2. Description
2.1 The Specification
PLC's of the TC600 series are freely programmable logic systems designed for control of work machines and technol ogical pr ocesses in vari ous
and div erse areas of producti on. They com plement the int egrated series of
modular and compact Tecomat PLC's with a small modular system
equipped with the driv e for m ounting on a U strip.
2.2 Compatibility
Although PLC's of the TC600 series are designed f or the smal lest appli cations, use properties of lar ge Tecomat P LC's remain ret ained. Signi fi cant
property is uniformness of technical and program means for creation and
debugging of the user program and uniformness of the highly ef ficient instruction set and system services with other Tecomat PLC's allowing for
evaluation of experience gained in applications of other Tecomat systems.
2.3 Communication
Two serial com muni cation c hannels f itt ed in a standar d m anner with optional int erf ac es and possibility of addition of a thi rd c om m unic ati on channel
allow for simultaneous local connection of intelligent peripheries equipped
with a serial com muni cation channel (readers of the bar code, printer s, frequency conv erters etc.), connec tion of the oper ation board and connection
to a comput er with the dev el opment env ironm ent or i nterconnect ion of indi vidual PLC's in the EPSNET industrial network. Up to 32 Tecomat PLC's,
Tecoreg regulators or other devices can participate in the network which
meet requirem ents of the EPSNET network (data terminal s, laboratory apparatuses etc.).
2.4 Distributed Control
Using the communication possibilities, it is possible to create extensive
systems with distri buted control by gradual connecting of autonom ous systems to the net work and by compl eti on of t he program shell without the necessity to interv ene in t he PLC's technical equipment . Another possibility is
additional interconnection of PLC's and collection of data for the central
monit or ing purposes.

2.5 The Building
The smallest f ully func tional PLC unit of the TC600 seri es is formed by
the basic module (BM). It is produced in six designs which dif fer in the num ber and type of inputs and outputs.
In types TC603 t o TC607, the after-num ber ( two digits af ter the dot)
determine the special B M function:
.00 common function of binary input s (after-number need not be given)
.01 4 interruption binar y inputs
.03 measuring by increm ental position scanner
.05 counter of type 3 (uni directi onal 16 bit counter with pre-selection)
.06 period and phase shift measurement
Optional part of al l BM t ypes are int erf ac es of t wo serial c om m unic ati ons
channels (CH1, CH2) f itted i n the standard design, addi tional data m emory
(DataBox) , and a third serial com munication c hannel (CH3) or analog outputs.

Memory of the user program is f orm ed by a part of the RAM m em ory of
CPU assigned for the user progr am, data and tabl es. When PLC is turned
off, the m emory is supplied by the built-in lithi um battery .
Source memory of the user program is formed by a part of the EEPROM
memory of CPU assigned for saving of a copy of the user program. The
memory power-independent, that is, contents of the memory remain retained even after the power supply of the PLC is turned off or when the
battery i s di scharged. Use of the source memory is contr olled by the user by
setting a parameter in t he P LC S E T mode (see Article 4.5) .
When the source mem or y is allowed, after exiting the SET mode, turning
on of the PLC power supply or restart, c ontents of the user program source
memor y is mov ed to the user program mem ory with which CP U works. The
functi on is used especially for backup of the user program. The m emory is
programmed from within t he devel opment environment direc tly in the PLC.

