Figure 1.1.1 Basic connection example for basic module CP-100
Notes for connection:
1. Groups of relay outputs (DI0÷2 and DI3÷5) can switch the circuits supplied from various sources.
The groups are isolated by isolation corresponding to safe circuit isolation.
2. The optional functions of DI/AI inputs are set from the programming environment, some
connection examples are shown in the following chapters.
3. The TCL2 bus is fixed terminated on the basic module and it always has to be at the end of the
bus line (refer to chapter 3.2).
. The power supply of the module, the interfaces TCL2, CIB and CH1 have common signal ground,
the GND terminal (terminal A3). This terminal is connected to the common DI/AI terminal
(terminal B1).
5. The analog inputs AI0÷AI3 are configured as inputs with common negative terminal GND.

Tecomat Foxtrot – system design 5/32
1.1.1. Power supply of basi module CP-1004
For proper functioning, the module requires smoothed direct current supply voltage 2 VDC (in case of
power supply backup by batteries, the system can be supplied by a 27.2 VDC source - we recommend to
use the PS-50/27 power supply source). The maximum power consumption of the system (under full load
- closing of relay inputs, with an additional submodule fitted and with active communication) is 8 W.
The module power supply is galvanically connected with the inputs DI0 ÷ DI7, the CH1 communication
interface, the CIB1 interface and the TCL2 system channel. Also in case the CH2 channel is fitted with a
submodule with galvanically non-isolated I/O circuits, these circuits are galvanically connected with the
power supply of the system. The common pole is the GND terminal (terminals A3, terminals B1).
NOTE
When applying the system, the common pole (galvanic connection) of the above-mentioned I/O parts of
the module should be taken in account – especially in case of supplying from more positions, more power
supply sources or risk of occurrence of ground loops.
SELV:
If the power supply source fulfils the parameters of SELV sources according to ČSN 33 2000- - 1, than all
I/O circuits of the system fulfil the SELV requirements. Also in cases when the relay outputs switch the
low voltage circuits (isolation of relay outputs from the internal circuits of the system is kV AC).
Sour e parameters:
Usually, most of power supply sources with 2 V= output stabilised voltage comply for suit. An non-
stabilised power supply source can also be used, but attention should be paid to the output voltage (for a
power supply source with a high output, the output voltage might exceed the permissible value.
Sour e output determination:
A source with an output of min. 15W is optimal to supply an individual control system. If further circuits
are supplied from this source, its output has to be increased proportionally. In case a source with non-
stabilised output is used, the permissible range of the supply voltage should be followed, especially in
cases when power supply sources with a high excess output are used.
Power supply prote tion:
The power supply input (terminal A ) is not protected by an internal fuse. We recommend using a front-
end external fuse before the modules power supply with a recommended nominal value of T500L250V.
In reasing resistan e of module power supply sources:
To ensure a trouble-free operation also in exceptional situations (thunder strokes, generally bad condition
of the distribution network or effects of close of power devices having negative effects to the distribution
network), we recommend using elements ensuring the resistance of the sources against unfavourable
effects of the environment. Detailed information on methods how to increase the reliability can be found
in the documentation TXV 001 08, chapter 2.

Besides the function of ordinary inputs, the binary inputs DI0, DI1 (counter 1) and DI2, DI3 (counter 2)
can be set to one of special functions that allow the connection of an incremental position scanner,
application of fast counters, period and phase shift measurement (e.g. for generator phasing), etc. The
functions are described in detail in the manual Programmable controllers Tecomat Foxtrot, TXV xxx xx,

1.1.3. Communi ation interfa e CH1 of basi module CP-1004, interfa e RS-232
The CP-100 basic module is fitted with asynchronous serial channels (CH1, CH2), the CIB1 interface, the
TCL2 system channel and the ETHERNET interface. Each serial channel as well as the logic data channel
LCH (one Ethernet interface can realize up to four LCHs) can be set to one of the communication modes
and realize various networks and interconnections. Any of the channels in the PC mode can be used for
PLC programming, but always one at a time!
The serial interface of the CH1 central unit is fitted with a fixed terminal board. A view of the terminal
board (with the standard working position of the PLC on the switchgear panel) is on Figure 1.1.3.1.

Notes for connection:
1. The signal ground GND of the interface is common for module supply, the CIB and TCL2
buses (it is also common for the negative common terminal of the DI/AI inputs).
2. The RTS signal is the control signal (output), which is used by some devices (interface
converters, etc.). The use of the signal is described in the manual Serial communication of
programmable logic controllers Tecomat TXV 001 06.
1.1.4. Communi ation interfa e CH2, use of optional submodules
The CH2 communication interface is led-out to the C terminal board (refer to Figure 1.1. .1) and
standardly; it is not fitted by any module. According the interface required (RS232, RS 85, CAN, M-bus
etc.), the customer chooses the corresponding submodule and installs it to the prepared position inside
the module (the procedure of submodule installation is described in the manual Programmable logic

MR-0104 - interfa e RS-232, with galvani isolation
The MR-010 submodule is used for the transmission of the TTL signals of the serial interface to the RS-
232 interface, including galvanic isolation. This interfaces is designed only for the connections of two
participants (point-to-point connection). It can be advantageously used for example to realize a
connection of a TECOMAT PLC with a PC for short distances (to 15 metres). The galvanic isolation of the
serial interface is ensured by a built-in converter and no external power supply is required. Detailed
information on the submodule, its internal connection and setup are described in the documentation TXV
101 0 .

