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.

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 mem ory rem ain ret ained ev en when the PLC power supply i s turned off
or if the battery is discharged.
The scratchpad m emory is a part of the CPU RAM memory accessible to
the user in the f orm of i nput i mages (regi sters X), outputs i mages ( registers
Y), system (S) and user registers (R). Preserving of the scratchpad cont ents
after t urni ng of f of the PLC power supply and restart s i s program - contr oll ed.
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

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

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.

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 transport

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:
CTS - setting of the CTS signal detection
2 - num ber of the channel being set
on - det ec tion on
19 TXV 138 08.02

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
off- m emory off (default val ue)
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.

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

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.

6. Packaging
Individual BM's and EM's are packaged together with instructions according to t he internal pac k aging regulation into boxes provided with a fixing
insert. Outside pac kaging is reali zed according t o the order ex tent and way
of transport , i n a tr ansport cover provided wit h tr ansport tags and other dat a
necessary for the t r ansport .
7. Transport
Transport from the producer is performed in a way agreed upon at ordering of the product. Transport via the customer's own means must be
perform ed using roof ed transport m eans, i n a position gi v en on the tag pr esent on the cover. The box must be stored in such a way so that no unprompted movement and damage of the outside cover can occur. The
product must not be exposed to direct eff ect of weather conditions in the
course of the transportation. The transport may be realized under temperatures -25 °C to 70 °C, relat iv e hum idi ty of 5 % to 95 % (non-condensi ng),
and pressure >70 kPa.
8. Storage
Storage of the product is all owed only in clean ar eas without conductiv e
dust, aggressive gases and vapours, under temperatur es of - 25 °C t o 70 °C,
relati v e humidi ty 5%, and pressure >70 kPa. At storage, sudden changes in
temperat ure neither form ation of dew on the product may occur . Long-term
storage of the product under tem peratures cl ose to the upper l im it of the al lowed temperature reduces capacity of the backing battery. Most suitable
storage temperature is 20 °C.
9. Installation
9.1 Principles of Proper Installation
Tecomat PLC's of the TC600 series are built-in devices designed for
being mounted in closed cases. From the viewpoint of correct function of
the system, it is necessary to choose the size and design of t he case so that
by the constructi on arrangement , it i s possible to lim it as m uch as possibl e
the eff ect of especially power parts of the dev ice on t he PLC. Li mit ation of
the disturbi ng eff ect can be achiev ed by suit able dislocat ion of parts of the
equipment, by their proper interconnection and elimination of inductive
loads.
In general the following princi ples apply:
from the vi ewpoint of di sturbanc es and cooli ng, i t is m ore sui tabl e to use
a metal c ase than a plastic one
t he PLC should be place if possible in an area spatial ly separated from
powerful closing elem ents of the cont r olled technology
conductors should be laid i n cable t roughs on a def ined basis, f orm ati on
of bights should be prevented
par allel running of conductors of the power supply, analog signals, PLC
inputs and outputs with conductors of the power alternating part of the
distribut ion should not be real ized unnecessarily
shielding of leading-in cables of analog inputs and outputs should be
connected with the fram e by the short est connect ion possibl e, form ed di -
rectly by the shielding plied apart
cover of modul es (a protect iv e connect or) should be connect ed as cl ose
as possible with the non-liv e part of the case or by the short est possible
independent connection with the protective connector of the case, the
connection should be realized by a conductor with the minimum cross
section of 2.5 mm

9.2 Ensuring of the Required Operational Temperature
In cases without for ced inside air c irculat ion, the PLC m ust be placed i n
such a way so that the distance between the bottom and top si de of the PLC
and inside sides of the case is at least 100 m m . I f t his cannot be ensured by
good unprompted air circul ation, it is necessary to ensure air circulati on by
buildi ng in a v entilat or. The m axim um all owed air temperat ure entering t he
regulator is 55 °C. The PLC itself participates in the output losses by the
maximum of 13 W (20 VA) of the power input, typically t he loss of 0.25 W at
every closed binary input and 0.2 W at every closed transistor output.
Losses at closed relay outputs are i nc luded the PLC power input.