The behav iour is described in detail in Chapter 10.
The DataBox is an optional compl ement of the CPU, fi tted by the producer on the basis of an or der. I t ex t ends t he user accessibl e RAM m em ory
by 128kB or the data memory by 512kB. When the P LC is turned off, the
memor y is supplied fr om a bui lt-i n li thium batt ery. It is designed f or working
with greater amounts of data, f or exampl e for arc hiv ing of dat a on the controll ed process for a longer t ime period et c. The data can be writt en to the
memory or read, respectively, either by using the PLC user program or
through the serial line.
For support of the DataBox program attendance, there are thr ee user instructions available. The READDBX instruction is intended for reading of
data from DataBox into R regi sters, the WRI TEDBX instructi on is intended
for writing of data from R registers to the DataBox, and the SIZEDBX instruction serv es for identi fication of the DataBox size. Detailed descripti on
of function of instructions, their definitions, structures of the parameters
zone for i nstructions READDBX and WRI TEDBX and way of c alling of instructions in the user program are given on t he distribution disket te xPRO
which forms a part of the PLC delivery.
For serial communication with the DataBox, either CH1 can be used
which always operates in the PC m ode or c hannels CH2, CH3 set i n the PC
mode. To support serial communication with the DataBox, the
COMPLC.EXE program is av ai labl e which all ows for reading data f rom DataBox i nto a fi le or write dat a from a fil e to DataBox , respectiv ely, and test
size of memory accessible in the form of the DataBox. W orking with the
DataBox i s possible starti ng from the CO MPLC.EXE program version 1. 6.
The program, which is found on the x PRO distr ibuti on diskett e, must be r un
under the MS DOS oper ating system.
When the PLC power is turned of f, the RA M memory and RTC circuit are
supplied from a bui l t-i n l i thi um batt ery. Param et ers of the used batt ery al l ow

hours. In common operating conditions (operating temperature of 20 °C,
unidirectional operation at least) and typical power take-off of the backing
circui ts, the backup time is l imi ted by battery life (5 years at the minimum).
Voltage of the backup battery i s evaluated by the diagnostic system. In
the case the vol tage drops under 2.5 V, bit .0 of the S35 system regi ster is
set to the state log. 1. PLC cont inues with it s activ i ty unti l t he v oltage drops
under the minimum supply voltage of the RTC circuit. Evaluation of the
RTC circuit failure leads to bringing the PLC in the HALT mode and announcing the error message 80 0C 00 00.

4.4 Serial Communication Channels
Standard design of all PLC's of the TC600 series is equipped with two
comm unication channels. Thi rd communi cation channel is added per order
(see Article 2.5).
4.4.1 Serial Communication Channel 1 (CH1)
CH1 is designed for c onnecti on of t he PLC t o a superior system . The superior system most of ten repr esents a computer of the P C class perfor mi ng
the funct i on of a program m i ng devic e, visual isati on stat ion or contr ol devi ce
of the PLC network. It contains a complete set of the EPSNET network
servi c es. Detailed description of the services is given in the handbook
Communication of T ec om at P r ogr am m able Logic Controllers,
TXV 001 06.02.
CH1 is equipped with fix ed fit ted interface RS-232 without galvanic separation f rom internal circuits. Besides this, in all types of BM, CH1 can be
complem ented with a piggyback with int erface RS- 485 or RS-422. Opt ional
interf ace is impl ici tl y assigned to CH1. Interface RS -232 is assigned to CH1
automati cally by connecting the cable TXK 646 51.06. Together with connecting interface RS-232, the optional interface (if fitted) is disconnected
from CH1. For selection of the inter face ty pe, especiall y functi on of the superior dev ice is decisiv e, type of int erfac e of i ts serial comm unicat ion channel, connect ion distance, transmission speed and level of disturbanc es.

Parameters of the
RS-232 interface
4.4.1.1 Interface RS-232
Interface RS-232 ensures conversion of output signals of TTL level to
level defined by the specification V.28 (EIA RS-232), and of input signals
according to V .28 to the TTL l evel. I t allows for connec tion of two end devi ces in the duplex mode. I t is suitabl e for c onnection r ealised i n short di stance in an environment with low level of electrom agnetic distur banc es.
For the com municat ion, PLC's of the TC600 series use only bi nding ci rcuits of signal s TxD (Transmit Data), RxD (Receiv e Data), CTS (Cl ear To
Send), and RTS (Request To Send) of the standard RS-232 int er face.

4.4.1.2 Interface RS-485
Interf ace RS-485 ensures conversion of output signal s of t he TTL l evel
to lev el def i ned by t he specificat i on V.11 (X.27, EIA RS -485), and i nput signals according t o V.11 to the TTL lev el. Param eters of sym metric bi nding

Interface RS-422 of PLC's of the TC600 series ensures conv ersion of
output signals of the TTL level to lev el defined by the specification V.11
(X.27, EIA RS-422), and input signals according to V.11 to the TTL lev el.
Parameter s of symmetr ic binding ci rcuits of t he RS-422 int erface al low for
two-point connection of end dev ices in the duplex mode. It is suitable f or
connection reali sed in m edium distance i n an env ironm ent with hi gher lev el
of elec tromagnetic disturbances.
For the com municat ion, PLC's of the TC600 series use only bi nding ci rcuits of signals TxD ( Transm i t Dat a) and Rx D (Recei ve Data) of the RS-422
interf ace.

