Toshiba T2E - Manual (Page 3)

Key Features
High speed processing
The Т2ЕЯ2Ы excels at applicartions where high speed
processing is required.
• 0.33 ps/contact • 0.44 ps/coii
• 1.2 ps/16*bit transfer • 1.63 ps/16*bit addition
Advanced instruction set
The T2E/T2N offers 24 basic relay-ladder instructions
and 192 function block instructions, including the
following.
• Arithmetic operation • Data manipulations
• Trigonometric functions • PID/ramp/intsgral
• Subroutine call • For-Next loop
• Averaging/filteiing • ASCII ** Hex conversion
• Floating-point math
Two programming Languages
The T2E/T2N supports two programming languages:
Ladder Diagram {LD) and Sequential Function Chart
(SFC). By selecting the appropriate language, or
coinbination of the two, program developrrtent time
can be greatly reduced.
Built-in clock/calendar
TheT2E/T2N has a real-time-clock/catendar function
(year, month, day, week, hours, minutes, seconds)
that can be used for performing scheduled
operations, data gathering with time stamps, etc,
Password protection
The T2E/T2N can be programmed with one of four
selectable protection levels.
• Level 1: No protect (normal)
• Level 2: Wrlting/moditying program prohibited
• Level 3: Level 2 plus viewing program prohibited
• Level 4: Level 3 plus writing data prohibited
Battery-fess operation fT2E)
The user-program is saved in a built-in Flash
memory. No battery maintenance is required.
Ethernet connection (T2N|
The T2N CPU modules (PU235N and PU245N) have
built-in Ethernet interface (10BASE-T). Through the
Ethernet, the T2N can communicate with higher level
controllers (computer, workstation, etc.) or other
PLCs with Ethernet.
High speed industrial LAN
The T2E/T2N can be connected to Toshiba’s high
speed industrial LANs (Local Area Networks)
TOSLINE-S20 and TOSLINE-FIO. Tbe TOSLINE
series are suited for real-time control data linkage.
Through these networks, the T2E/T2N can exchange
data with other Toshiba equipment, such as the
TOSDiC CIE system, other T-sehes PLCs, Large
Adjustable Speed Drives, General Purpose Inverters,
etc.
The T2N CPU module PU245N has the TOSUNE-
S20LP (Loop version) built-in into the CPU module.
The TOSLINE-S20LP is a high-ral¡ability double-loop
fiber optic S20 rtetwork.
Device Net
A DeviceNat scanner module Is avalable for the
T2E/T2M. The DeviceNet scanner module can
read/write data to any other manufacturer's ODVA
certified devices (I/O blocks. Inverters to include
Toshiba’s G3, air valve manifolds, sensors, etc.).
Flexible serial port
The T2En-2N has RS-232C or RS-485 serial
communication port, (It is optional in the T2E)
Using this port, one of the following communication
modes can be selected.
• Computer link mode: Connection with higher level
computer, MMl/SCADA system, modem, etc.
• Data link mode: Easy data linkage between two
T2Es, T2Ns, T2E—T2N or T2E/T2N—Super T1.
• Free ASCII mode: Active communication between
serial ASCII devices, (bar code readers, etc.)
Programmer port function
The T2E/T2N*s RS-232G programmer port supports
the T-series computer link protocol. This allows easy
connection to a higher level computer, an operator
interface unit, a modem, etc.