9.5 Connection of the PLC Inputs and Outputs
Wi th the exception of the protectiv e grounding connector and the CH1
RS-232 interf ace, PLC inputs and outputs are connected using rem ovable
termi nal boards which are inserted into t he appropriate socket plugs of i nputs and outputs. The screw part of the terminal board is constructed for
connection of a full conductor with cross section up to 1.5 mm
with cross section up to 1 mm
of the f ul l conduct or i s 0.2 m m
2
. The mini mum recom mended cross section

, of t he wire 0.5 m m2. Term inal boards are a
part of the PLC additional package.
Connection ter minal boar ds are not pr otected against exchange by any coding element, c hec k the connection before putting them into operat ion!
9.5.1 Connection of the Protective Connector
The PLC protective connector must be interconnected with the inside
protective connector of the case. Interconnection m ust meet requirements
* +, IEC 364-5-54:1980). From t he vi ewpoint of disturbances, in cases with the m etal mounti ng board it is suitabl e to connect
the protecti ve term inal board with t he mounting board by the shortest connection possible. The protect iv e c onnec tor is mark ed with the label 417-IEC-
2
or a wire
PLC power supply
can also be used for
supplying of binary
inputs
5019-a
.
9.5.2 PLC Power Supply
Power supply of the PLC, input and output ci rcuits, m ust be in the ov er - 33 0420 (eqv IEC 664:1980,
IEC 664A:1981).
The power supply must m eet c ondit i ons of t he SELV supply acc ordi ng t o
++,$+++.//01
Between the primary and secondary winding of the transformer, a Cu
shielding f oil must be wound up, connec ted with t he inside prot ectiv e t ermi nal board of the case or the winding must be arranged spati ally in such a
way so that the mutual capacity between the windings is minimized. It is
suitable to insert switches int o the supply lead whic h m ake work on program
debugging, m aintenance and possible repairs easier.
The power supply v oltage of the P LC, 24 V~ ±20%, 50 - 60 Hz ±5% or
24 V- ±20 %, is connected to c onnectors M1 and M2 of t he term inal boar d
marked as POW E R INPUT. In connect ion of the di rect- current supply, v oltage polarit y does not matter. P ermanent ex ceeding of the tol erance upper
lim it m ay cause breaki ng of the v olt age protecti v e elem ent of the PLC converter. For dimensioning of the supply, it is necessary to consider the
maxi mum input of 13 W (20 VA), which also contai ns input of coils of the
relay of binary relay outputs.
Switches of input circuits m ay be supplied from the same power supply
as the BM internal converter. Input of the closed binary input is typically
0.25 W (0.25 VA). For connection of the binary inputs supply see item 9.5.3.
Circuit s closed by binary output s must be supplied f rom an independent
power supply or at least f rom an i ndependent transf orm er winding. The supply must be dim ensioned accordi ng to the conc rete input of t he loads. Input
of the output transistor cir cuit is ty picall y 0.2 W for cur rent of 1 A. For connection of the binary outputs power supply see items 9.5.4 and 9.5.5.

10. Attendance
10.1 Instructions for Safe Attendance
When t he power supply i s on, it i s not all owed to di sconnect and connec t
supplying term inal boards neither to connect and disconnect indi v idual conductors of t he termi nal boards.
When pr ogr amming controlling PLC algorithms, the possibility of an error
in the user program cannot be exc luded the result of which m ay be unexpected behav i our of t he contr oll ed obj ect the consequence of which m ay be
originat ion of break down situation and in t he extreme case also endangering
of persons. In attendance t o the P LC, especi all y i n t he testi ng stage and debugging of new user programs with the controlled object, it is unconditional ly
necessary to be concerned with great er c ar efulness.
The producer is not r esponsible for damages caused by
improper attendance or inc or r ec t algorithm of the user
program.
10.2 Putting into Operation
When put ting the PLC i nto operati on for the f irst t ime, i t is necessary to
meet the following procedure:
check correct ness of the c onnecti on and volt age value of t he PLC power
supply
check interconnection of the PLC protective connectors with the main
protecti ve connector of t he distribution board or case
check correct ness of the c onnecti on and volt age value of t he power sup-
ply of input and output c ircuit s
turn on the P LC power supply
10.3 PLC Initialization
After the power supply is turned on, the PLC tr ansfers to t he starti ng sequence. The starting sequence is used for testi ng of the pr ogram and technical equipment of the PLC and setting of the PLC to the defined initial
state.
In the course of the starting sequence, version of the system program
equipment is gradually shown on the displ ay , for exampl e:
PLC binary outputs are blocked in the still state in the course of the testing (the BLK si gnal is li ghted in the f ield of binary out puts) and analog out puts are set to zero.
The starting sequence may be terminated by transferring to the RUN
mode and display ing
,
by transferr ing to the HALT mode and displaying
,
by transferr ing to the SET mode (see Article 4.5) or transferring to the HALT
mode with di spl ay ing of t he er r or message
, or full error code, for example .