4.5 Setting of CPU Parameters
CPU parameters are set in the setting mode (mode SET). To set and
display paramet ers, the PLC front boar d is equipped with buttons SET and
MODE and a one-plac e seven-segment LE D display.
In the SET mode, all data are displayed in the rotational way, that is,
number 123 is displayed in such a way that digits 1, 2, 3 are l ighted gradually on the display, then there is a delay, and the whole sequence is repeated. Ev ery character i s displayed for about 0. 5 s and is separated f rom
the foll owing charac ter by a delay which ensures recognit i on of two ident i cal
characters display ed one aft er another (f or ex ampl e, di splaying of the num ber 111).
Switching t o the SET mode can be perf ormed by pressing butt ons SET
and MODE sim ultaneously whil e the PLC power supply is on. Buttons S ET
and MODE are held pr essed unti l the triple dash appears on the display. In
general it holds that by t he SET butt on we change setting of the param eter,
and by the MODE but ton we mov e t hrough i ndiv i dual paramet ers. Pressing
of the but ton is indic ated by lighting of the decim al point on t he display.
The SET mode m ay be term inated any ti me by sim ultaneously pr essing
the buttons SET and MODE. W e again hold the buttons SET and MODE
pressed until the t r iple dash appears on the display. Stat e of param et ers is
saved upon term ination of the mode in the power-independent m emory of
parameters, and the PLC switches to the HA LT m ode or som e of err or m essages may possibly be signalled.

Transport delay
When sett ing the param eter reply delay (in the PC m ode) or transportdelay (in the MAS mode), a message of the f ollowing type i s shown on the
display
with the f ollowing m eaning:
t- setti ng of the reply delay
2 - number of t he c hannel being set
10 - set delay/transport delay in ms
By shortly pressing the SET button, we increase the value of the delay/tr ansport delay by 1, by pr essing and holding the SET button (f or about
1s) we increase its v alue by 10. B y pressing the M ODE button we save the
set value and move to setting of another par ameter.
Optional reply delay serv es for solut ion of si tuations when the superior
system sending the message, cannot switch in time from transmission mode
to receiv ing m ode, and thus it cannot receiv e t he PLC's reply. By ex tending
the reply delay t he superior system gai ns time f or preparati on necessary to
start receivi ng of a reply .
The delay ti m e i s set in m s and m ay take values f rom 0 to 99 m s. Val ue
0 means that the mini mum reply delay shall correspond with the time necessary to transmit 1 byte, thus it depends on the set speed. Val ues 1 to 99
give the delay in milliseconds and are not dependent on the comm unicati on
speed.
The reply delay is set only for mode PC.
Optional transport delay serv es for soluti on of si tuat ions when the PLC i n
the role of the superior system is waiting for reply from a subordinate PLC
for l onger than 0.5 s for t he r eason of delay on the t r ansmission l ine, caused
by modem s etc .
Transport delay is set in multipl es of 100 m s and may take values from 0
to 6 s. Value 0 means that the superior PLC waits for the reply for the
maxi mum of 0.5 s (ti me of cycle of the subordinate PLC may not exceed
this value). Values 1 to 60 give the transport delay of 0.1 to 6 s which is
added to the v alue 0. 5 s. Values 61 to 99 set the m ax im um transport delay
of 6 s.
The transport del ay is set only f or mode MAS.
Setting of t he CTS
signal detection
When setting the param eter CTS signal detection, a message of the
following type is shown on the display
with the f ollowing m eaning:

