Toshiba's V2000 Programmable controller is designed for the serious PLC user. V-Series S2E/S2T Small, Powerful Modular Style Programmable Controllers

Toshiba’s S2E/S2T controllers are small, modular type programmable controllers suitable for simple relay replacement all the way to complex control applications. The S2E/S2T are 3rd generation T2 Series CPUs used with V-
Series racks, I/O, and power supplies. The S2E/S2T provides a functional, economical, and compact solution to a wide range of applications in automotive, machine control, and process control systems.

High Speed Processing

The S2E/S2T controllers excel at applications where high speed processing is required.
Contact Instruction 0.11 µs0.09 µs
Coil Instruction: 0.22 µs0.18 µs
Transfer Instruction 0.65 µs0.54 µs
16-bit Addition 1.08 µs 0.90 µs

T-Series Compatible

The programming tool for the S2E/S2T is the T-PDS MS Windows based programming software.  Any T-Series program can be loaded and run
without any program conversion. Any HMI, OIS, or Scada software used with the T-Series is also compatible.

Comment Storage in CPU

The device/register tag and comment can be stored in the S2E/S2T CPU memory. Tags and comments can be viewed in the on-line mode without access to the original program (tags and comments are normally stored on the computer hard disk that created the program). Debugging, trouble shooting and editing is much simpler at the installation if tags and comments are viewable.

Built-in Serial Communications

The S2E/S2T have an RS485 serial communications port on the CPU module. One of two modes is selectable; computer link mode or free ASCII mode. In the computer link mode a higher level controller, MMI/OIS, SCADA  software can connect to the CPU. T-PDS programming software can also connect in this mode for remote programming. In the free ASCII mode the CPU can communicate with devices that have a simple ASCII protocol such as T1 PLCs, Toshiba ASDs, bar code readers, etc.

Large Program Memory.

Both S2E & S2T CPUs have 32k steps of program memory (64k step S2T version is also available). This allows program creation without any consideration for memory constraints. Non-volatile flash memory is used for permanent program storage. Important register values can also be stored in flash memory.

Debug Support Functions

The S2E/S2T offer many useful on-line debug  functions such as input force, coil force, data set, status latch & sample trace.

Process I/O

Fast 8 channel analog input modules and 4 channel analog output modules solve many difficult process applications. One analog output module has an output hold function for safety during a down condition.

Multiple Programming Languages

 Both LD (ladder diagram) and SFC (sequential function chart) programming are available. Up 11 lines of ladder can be included in each SFC action block. Using SFC makes programs easier to understand and it makes the system easier to troubleshoot.

System Configurations

The S2E/S2T configurations are available from a very simple 3 I/O slot system to a to a large local system with several networking options.

Basic System

The simplest configuration consists of a power supply, S2E/S2T CPU, and any combination of 3 I/O or network modules.
v2000 basic

Medium sized System:

A fully integrated system consists of a power supply, an S2T CPU, a computer module, and any combination of 6 I/O or network modules.
v2000 Intergrated

Fully Expanded System

A maximum system consists of a main rack and 3 expansion racks. Each rack can have up to 8 I/O modules. Expansion racks can also accept network modules. In addition to V-Series expansion racks, T2 Series expansion racks can also be connected to the main rack. A combination of V-Series and T2 Series expansion racks is possible.
♦ A power supply module is necessary in each rack.
♦ Expansion cables are available in the following lengths:  30 cm,  50 cm,  70 cm,  1.2 m  Max total length = 4.5 m

What makes a System?

A typical S2E/S2T system consists of a base rack with modules mounted on the rack. From left to right modules are: Expansion Interface, Power Supply, CPU, and I/O modules. If the rack supports the station bus, then a computer module or higher level network module can be mounted following the CPU module.

Ethernet is used as an open industrial networking standard. The GEN651 card allows the S2T to access other devices connected on an Ethernet network. Either 10 or 100 Mbps data rates can be selected. Cables, routers, switches, transceivers, converters, etc. are commonly available from 3rd party vendors.


FL-Net is a multi-vendor open network. Any equipment (PLC, NC, Robot Controller, etc.) that has an FL-Net certified communications module can communicate on FL-Net. FL-Net is a 10 Mbps deterministic Ethernet based network. Each station has a common memory which sends data to the respective memory location in the other stations. FL-Net uses standard Ethernet cable and network devices such as hubs, repeaters, etc). The GFL612
is a module that mounts in an S2E/S2T main or expansion rack. It allows the S2E/S2T to write data on the FL-Net and read data from the FL-Net. The GFL654 is a remote communications module that mounts in a V-Series rack with V-Series I/O. The GFL654 writes the status of its inputs on to the FL-Net and sets its outputs according to data received from the FL-Net. It supports up to 32 V-Series I/O modules.

ASCII Networks (Computer Link)

The S2E & S2T have two ports that can be used for ASCII communications, the RS232 programming port and the RS485 serial port. Both ports can function in the Computer Link Mode. The RS485 serial
port can also function in the Free ASCII mode. Learn more about computer link