Mode RUN

Mode SET
Technical equipment of TC600 PLC
10.4 Operational Modes
The PLC may oper ate in three basic modes.
The RUN mode is a common operati onal mode i n which val ues of input
signals are scanned, operations given by the user program algorithm are
perform ed, and PLC outputs are set. The PLC transfers in t he RUN mode
automatically after proper termination of the starting sequence. In the
course of the mode, let ter G is shown on the display.
The HALT mode is an operational m ode i n which t he user program i s not
run and the PLC is in a defined state. The PLC transf ers to the HALT mode
automati call y when a critical er ror is ev aluat ed during t he starting sequence
or in the course of control and after t er mination of t he S E T mode.
If t he PLC transfers to the HALT m ode from t he starting sequence, binary outputs remain blocked in the still state, analog outputs remai n set to
zero and code of the error message is shown on the display.
If the PLC transfers in the HALT mode after termination of the SET
mode, bi nar y outputs remai n blocked in t he still state, analog outputs remain
set to zero and let ter H or an error message are is shown on the display.
Mode HALT evoked by term inati on of the SET mode can be ter minated ei ther by the superior system or by turning of f and on of the PLC power supply.
If t he PLC transfers to the HALT m ode in the course of control, bi nary
outputs are set in the still state and blocked, analog out puts are frozen in the
state in which they were in the moment of transferr ing to the HALT mode,
and an error message is shown on the display.
For transf er to the HALT mode controlled by the user see item 10.4.1.
The SET m ode serves f or setting of comm unicati on paramet ers, setting
of the tim e circui t, and control of act iv ati on of the source user program . Entrance in the m ode is controll ed by the attendanc e persons at turning on of
the PLC power supply. In the course of the mode, binary outputs are
blocked in the still state, and analog outputs are set to zero. Af ter termi nation of t he SET mode, the P LC transfers automat ically t o the HALT mode.
Detailed description of setting of the PLC parameters is given i n A r ticle 4.5.
Transfer from the
HALT to RUN mode
Transfer from the
RUN to HALT mode
10.4.1 Change of Operational Modes
Transfer between RUN and HALT modes controlled by the attendance
persons is possible only using the superior system equipped with an integrated dev el opm ent envir onm ent f or program m i ng of the Tec om at PLC's or
with a moni tori ng and cont rol li ng progr am . T ransf er between t he m odes has
practical foundation only in the phase of debugging of the user program . In
general, i t can be said that transf er between the modes if a device i s connected, especial ly modif ication of t he PLC activ ity at transfer bet ween the
modes, requires perfect knowledge of the control led obj ect as well as of the
PLC, and careful considerat ion of possibl e c onsequences.
When changing the PLC operational modes, some activities are perform ed on the standard basis, and some can be perf orm ed opt ional l y. In t he
case that the change of the PLC m ode is done using the PLC dev elopm ent
envi ronment, optional activi ties at changing of the mode are a part of t he
development envir onment m enus.
10.4.2 Activities Perfo rmed at Changing of the PLC Mode on the
Standard Basis
In transfer from the HALT to RUN mode, the following is performed:
test of the user program integrity
check of software configuration given in the user program (see item
10.5.2)
running of the user program solv ing
In transfer from the RUN to HALT mode, the following is performed:
stopping of the user program sol vi ng
setting of outputs i n a defined stat e