Tecomat TC600
Detection of the CTS si gnal may be either of f or on. By pressing the SET
button we change the setting, by pressing the MODE butt on we save t he set
value and move to setting of another par ameter.
When detect ion of the CTS signal is on, bef ore t ransmission of the repl y
the PLC tests state of the CTS signal af ter setti ng the RT S signal . The repl y
is transmitt ed only if the CT S signal has the sam e v alue as the RTS signal.
This mode i s suitable for com municat ion vi a modems. The set reply delay
holds in this mode too, it is thus ensured that PLC shall not reply before t he
delay elapses even if the CTS signal is already set.
When CT S signal det ecti on is of f, PLC control s the RTS signal but does
not take into considerati on state of the CTS signal.
Detection of the CTS si gnal can be set for the PC mode of all channel s
and for the MAS mode f or channel CH2. For channels CH2 and CH3 in the
uni mode, detec tion of the CTS signal c an be set using the ini tiali sation table in the user progr am.
Default sett ing of
parameters
Parameter s of CH1 are implicitly set by the producer to the following
values: mode - PC, addr ess - 0, speed - 19.2 k b/s, delay - 0, CTS detection
- off
CH2 and CH3 are implici tly off.
4.5.2 Management of the user p rogram source memo ry
When setti ng parameters of the source memory, a message of the fol lowing type i s shown on the display
with the f ollowing m eaning:
EP - setting of the user program source memory

The source mem ory m ay be eit her of f or on. By pr essing t he S ET but ton
we change the setting, by pressing the MODE but ton we save t he set v alue
and move to setti ng of another parameter.
When t he param et er i s set to the of f v al ue, after t he PLC switches to t he
RUN mode, program stored in the user program memory i s run. When t he
parameter is set to the on value, after the setting mode is ended and in
every subsequent turning on of the PLC power supply, program from the
source memory is first moved to the user program m emory, and this program is then run in the RUN mode. The function serves especially for
backing of power-dependant memory of the user program.

5.1.1 Binary Inputs
Binary i nputs serve for c onnection of t wo-state signals of the contr olled
object to t he PLC. To increase f unctional rel iability, every input is galv anically separated by an optical el ement f rom i nternal ci rcuits and is equi pped
with a fi l ter. If the i nput i s exc it ed (cl osed), t hi s is signall ed by l i ghti ng of t he
LED diode. Input s are organized in groups with one c ommon connec tor. A
group of signals may be connected in one or the other polarity .

5.1.2 Binary Transistor Output s
Binary tr ansistor outputs serv e f or contr ol of two-state act ion and signal ling el ements, which require hi gh count and el. cl osing speed. To i ncrease
functional rel iability, every output is galvanically separated by an opti c al element fr om internal cir cui ts and is protect ed against short ci rcui t, overv ol t age
and rever si ng of polarity.
When connecting an external power supply of outputs, closing of individual outputs i s signalled by lighting of the LED di ode. By lighting, the common LED diode marked as BLK, signals blocking of outputs in the still
(open) state.
Outputs are organi z ed in groups with one common connector.

5.1.4 Analog Inputs of TC605, TC606, TC625, TC626 Modules
Analog inputs serve for connection of up to four analog signals of the
controll ed object to the PLC. They are i ntended especial ly f or processing of
analog signals with normalized current or v oltage level. Input circuits are
galvanically connected wit h internal P LC c ontrol ci r c uits.
Inputs are arranged in a gr oup with one common connector of t he analog
ground. Ev ery input can be set indi viduall y by a jumper f or the voltage or
current signal source. T he m easurement range i s set by a pr ogram . T ype of
input and the measurement range c an be selected for every i nput independently of other inputs.
Value of the i nput v ar iabl e i s passed in the FS form at (F ul l S cal e). V alue
0 of the input data corresponds with the lower limit of the measurement
range, the maxi mum v alue of t he input data 4095 cor responds with the upper limi t of the measurem ent range. E x ceedi ng of the c onv er ter r ange is not
signalled. Conversion to technical units is performed on the user program
level. The FS format provides the highest possible resolution.