The MR-011 submodule is used for the transmission of the TTL signals of the serial interface to the RS-
85 interface with galvanic isolation. This interface works in the semi-duplex mode and allows multidrop
interconnection of participants. For proper functioning, the communication line has to be terminated
correctly (see the following paragraphs). The galvanic isolation of the serial interface is ensured by a built-
in converter and no external power supply is required. Detailed information on the submodule, its internal
connection and setup are described in the documentation TXV 101 0 .

The MR-012 is used for the transmission of the TTL signals of the serial interface to the RS- 22 with
galvanic isolation. The interface allows the connection of two co-operating devices (point-point). Each line
(RxD as well as TxD) has to be terminated at the line end by terminators 120 Ohm.
The galvanic isolation of the serial interface is ensured by a built-in converter and no external power
supply is required. Detailed information on the submodule, its internal connection and setup are described

MR-0152 - interfa e PROFIBUS DP, with galvani isolation
The MR-0152 submodule allows the connection of PLC TECOMAT Foxtrot to the PROFIBUS DP network as
a slave station (subordinated) with a transmission rate of up to 12 MBd. It can be used in the DPS mode.
Since the physical interface of the PROFIBUS bus corresponds to the RS- 85 standard, the connection of
the connector of the serial channel is identical as with the fitted MR-011 submodule (refer to Table
1.1.3.2) including the possibility of termination.

1.1.5. Interfa e ETHERNET PLC Foxtrot (interfa es, ables)
The central module is standardly fitted with the Ethernet interface, 10/100 Mbit, RJ- 5 connector, refer to
chapter 1.1.5.1. Each Ethernet physical interface (i.e. one physical connection to the PLC) can realize up
to logic data channels (labelled as LCH1 to LCH ), which can be set to several modes and which allow
various system interconnection (further information refer to TXV xxx xx) and they are fully independent
from the other PLC communication interfaces (with the exception of system services in the PC+ mode,
which can be active at one moment only on one of the communication channels (physical as well as
logic).
1.1.5.1. Physi al interfa e ETHERNET PLC Foxtrot
The Ethernet interface is fitted with the standard RJ- 5 connector with standard signal distribution. The
connector is ready to be used with common UTP patch cables (for cable connection refer to chapter
1.1.5.2).

1.1.5.2. Conne tion of dire t and rossed ETHERNET UTP ables
The TP (twisted pair) connecting cables are either direct connecting cables (UTP patch cables) or crossed
cables.
The dire t TP able is the most commonly used cable designed primarily for connection HUB - terminal
(PC network card, PLC Foxtrot, etc.). It is standardly produced and available. The cable is fitted by the RJ-
5 connectors on both ends (8 pins). Only signals are functional (for commonly used 10Base-T
interfaces), the other conductors are not used (outlined by dashed lines on Figure 1.1.5.1).
A twisted pair cable has to be used (a phone line non-twisted cable cannot be used!) and one twisted pair
has always to be used for one data flow direction. For Ethernet cables, the colour coding TIA568B for
conductors in the cable is standardized and most frequently used, see table 1.1.5.1 (for direct cable).
The data UTP cables (non-shielded) and STP cables (shielded - the shielding is not connected on the
PLC side) are produced in several categories, numbered by 3 to 6. For 10/100 Mbit Ethernet (10Base-T),
any of the categories can be used, but at least the category 5 is recommended.
The basic product range of direct cables is supplied under the order number TXN 102 05.xx (the numbers
behind the point specify the cable length according to the product line - see the TC700 catalogue). The
maximum length of the TP cable is limited to 100 metres.

Crossed ables are used for direct connection of two equivalent devices (e.g. HUB - HUB (without
the uplink port on HUBs), Foxtrot - PC, Foxtrot - Foxtrot). They are not commonly available and they have
to be ordered with an expressed request for a crossed cable. The cable is fitted by the RJ- 5 connectors
on both ends (8 pins).
Only signals are functional (for commonly used 10Base-T interfaces), the other conductors are not
used (outlined by dashed lines on Figure 1.1.5.2). A cable with twisted pairs has to be used (a non-
twisted phone line cable must not be used!) and one twisted pair has to always be used for one data flow
direction.
The basic product line of crossed cables is supplied under the order number TXN 102 06.xx (the numbers
behind the point specify the cable length according to the product line - see the TC700 catalogue).