Options at t r ans fer
from HALT t o RUN
Options at t r ans fer
from RUN to HALT
If a cr itical er ror occurs in the course of activ ities perf ormed at transfer
between the modes, the PLC sets the HALT mode, shows on the display t he
error code, and expects removal of the error c ause.
Do not in any case repl ac e stopping of control using the
HALT mode by function of the button CENTRAL STOP.
10.4.3 Optionally Performed Activities at Change of the PLC M ode
At transfer f rom the HALT m ode to RUN, it is possible to opti onally perform the following:
resetti ng of the PLC err or
warm or cold reboot
blocking of out puts at solv ing of t he user progr am
At transfer f rom the RUN mode t o HALT, it is possible to opti onally perform the following:
resetti ng of the PLC err or
setting of the PLC out puts to zero
At resetti ng of the PLC err or , the whole PLC error stack is reset.
The request for blocking of the P LC outputs causes the program to be
solved with disconnect ed binary out puts. Bl ock ing of the output s is indi cat ed
by the BLK LED di ode in the f ield of binary outputs.
At setting of the outputs to zero, all im ages of t he PLC bi nar y outputs are
set to zero.

10.4.4 Restarts of the User P rogram
Restart means such a PLC acti vi ty, the pur pose of which is prepare the
PLC for solvi ng of the user progr am . Under nor m al c ir cum stances, restar t i s
perform ed after turni ng on of the power supply, and at ever y change of t he
user program.
The systems distinguish two types of restart, warm and c old. Warm restart all ows for ret aining of t he values in t he remanent part of t he scratchpad. Cold restart is always performed with full m emory initialization.
During restart, the following is performed:
test of integrity of the user program
resetti ng of the whole PLC scrat c hpad
resetti ng of the remanent zone (onl y at cold restart )
setting of the remanent zone (onl y warm restart)
ini tialization of system registers S
ini tialization and chec k ing of PLC inputs and outputs
When t he user program is run without a restart, onl y test of integri ty of
the user program is performed and checking of the PLC i nputs and outputs.
After being turned on, the PLC perf orms the restart type chosen by the
user. If damage of data found in the remanent zone of the scratchpad
memor y is evaluated, PLC perform s cold restart without regard t o the chosen restart type.
Depending on the perf orm ed restart, t he planni ng uni t of user processes
P operates as well. If you hav e perf orm ed warm restart at transf er f rom t he
HALT to RUN mode, aft er transferring to t he RUN mode the user process
P62 is solv ed fir st (if pr ogramm ed). At col d restart, af ter transferri ng to t he
RUN mode the user process P63 is solved f ir st (i f program m ed). If onl y one
of the processes P62, P63 is programmed, then t his process is perf orm ed i n
the case of warm as well as cold r estart. If t he process P62 neither P63 is
programmed, then process P0 is solved first after transfer to the RUN
mode.

10.5.1 Configuration Constants in the User Program
Configuration constants are automatically generated during compi lation
of the user program, and they f orm its non-separable part. T hey carry inf ormati on on the required PLC mode and i ts use. Constants can be set using
menus of the xPRO i ntegrat ed com pi l er environm ent bef ore t he com pi l ati on
itself.
Configur ation constants contain the f ollowing services:
type of restart after turning on of t he P LC power supply
This determ ines whether after turni ng on of the power supply, warm or
cold restart will be performed (see item 10.4.4). Cold restart is the default
setting.
t ime of issuing the f irst warning of threat of ex ceeding of the m axim um
allowed cycle time
If the cycle of processing the user program lasts longer t han the t im e de-
fined by this constant, PLC system services set the bit S 2.7 as a flag that
in processing of the program, the set ti me has been exc eeded in thi s cy-
cle, and at t he same t i m e the sof t er ror code i s set in t he system r egister
S34 and S48 to S51. Default set val ue is 150 ms.
time of guardi ng the maximum allowed cycle time
If the cycle of processing of the user program lasts longer than the
maxi mum allowed cycle time, PLC announces crit ical error of ex ceeding
the cycle time, blocks the outputs and interrupts cycling running of the
user program. This constant defines the longest possible time during
which the controlled object may remain without an action intervention.
The defaul t set value i s 250 ms, the recommended m aximum value is
500 ms.
determining of t he ext ent of backup of the user program in EEPROM
Defines whether the whole user program i s backed includi ng tables T or
whether the user program is backed without the tables T and tables T
remain in the ori ginal v ersion i n backed RAM (suit able i n cases of modi -
fication of the tables by the user program). Backing of the whole user
program i s the default setting.
number of backed registers R (remanent z one)
Setting of the number of backed registers R values of which will be
saved in the case of the PLC power supply failure, ensured by the
checking character , and retrieved in the c ase of warm restart of t he PLC.
Registers are saved star ting f rom register R0, state of the registers af ter

