Expansion

The T1-16 and T1-28 are fixed I/O non-expandable controllers.
The T1-40 and T1-40S, however, provides additional flexibility. They are expandable in
three ways, option cards, expansion rack and expansion unit.
The T1-40/T1-40S can hold two option cards. These are approximately 1/2 the size of a
credit card. Also, the T1-40/ T1-40S can be connected to either one expansion rack or
one expansion unit. The expansion rack (2-slot type or 4-slot type) allows the T1­40/T1-40S to use most T2 series I/O modules. The expansion unit is a fixed I/O unit. It
has 32 I/O points (16 inputs and 16 outputs).
If two 16 points option cards are inserted and t he 4- slot expansion rack with four 64
points modules is connected to the T1-40/T1-40S, it can control up to 328 points.

Sophisticated machine control applications require high speed data manipulations. The
T1/T1S is designed to meet these requirements.

1.4 ms per contact

·

4.2 ms per 16-bit transfer

·

The T1/T1S also supports int errupt input function (DC input type only). This allows
immediate operation independent of pr ogram scan.

High performance software:

The T1 offers 17 basic ladder instructions and 76 function instructions. The T1S offers
21 basic ladder instructions and 99 function instructions.
Subroutines, Interrupt functions, Indirect addressing, For /Next loops, Pre-derivative
real PID, etc. are standard on the T1/T1S. These f unct ions allow the T1/T1S to be
applied to the most demanding control applicat ions.

Battery-less operation:

The T1/T1S has a standard built-in EEPROM, permitting operation without need of a
battery. Also, the variable data can be written into and/or r ead from the EEPROM,
providing completely maintenance-free back-up operation.
This function is an important feature for OEMs, because it can eliminate the need for
changing the battery every few years. The cost of the battery is also eliminated.

WARNING

(1) Current sour ce / sink selection on the T1-16 dry contact input

The input current flow direction (sour ce or sink) of the T1-16 dr y contact input can be
selected by setting the jumper plug on t he T1-16 printed circuit board as shown below.
The factory setting is current source. Refer to sect ion 2. 4. 1 for specifications and signal
connections.

The tool for opening the
cover is attached on the
back of the T1-16.

Remove the tool from the
unit.

Configure emergency stop and safety interlocking circuits out side t he
T1/T1S. Otherwise, malfunction of the T1/T 1S can cause injury or serious
accidents.

!

CAUTION

(1) T ur n off power before

opening the cover.

(2) T ake care not to touch

any electrical parts on
the board. Static
electricity can cause
damage.

(3) Use a pair of tweezers

to change the jumper
plug setting.

Put the tool on the side of
the unit so that the marks

<

on the tool and the unit

are aligned.
Push the tool to unhook

the cover. Then remove
the cover.

(2) Minimum ON/O FF time of the input signal

The following conditions guarantee corr ect reading of the ON/O FF state of the input
signal:
Input ON time: ON delay time + the time for one scan
Input OFF time: OFF delay time + the tim e for one scan
The ON and OFF times of the input signals must be longer than these inter vals.

(3) Increasing t he contact current

The reliability of some contacts cannot be guaranteed by the specified input current. In
this case, install an external bleeder resistor to incr ease t he contact current.

(5) Countermeasur es against leakage current

When a switch with an LED or an AC output sensor is used, the input sometimes cannot
recognize that the switch is off due t o t he current leakage. In t his case, install a bleeder
resistor to reduce input impedance.

Bleeder resistor

6F3B0250

Bleeder resistor

R

V

DC input type AC input type

Select a bleeder resistor according to t he following criteria:
(a) T he voltag e between the input terminals must be lower than the OFF voltage

when the sensor is switched off.
(b) T he cur r ent must be within the allowable range when the sensor is switched on.
(c) Calculate the wattage of the bleeder r esist or by mult iplying the current when the

sensor is switched on times three.
Note) The above solution cannot be applied to the T1-16 dr y contact input .

