1. Overview
1.1 T-PSV Overview
The T-series PLC DDE Server (hereafter called T-PSV) is an application software that runs on
Windows 98/Me/NT4.0/2000. The T-PSV works to collect data from T-series PLCs connected by
Ethernet and/or serial communication line, and to exchange the data with other Windows
application, such as Excel, using DDE (Dynamic Data Exchange). Data writing into the PLC is
also possible.
You can access any register/device data in the PLCs connected on Ethernet or serial line, and
can use these data on Windows application without need of developing the communication
program.
Configuration file for T-PSV:
This file specifies the PLC communication method, data sampling timing, Tag name
designation, etc. This file is CSV format which can be edited by Excel, etc.
DDE client application (Excel, Visual Basic, etc.):
The PLC's data can be displayed on Excel spreadsheet by designating the Tag name with
the DDE expression. Data writing into the PLC is also possible by using VBA.
T-PSV program:
The T-PSV is a program to gather the PLC's data based on the configuration file. When a
DDE client application requests the data, the T-PSV sends the data to the client application.
After that, the T-PSV sends the data when the data is changed.

1. Overview
1.2 System configuration
The T-PSV supports one Ethernet connection and one Serial connection at the same time.
On the Ethernet connection, up to 64 PLCs can be connected.
On the other hand, the Serial connection has three types of connection systems, RS485
computer link connection, programmer port connection, and TOSLINE-S20 connection. Either
one connection system can be selected among these three types.
(1) Ethernet connection
The Ethernet connection is available with T2N, T3H, S2T, S2 and S3. These PLCs can
have an Ethernet interface.
Up to 64 PLCs can be connected to the T-PSV. The transmission speed is 10Mbps. In this
configuration, personal computer's Ethernet port is used.
(2) RS485 Computer link connection
The RS485 computer link connection is available with T1S, T2E, T2N, T3, T3H, S2T, S2
and S3. These PLCs have an RS485 computer link port on the CPU module.
Up to 32 PLCs can be connected to the T-PSV. The transmission speed is up to 19.2kbps.
In this configuration, personal computer's Serial port is used. The RS232C/RS485 converter
(ADP-6237B) is used to convert to RS485.
Note) T1S means T1-16S and T1-40S which has the RS485 communication port.

(3) Programmer port connection
The programmer port connection is available with T1, T1S, T2E, T2N, T3, T3H, and S2T.
The interface of the PLC's programmer port is RS232C.
Only one PLC can be connected to the T-PSV. The transmission speed is fixed at 9.6kbps.
In this configuration, personal computer's Serial port is used.
(4) TOSLINE-S20 connection
The TOSLINE-S20 connection is available with T2E, T2N, T3, T3H and S2T. These PLCs
support TOSLINE-S20 connection.
Up to 64 PLCs can be connected to the T-PSV via TOSLINE-S20. The transmission speed
is fixed at 9.6kbps. In this configuration, personal computer's Serial port is used to connect
with the loader port of the TOSLINE-S20 station.
Note) TOSLINE-S20 is a Toshiba's high-speed control data network. Three types of
network configuration are available, co-axial bus, optical bus, and optical loop. The
transmission speed is 2Mbps. For details of the TOSLINE-S20, refer to the separate
TOSLINE-S20 manual.