10.5.2 Software Co nfiguration
Software (sw) conf igurati on of inputs and output s describes the PLC set,

Another possibility of the sw configuration is declaration of the PLC special f unctions. Speci al functi on use standard-fit ted PLC inputs and outputs,
however thei r serv ici ng requir es more com pli cated shell algori thms or com plement ation of the basic technical equipment of the input and out put unit.
These servici ng algori thm s are real i zed by t he system , t hus serv ic ing by the

This enables the user to hav e the sw configurat ion creat ed exact ly acc ording the real tec hnical equi pment or creat e a basis for the user's own declaration of inputs, out puts, and funct ions of the PLC set.
If no sw configuration is entered in the user program, the program will be
solved only above the PLC scratchpad memory and the PLC inputs and
outputs will not be serviced. Binary outputs will remain blocked in this case
and analog outputs will remain set to zero.

In measurement of the signal period, these 2 bytes hav e the m eaning of

Control of the measurem ent mode is done by a program using t he i m age

If the bit Yn.0 = 0, m easurement of the signal peri od is perfor med at input DI0 of BM, i f t he bit Yn. 0 = 1, m easurem ent of t he phase shif t of signals

Physical output DO0 of BM can be used only f or indicati on of the f unction m ode.
In signal period (f requency) measurement, it is possible to measure the
signal withi n the frequency of about 1 Hz t o 1 k Hz . The measured number of
cycles of the clock signal then reaches values of 32767 to 33. The value
65535 signals exceedi ng of t he m easurement range (i t corresponds with the

signals
By reading from t he phy si c al address or writing to the physical address of
inputs and outputs, t he correspondi ng change of value i n i m age of i nputs or
outputs in the scrat c hpad memory does not happen!
In the case of physical r eading, val ue in image of inputs is correc ted in
the course of the cycl e loop, and usually this is faulty (however, it must t o be
taken into ac c ount).
In the case of phy sical writ ing, i t i s necessary to ensure correcti on in the
scratchpad by the user program, otherwise in the cycl e loop t he outputs will
be set according to the original v alue in the image of outputs.
Another possibility is to turn off servicing of PLC outputs in the software
confi gurati on i n the c om pil er at com pi l ati on of t he user program (i tem of t he
directiv e
#unit
) and servi ce the outputs ex clusiv ely by di rect writi ng using
the U operand and the physical address.
10.6 Testing of Input and Output Signals
For testing of input and output signals connected to the PLC, it suff ices
to create an empty program containing only sw confi guration of the t ested
PLC and instructi ons P0 and E0 which create an empt y basic process. Af terwards it is possible t o observe stat es of the connected inputs using debugging means of the dev elopm ent env i ronm ent and set arbit rary v al ues at
the PLC outputs. This very simple but very efficient procedure is recommended to be used bef ore debugging of one' s own user program as in this
way the whole route fr om input elem ents (end switches, ...) through inputs
and to the PLC scratchpad m em ory is v eri fi ed in adv ance, as well as backwards, from the scrat chpad memory t hrough outputs and to the acti on elements. Errors arisen fr om connecting of the PLC to the controlled object can
be remov ed in t his way, f indi ng of which i s usuall y m uch m ore c ompl icated
in the phase of debugging of t he c ontrol program.

