

4) –22336 = A8C0h and 32367 = 7E6Fh at <Figure 5>, these become 192(C0), 168(A8), 111(6F), 126(7E) by displaying as decimal, in Low Byte order.

5) This 192, 168, 111, 126 number is IP address. ( It is possible to write different IP address by modifying number )

6) Also, 1024 of '01024 MOV RW004' area is service port number. ( Refer to <Table 3> ~ <Table 5> )

 

Notice) In case of writing Ladder such as <Figure 5> and reclosing the PLC power, you have to make ON the R0501, R0502, R0503 each once to complete the setting for service port and IP address which you want.