5.1.5 Analog Inputs of the TC634 Module
Analog input s serve f or connection of up t o eight analog signals of the
controll ed obj ect t o the P LC. T hey are i ntended especial l y f or m easurem ent
of temperatures using passive resistance temperature scanners, and for
processing of analog signal s with normali zed current or v ol tage lev el. Input
circui ts are galvanically connected wit h the PLC internal control c ircuit s.
Inputs are fi xed-confi gured as differenti al ones. Ev ery input can be set
individually using a jumper for direct-current voltage or current signal
source. Measurement r ange and form at of the input variabl e val ue ar e set in
a program. Input type, m easurement range and f ormat of t he v alue of input
data can be selected for every input independently of other inputs.
To supply power to passiv e resistance detector s, an internal power supply prov iding speci fic current 1 mA is av ailable, which is switched in m easurements automatically to one of the two output c lips.
The modul e ensures fil tering off of the disturbance com ponent of input
signals, protect ion of input circ uits, conv er sion of t he analog v ol tage or cur-
rent input level to the binary value, and conv ersion of the value into the
chosen form at.

5.2 Special Functions
Basic BM functions of TC603 to TC607 can be extended by special
functions.
Special functi ons use standard-f it ted i nput s, or possibly PLC out puts, but
their attendance requires more complex shell al gorithms or complementation of the basic technical equipment of the input and output unit. These
servi ng algorithms are real ized by the system program , thus servi cing performed by the user program r emains sim ple.
Special f unct ions are compl em ented t o select ed BM t ypes per order (see
Article 2.5). Always one special func tion may be c omplemented only.
5.2.1 Interrupt Inputs
Interrupt inputs allow for fast access to user programs for servicing of
time critical operational states of the controlled object, and processing of
fast changes of input signals processing of which by standard binar y inputs
is not possible.
Change of state of binary inputs DI0, DI1, DI2 or DI3 is done by the i nterruption process P42 which m ay be used to service the stat e. At the same
time, flags are set determining source of the interrupt in the STAT state
word. Activ ation of the interruption process from individual inputs can be
controlled by setting the relevant bits of the CONT control word. In ev ery
input, it is possible to individual ly set the signal edge that activates the int er rupt.
Interrupt inputs do not disturb neither limi t basic func tions of inputs DI0 to
DI3 described under i tem 5.1. 1.

5.2.2 Counter of Type 3
Counter of type 3 is a unidirectional 16 bit counter of external ev ents
equipped with pre-selection, counting (CLK) and resetting input (RESET).
The counter can operat e as a freely running counter (in t he range of 0 to
65535) or self- filling counter (in the range of 0 to pre-selection).
The binary input DI0 is used as the CLK input, binary input DI1 i s used as
the RESET input. When the RESET input state corresponds with log. 1
(closed input), the counter counts ascending edges of signals on the CLK
input. W hen the RESET input state corresponds with log. 0 (open input ), t he
counter is reset permanently. Overf low of the count er range or reaching of
the pre-selection will evoke interruption process P44 of the user program. At
the same ti me, setti ng of rel evant bits in the ST AT state word of the counter. Reset and blocking of t he count er can be al so done f rom withi n t he user
program by sett ing the relevant bit in t he CONT control word of the count er .
Use of binary i nputs as the counter inputs does not di sturb neither lim it
their basic function described under item 5.1. 1.

5.2.3 Admeasurement of P osition by the Incremental Enco der
The functi on of admeasurement by the increm ental encoder i s designed
for processing of incremental encoder signals with outputs with an open
collector.
In the admeasurement, it is operated with signed ar it hm eti cs i n the range
of long (4 byt es) between li m it s -2147483648 (8000 0000h) t o +2147483647
(7FFF FFFFh) with 0 in between. It allows for adm easuring with r esolution
of the m ovem ent di rect i on, sett ing of one pre-select i on for every m ovem ent
directi on, resoluti on of positi on towards pre-selections and searching out of
the refer ence point. Af ter reachi ng of a pre-selecti on, ov erfl ow or under fl ow
of the range, relev ant bits are set i n the STAT state word and the interruption process P44 is evoked. Control of admeasurement is performed
through the CONT state word.
To connect the enc oder, binar y inputs DI0 ( direct output of trac e 1 of incremental encoder), DI1 (direct output of trace 2 of increm ental encoder),
and DI3 (direct output of the zero pulse of incremental encoder ) ar e used.
Use of binary i nputs f or connecti on of increm ental encoder does not disturb neither lim it thei r basi c function described under item 5.1. 1.