11. Diagnostics and Removal of Faults
The Tecom at PLC di agnosti c system i s a part of t he standard sw and hw
equipment of the PLC's. It is active starting from turning on of the PLC
power supply and operates independentl y of the user. T he main funct ion is
ensuring of error-free and accurately defined function of the PLC in any
situation. The system continuousl y follows v itall y important parts and functions of the PLC and ensures serv icing of an error state i mm ediately in the
moment of i ts occurrence and informs about the faul t.
In the case a fault ari ses within the P LC, the di agnostic system must especially eliminate the possibility of origination of breakdown states in the
technology connec ted to the PLC.
Another task of the diagnostic system is to make easier remov al of the
arise fault to service workers or to t he user, r espect iv ely.
Besides basic functions, the diagnostic system notifi es the user of any
possible erroneous mani pulati ons or procedures at the PLC at tendance due
to which working with t he P LC bec omes easier and more eff icient.
11.1 Conditions for Proper Function of the Diagnostics
The basic condition for error-free function of the PLC and proper operation of it s diagnostics is proper functi ons of the power supply and of the
central unit.
After turning on of the supply, basic checking of the system kernel is
perform ed wit hin t he i nit i ali zat i on. I f an error of the E PROM or RA M system
memory is found, the diagnostic system cannot continue in its operation.
This state is signalled by lighting t he letter E or t on the display.

11.2 Indication of Errors
The central unit is equipped with t he main error stack whic h contains 8
last error codes announced by the diagnostics of the whole PLC and a l ocal
stack containi ng 8 last error codes announced by t he diagnostics of serv icing of inputs, outputs, and c ommunication t hr ough the serial channels.
Full er r or c ode in the main error stack is 4 bytes long. The first byte gives
the basic error code ( it deter m ines the gr oup of f aul ts), the f ol l owing 3 bytes
give close specification of the er r or .
Full er r or c ode in the local error stack is 2 bytes l ong. The first byte giv es
the basic error code (it determines the group of faults), the second byte
gives closer specif ication of the error .
Contents of bot h error stacks are av ai labl e from t he x PRO dev elopm ent
envi ronment. Codes of serious errors are shown on the display at the moment of their eval uation in t he form at:
E -label followed with t he full error code in hexadecimal form
80 - basic error code
09 00 00 - closer error specification
11.3 Serious Errors
In the case of the rise of a serious error, the di agnostic system blocks the
outputs fi rst, inter rupts executi on of the user progr am, and then i t identi fies
the arisen fault. The ful l error code i s shown on the display and stored i n the
main error stack.
Indicati on of such an error can be cancell ed by a comm and f rom t he superior system or by turning off and on of the PLC power supply.

Mouse on COM3, communication on COM1
Mouse on COM4, communication on COM2
Some programs (for example, xPRO) cannot communicate on a
channel which shares the same interrupt vector as the mouse

The problem occurs in programs operating i n protected m ode or under

In the xP RO program which oper ates in the protected mode from v er si on
2.1, PC serial channel equipped with an equi val ent of ci rcuit 16550 wit h
buff er stacks is a necessity. Am ong com muni cati on options i n the xP RO

new computers are standard-equipped with these circ uits. O lder com put-
ers can be either equi pped with an additi onal board with serial channels
(xPRO then com municates even on a PC with t he 386SX processor) or
select
the comm unication speed (the speed m ust be obvi ously reduced at the
PLC central unit as well). The selection UART 16550A must not be
checked. Reducti on of the communi cation speed makes sense in PC's
equipped with the proc essor 486DX or 486DX2 and better.
Some programs in the Windows environment cannot switch with suffi-
cient speed from transmission to recei ving. Thi s problem can be easily
solved by setting sufficient reply delay at the PLC c entral unit (see Article