1.1.5.3. Re ommended UTP (FTP) ables for ETHERNET
TP cables (twisted pair) can be used as non-shielded (UTP) or shielded (FTP). The FTP shielded cables
can be very well used also for RS- 85 distribution (see chapter 1.1.3).
UTP cables, recommended types:
PCEY x2x0,5 (PCEY x2x0,6), manufacturer VUKI a. s. (distributor ISOKAB s.r.o.)
UTP data cable – class 5, manufacturer KABLO ELEKTRO, a. s. Vrchlabí
UTP Cat. 5, manufacturer PRAKAB
FTP cables, recommended types:
PCEHY x2x0,5 (PCEHY x2x0,6), manufacturer VUKI a. s. (distributor ISOKAB s.r.o.), refer to chapter
3.6.2.
FTP data cable – class 5, manufacturer KABLO ELEKTRO, a. s. Vrchlabí
UNITRONIC EtherLine-H CAT. 5, manufacturer LAPP KABEL
FTP Cat. 5, manufacturer PRAKAB
1.1.5.4. Prin iples of installation for ETHERNET distribution
General prin iples for installation of UTP ables:
When installing cables, sharp bends must be avoided. The cable should not be broken in corners, the
manufacturer specifies a minimum bending radius for each cable type – typically, the bending radius is six
times the diameter of the cable as minimum. Do nod bend the cable more than 90 degrees.
The cables must not be exposed to mechanical pressures. When drawing cables through holes or bars,
the permissible tensile strength must not be exceeded. Pulling the cables by excessive power more than
10 kg causes their damage by expansion of their twisting, which leads to failures (a higher error rate)!
The cables have to be mechanically protected, do not tense them, they should be left free. Also frequent
movements damage the cables.
If these principals of cable laying are not followed, data transmission could be slowed down and the cable
line could be interrupted. With respect to high frequencies, yet a small change to the geometrical
arrangement of the wires in the cable can cause data throughput problems (even if the cable can be
ohmicly in good order). The transitions of the cable to the connector are especially sensitive to mechanical
damage. In such cases, the cable can be protected from forced bending by axial tension.

For outdoor distribution, the cables should be laid into metal conduits with good ground connection and
overvoltage protection should be fitted on both ends of the cable (common for TP distribution of
computer networks). In case of a higher interference risk, paralleling, etc., shielded FTP cables are
recommended (STP, see chapter 1.1.5.3) together with active network elements (HUB, switch, etc.) with
the cable shielding connected to the safety grounding (only on one side of the cable!!).
Paralleling with other ables:
It is not permissible to lay the UTP cables close to power lines. If the minimum distance of (0.15 m)
cannot be followed, especially if the distribution is done in bars and plastic conduits, shielding channels
have to be used for computer distribution lines (conduits made from zinc-coated sheet metal). These
conduits have to be well connected within the whole distribution system to be conductive and they have
to be connected with the ground conductor of the power lines. The UTP cables have to be in a sufficient
distance (50 mm) from any part of the low voltage circuits (230 VAC).

The following diagram illustrates the possibilities of connections system - HUB according to the HUB
female connector used (i.e. normal female connector - downlink, or connecting female connectors used
primarily for the connections of HUBs into a cascade - uplink. Based on the type of connections, either
direct (normal) or crossed cables have to be used. The diagram shows the connections of HUBs using the
uplink female connector on one of the HUBs (than, we use a direct cable), or using of normal female
connectors (downlink) for both HUBs (than, we use a crossed cable).

ATTENTION! Some HUBs commonly available have one of the standard female connectors (downlink)
common with the connecting female connector (UPLINK). In case we use the female connector UPLINK to
interconnect HUBs among each other, than we cannot use the corresponding standard female connector
(and vice versa). For more details see the documentation of the HUB used.

The interconnection of two Foxtrot systems by a serial channel with the RS- 85 interface is illustrated on
Figure 1.1.6.2. The interconnection assumes two systems and thus the bus termination is realized on both
sides. In case of interconnection of more systems, the termination (terminals BT+ and BT-) will be
connected only on the end systems connected to the bus. Further parameters (conductors, principals of
installation) are valid according to the previous paragraphs relating to RS- 85.

want or cannot use the ETHERNET interface), we can use the RS-232 interface and the cable connected

Module XL-0471 – onne tion example for Foxtrot, interfa e RS-485
If we require an interconnection of the Foxtrot communication channels (e.g. realization of a PLC network
with the RS- 85 interface) or if we want to connect another device to the communication interface of the
Foxtrot system or if we require increasing overvoltage resistance, we can us the XL-0 71 module. The
module has a hub of the RS- 85 interface, the through connection (terminal boards A and B) go directly
through the module and the branch (terminal board C) is protected against overvoltage (arresters,
transil).
An example of connection of the module can be seen on Figure 1.1.6.5. At the same time, the module
allows direct connection of cable shielding. The shielding of through branches is interconnected and
brought to the G1 terminal (e.g. for a through cable, the shielding does not need to be grounded on the
module, the shielding of the branch is connected to the G2 terminal, to which also the overvoltage
protection is connected and its connection to the switchgear grounding is assumed (grounding for work).