(6) Countermeasur es against induced current

With ac input signals, if the external cable is long or if a multi-core cable is used, an
induced current can flow from the char ged wire to the open wire, in proportion to the
capacities of the cables. In this case, sometimes the voltage reaches the level of the ON
input even though the contact is open, causing t he input to malfunction for no apparent
reason.
The usual practice when this happens is to reduce input impedance. Install a resistor or a
resistor and capacitor between the input and common terminals, or use shielded cables.
Such precautions are necessary when dealing with a large number of ac input signals.

WARNING

!

CAUTION

Configure emergency stop and safety interlocking circuits outside the T1/T1S.
Otherwise, malfunction of t he T1/T1S can cause injury or serious accidents

1. Turn on power to the T1/T1S befor e t ur ning on power to the loads. Failure
to do so may cause unexpected behavior of the loads.

2. Configure the external circuit so that t he exter nal 24 Vdc power required
for the transistor output circuits and power to the loads are switched on/off
simultaneously. Also, turn off power to the loads before turning off power to
the T1/T1S.

3. Inst all fuses appropriate to the load current in the external circuits for the
outputs. Failure to do so can cause fire in case of load over-current.

(1) 2 points of solid- s t at e output

The leading 2 points of output (Y020 and Y021) are solid-state outputs, transistors on the
DC input types and triacs on the AC input types.
These solid-state outputs are suited for frequent switching applicat ions.
Note that the specifications of the solid-state outputs and other out puts (relays) are
different.

(2) Switching life of output relays

Expected relay life is more than 100,000 electrical cycles at rated maximum voltage and
current, and more than 20 million mechanical cycles. The expected contact life (electrical
cycles) is shown on the table below.

5.1 Operation modes

The T1/T1S has three basic operation modes, the RUN mode, the HALT m ode and t he
ERROR mode. The T1/T1S also has the HOLD and RUN-F modes mainly for system
checking.

6F3B0250

RUN:

HALT:

ERROR:

The RUN mode is a normal control-oper ation mode.
In this mode, the T1/T 1S reads external signals, executes the user program
stored in the RAM, and outputs signals to the external devices according to the
user program. It is in the RUN mode that the T1/T1S performs scans the user
program logic, which is the basic operation of a PLC.
In case of the T1S, program changes and EEPROM write are possible while
the T1S is in the RUN mode. Ref er to section 6.9.
On the other hand, in case of the standard T1, program changes and
EEPROM write are not possible in the RUN mode.

The HALT mode is a programm ing mode.
In this mode, user program execution is st opped and all out puts are switched
off.
Program loading into t he T1/T1S is possible only in the HALT mode.
For the standard T1, prog r am changes and EEPROM write are possible only
when the T1 is in the HALT mode.

The ERROR mode is a shut-down mode as a result of self-diagnosis.
The T1/T1S enters the ERROR mode if internal t r ouble is det ected by self­diagnosis. In this mode, prog r am execution is st opped and all outputs are
switched off. The cause of the shut-down can be confirmed by connecting the
programming tool.
To exit from the ERRO R m ode, execute t he Error Reset command from the
programming tool, or cycle power off and then on again.

HOLD:

RUN-F:

T1/T1S User’s Manual

82

The HOLD mode is provided mainly for checking the external I/O signals.
In this mode, user program execution is st opped, with input and out put
updating is executed. It is therefore possible to suspend program execution
while holding the output state. Moreover, a desired output state can be
established by setting any data by using the programm ing tool.

The RUN-F mode is a forced RUN m ode pr ovided for program check ing.
This mode is effective when using the expansion I/Os.
Deferent from the normal RUN mode, the RUN-F mode allows operation even
if the registered option cards, expansion unit and/or I/O modules are not
actually mounted.

The user program and the data stored in the EEPROM is transferred to the RAM when
power is turned on. Subsequent program execution is done based on the RAM contents.
Program editing is also performed on the RAM contents.

Therefore, if the program is modified, i t i s necessary t o i ssue t he EEPRO M Wri t e

In case of the T1S, Special register SW55 is used to specify the number of Data registers
to be stored in the EEPROM. The allowable setting value is 0 to 2048.
The table below shows the correspondence between the SW55 value and Data registers
saved in the EEPROM.

