Programmable Controllers

T1-16S PLCs

Expandable Micro Programmable Controller

T1-16S PLCs --------------  and -------------- Operator Interface Stations

The T1-16S series are micro programmable controllers with optional add-on expansion I/O modules. Their communications capability, advanced instruction set, and large program and data memory make it an excellent choice for applications previously requiring larger more expensive programmable controllers. The T1-16S's high-speed performance makes sophisticated machine control applications a snap. T1-16S systems can expand two ways;  use plug-in cards or an expansion unit.

T1 connections

Advanced applications

Motion control

The T1-16S has two high-speed (5k pps (pulse per second)) counter inputs. The counters are independent of each other and of the CPU scan for counting applications requiring high-speed compare, reset, and strobe. The counters can also work together as a quadrature counter to count a 2-phase pulse encoder signals. While In the quadrature counter mode, it works all the way up to 20,000 cps (counts per second).

The T1-16S also has a pulse output function (5,000 pulses per second max) For generating variable frequency pulse trains, CW, and CCW. Handy for driving a stepper motor or providing a clock. By using these functions together, a good programmer can provide an inexpensive motion control system with just a T1-16S!

PID (Proportional, Integral, and Derivative) control function

Don't be scared off by the name, PID loops are easy with Super T1 PLCs The advanced PID (Proportional, Integral, and Derivative) control function allows optimizing analog feed back loops. Multiple PID loops can be used, limited only by the max allowable I/O. A typical application would be driving a proportionally controlled heater to keep very accurate temperatures with quick response times.  PID loops can be applied with almost any analog feed back loop including applications as diverse as flow, level, pressure, PH, Humidity etc.

Data Linkage between Super T1 PLCs

Using the RS485 port and the data link mode, two T1-16Ss can exchange data each other (16 words input and 16 words output). The update cycle for the total 32 words is approx. 50ms. No user program required for this data linkage. This is industrial networking on the cheap!

ASCII Communications

The free ASCII serial communications allow interfacing with all sorts of Serial devices from RFID systems, barcode readers, fingerprint scanners, printers, scales, intelligent sensors etc. Toshiba PLCs have a simple ASCII protocol that gives you access to all the registers via a serial port. Several third party user interface packages support it - or ask Transtronics about writing custom a GUI (graphic User Interface) for your application. Do-it your-self-ers will want to download the computer link manual

Motor Speed Drives

The RS485 port can also supports a special mode to exchange data with Toshiba's Inverters (ASDs), (VF series including the A7, G7, and S9 types). This mode allows the T1-16S to talk to the Inverters without any special communication program so you can easily monitor Operation frequency and status and easily control Run/Stop/Jog, Forward/Reverse, and drive frequency!

Understanding T1 PLC part numbers

TAR116S6S  T - T series, AR - AC input, 1 - T1 series, 16 - 16 I/O, S - Super, 6 runs on 120Vac, S - standard version

T DR 1 16 S 6 S
T = T Series DR = DC I/O version 1 = T1 Series 16 = 16 IO S = Super 6 = uses 120/240Vac  Power S = enhanced version
AR = AC I/O version1 28 = 28 IO 2 - = older
version 2
3 = uses 24Vdc  Power C = economy version 3
40 = 40 IO
1 AC IO is avoided for cost and safety reasons - if possible use DC I/O. If you need to sense just a couple of AC inputs look at our Logic level converters.

2 The "-" or "*" or 28 versions should not be used for new designs
3 The C version doesn't have RTC or RS485