12. Removal of Faults
Wi thin the guar antee period, repai rs may be perf ormed onl y by the producer's employ ee or by a servic e or ganization determi ned on the basis of an
agreement.
PLC's of the TC600 series are complex electronic devices fitted with
parts for printed mounting and parts sensitive to the electrostatic charge.
Therefor e the produc er recom m ends to per f orm post-guarant ee repai rs onl y
by exchangi ng the whole units. For local ization of t he fault, the PLC's are
standard-fitted with the diagnostic system. Repairs of the units are performed by the producer.
13. Maintenance
When general conditions for the installation are met, the PLC requires
minimum maintenance. Operations in which demounting of a part of the
PLC is necessary, are performed always with the PLC power supply, i nputs
and outputs turned off.
13.1 Demounting of the PLC Parts
The BM cov er is formed by the cover of the inputs and outputs board
and by the LED display cover. Cov er of the i nput s and outputs board can be
remov ed after unscrewing 4 fastening screw, the LED displ ay cover can be
removed after unscrewing of 2 fastening screws.
EM and EM/2 covers (inputs and outputs boards) can be rem oved af ter
unscrewing of 4 fastening screws.
The inputs and outputs board can be taken out after unscrewing of 4
fastening screws. In the BM, the board is interconnected with freely demountabl e insertion connection with the CP U boar d.
Optional piggybacks are placed on the BM CPU board. To m ake them
accessible, it is necessary to take out t he mounti ng unit form ed by the CP U
board, the shiel ding cov er and the inputs and outputs board. Aft er remov al
of the BM c overs and after unscrewing of 6 screws on the bottom side of the
BM trough, the unit c an be taken out by i ts shif t i ng to t he ri ght (t he shiel di ng
cover is inserted in 2 slots on the lef t side of t he B M trough).
Parts sensitive to the electrostatic charge are used at the
PLC units. Follow principles for working with these circ uits
in manipulati on with the units.
13.2 Checking of PE Connectors Interconnection
Resistance between an arbitrary metal part of the PLC and the main
protecti v e connect or of t he case in whic h the PLC i s plac ed, i s measured by
the meter of smal l resistances. Val ue of the resistanc e must be 0,1
13.3 Checking of the Power Supply
The PLC power supply is measured at connectors marked as M1 and
M2. The allowed vol tage tolerance is 24 V~
±20 %, 24 V- ±20 %.
13.4 Checking of Voltage of Binary Inputs
Voltage of binary inputs is m easured between t he com mon connector of
the group (COM) and c onnec tors of indiv idual inputs (DI).
The allowed v oltage t olerance f or closing of the input i s 15 V~
or 16 V- to 30 V-. A llowed v oltage tol er anc e for opening of the c ircuit is0 V~

13.5 Checking of Voltage of Binary Transistor Outputs
Voltage of binary transistor outputs is measured between connectors
UDO and GND of the relevant gr oup of outputs. Al lowed volt age range is
9.6 V- to 28.8 V - .
13.6 Battery Exchange
Exchangi ng of the battery (Panasonic CR2032 or a si mil ar lithium battery
of 3 V, 210 m Ah, 20 mm ) can be per f orm ed wit hout l osing of t he user program and set parameters in the foll owing way:
turn off the PLC and i nputs and outputs power supply
remove the BM cov er
disconnect jumper V1 (nex t to the batt er y )
take out the battery (on the upper edge of the CPU board)
insert a new battery
connect jumper V1
screw on the BM cover
When t he battery i s disconnected (jum per V1 i s disconnected), mem ory
of the user program and t he RTC c ir cui t are suppl ied for the peri od of about
5 minut es from t he bac k ing condenser.
Metal i nstr uments which could short - c ircuit the battery (for
example the tweezers, flat pi nc er s etc .) must not be used
to insert the new batt er y . Pay attent ion to correct polarity.
The recomm ended interv al of the battery exchange is 5 years. F or the
way of indi c ation of lower battery volt age see Article 4.2.
13.7 Fuse Exchange
The internal fuse of the voltage converter can be exchanged without

Parity is standardly switched on. It is switched off only the cases of
necessity when it is necessary to com muni cate ov er modem s, e.g., that do
not transmit parity. By switching parity off security of transmitted data is
decreased (for details see Serial communication of TECOMAT programmable logic controllers and TECOREG regulators, version 7 and higher,