When the EEPROM Write command is executed, the T1S checks the value of SW55 and
saves the Data registers into the EEPROM depending on the SW55 value. The value of
SW55 itself is also saved in the EEPROM.
At the initial load or the EEPROM Read command is executed, the T1S checks the value
for SW55 in the EEPROM and transfers the corr esponding number of data to the Dat a
registers of the RAM.

NOTE

(1) When the data stor ed in t he EEPRO M (Data registers) are used, these

registers should be specified as retent ive. O therwise, these data are
transferred fr om EEPROM to RAM, but then cleared to 0 at the
initialization.

(2) T he dat a in t he retentive registers are stored in RAM and backed up by

built-in capacitor. The back-up period is 6 hours or more at 25 °C (T1), or
168 hours or more at 25 °C (T1S).
The T1/T1S checks t he validity of t he retentive data at the power-up
initialization, and if they are not valid, sets the special device (S00F) to ON.
Therefore, it is recommended to check the status of S00F in the user
program and to initialize the retentive registers if S00F is O N.

(3) T he r et entive registers can be set by the programm ing tool for RW, T, C

and D registers. The reg ist er s from address 0 to the designat ed addr ess
for each type are set as retentive reg ist er s. Refer to the separate manual
for the programm ing tool for setting t he retentive registers.

(4) T he input force and the forced coil are functions for progr am debugging.

5. Operating System Overview

Self-diagnosis:

Checks the proper operation of the T1/T1S itself. If an error has detected and cannot be
recovered by re-tries, the T1/ T1S moves into ERROR mode. For the self-diagnosis
items, refer to sect ion 10. 2.

Mode control:

Checks the mode control switch status and the m ode cont r ol r equest commands from
the programming tool.
The scan mode - floating scan or fixed-time scan - is also controlled hear.

NOTE

The floating scan:

When one scan is finished, immediately starts the next scan. The scan time is
shortest, but may vary depending on the program execution status.

Scan timeScan time Scan time

The fixed-time scan:

The scan operation is started every user-specified time. The time setting range
is 10 to 200 ms (10 ms units). If an actual scan needs longer time than t he
setting time, it works as the floating scan.

Program check:

At the beginning of the RUN mode, the user progra m is com p iled and it s validity is
checked.

I/O update:

Reads the external input signals into the external input devices/registers (X/XW), and
sends the data of the external output devices/registers (Y/YW) to the external output
circuits. Then the outputs ( r elays, etc. ) changes the states and latches until the next I/O
update timing.
The states of the forced input devices are not updated by this operation.

Timer update:

User program execution:

Executes the programmed instructions from the beginning t o t he END instruction.
This is the essential function of t he T1/T1S.
In this section, only the main program execution is mentioned. For other program types,
such as timer interrupt, etc., refer to section 6.5.

Peripheral support:

Supports the communications with the program m ing tool or an external devices
connected by the computer link funct ion. The time for this operat ion is lim it ed within
approx. 2 ms in the floating scan mode, and within allowable idling time in the fixed-time
scan mode.
In case of the T1S, if the special relay S158 is set to ON, the peripheral support priority
mode is selected. In the peripheral support pr iority mode, the peripheral support time is
not limited. As the result, t he com m unicat ion r esponse is im pr oved although the scan

6.1 Devices and registers

The T1/T1S program consists of bit-based instructions that handle ON/OFF information,
such as contact and coil instructions, and regist er - based ( 16-bit) instructions, such as
those for data transfer and arithmetic operations.
Devices are used to store the ON/OFF infor m at ion of contacts and coils, and register s
are used to store 16-bit data.

Devices are divided into six types:
X External input devices

Y External out put devices
R Auxiliary relay devices
S Special devices
T. Timer devices
C. Counter devices

6F3B0250

Registers are divided into eight types:
XW External input registers

YW External output registers
RW Auxiliary relay registers
SW Special registers
T Timer registers
C Counter r egisters
D Data r egisters
I, J, K Index registers

Device and register numbers

X devices share the same memory area as XW registers. Device X014, for example,
represents the number 4 bit in the X W01 regist er .

Bit position / Number
