2. M ODULE DESCRIPTION
2.1. System Overview
The e.bloxx modules have been developed for the industrial and experimental testing technology, especially for the multi-channel measurement of electrical signals of thermal or mechanical quantities at test beds and test sites.
Picture 2.1 - e.bloxx A6-2CF
The e.bloxx A6-2CF, which is described in this manual, is a modular measuring system for the automation of industrial
test stands as well as for monitoring of assembly and production processes. This module is designed for the measurement of quantities such as strain, force, displacement, torque, weight and pressure simple and safe. The module is part of a whole product line of different e.bloxx.
Due to the modular design, flexible definition of solutions and the standardized interface, the module provides maximum freedom, thus leaving enough space for further testing concepts.
Standardized interfaces guarantee the integration of up to 127 modules into a single network.
With the e.gate module very high data rates via Profibus-DP and Ethernet can be realized. The customer-specific signal processing supplements the standard conditioning of the single e.bloxx modules.

2.4. Functional Overview
This manual describes the e.bloxx module A6-2CF, which is a 16-channel (real plus virtual variables) module.
The first channel always defines the analog input which is a bridge sensor input for 3-, 4-, 5- or 6-wire bridges, each one with 1V, 2.5V or 5V supply. The other channels can be used for digital I/O’s, to process the digital input which can be used for example as a trigger, to make arithmetical calculations or to process the measured value (scaling, run/hold, minimum/maximum envelope curve). The channels are defined in the configuration table of the Configuration Software ICP 100.
The values of each channel can be read out via the RS 485 bus.
2.5. Front-LED
The LEDs at the front of the e.bloxx module provides the following information:
Right LED LED green Module works well, no signal overflow, no communication error… LED red general error like signal overflow, broken sense leads LED red + short off period general error like signal overflow, broken sense leads + communication timeout LED green + short red flash Signal ok + communication timeout LED red fast flashing global error, no suitable firmware Left LED (DSP function) LED green No DSP failure LED red DSP failure Notice: The right LED will get red when the signal leaves the selected range and the error checking is activated
(see ICP 100 column Range/Error).
2.6. DC-Isolation

3. MOUNTING e.bloxx A6-2CF AND CONNECTING WIRES
3.1. Environmental Conditions
The e.bloxx A6-2CF is protected against water and dirt according IP 20. If required by the conditions of the operating site the modules have to be installed accordingly, e.g. in a water-resistant or waterproof case, compliant with the regulations of electrical engineering.
For the allowed ambient temperatures for the e.bloxx A6-2CF please see the technical specifications at the end of this manual.
3.2. Connection Technique
The wires are connected to the modules via screw-type terminals. The captive terminal screws are part of the terminal strips. All terminal strips are of plug-in type and can be detached from the modules.
Not more than 2 leads should be connected with one clamp. In this case both leads should have the same conductor cross section. For the precise clamping of stranded wire we recommend the use of wire-end ferrules.
Notice: Connecting wires respectively the plugging-in and –out of the terminal strip is only allowed with modules in
power-off status.
In order to prevent interference with sensors, signals and modules, shielded cables have to be used for the power supply, bus connection and signal lines.
We strongly recommend using a single screened cable each input signal. To use more signals in one cable could generate interacting influences.
Notice: For optimal performance the e.bloxx modules must be grounded properly. This is achieved by utilizing the
Ground/Earth screw on the back of each e.bloxx module. The screen of the sensor cable has to be grounded at the same potential.
3.3. Power Supply
Non-regulated DC voltage between +10 and +30 VDC is sufficient for the power supply of the modules. The input is protected against excess voltage and polarity connecting error. The power consumption remains approximately constant over the total voltage range, due to the integrated switching regulator.
Due to their low current consumption (max. 180 mA at 24 VDC) the modules can also be remotely supplied via longer lines. Several modules can be supplied in parallel within the permissible voltage range and drop in the lines. If required, the supply lines together with the bus line may be incorporated in one cable.
In order not to overload the module power supply needlessly and to avoid unnecessary line troubles, a separate power supply is recommended for sensors with a large current drain.
The distribution voltage for the e.bloxx A6-2CF has to be protected by a fuse with maximum 1 A (inert). The modules have an internal fuse (reversible) for protection against excess voltage, excess current and wrong polarity.

Notice: It depends on the power supply unit and its noise and internal grounding issues whether it is helpful to
connect earth of the power supply unit with ground/earth of the e.bloxx module.
Picture 3.1. - Power Supply of the e.bloxx A6-2CF
3.4. Bus Connection
Only the connection of the e.bloxx A6-2CF to the bus is described in here. A detailed description of the bus and the communication of the modules can be found in the Communication Guide of the e.bloxx modules.
The e.bloxx A6-2CF have an RS 485 bus interface for connection to the serial fieldbus. The bus has to be terminated on both sides with characteristic impedance. The maximum line length depends on the transmission speed (refer to the Communication Guide for details) and can never be higher than 1.2 km per bus segment or 4.8 km via a physical bus string by using 3 repeaters. A maximum of 32 devices are possible at each bus segment and up to 127 devices via a physical bus string.
Wiring In general, the e.bloxx A6-2CF is connected to the bus by connecting both signal leads A and B of the incoming bus
cable and A' and B' of the outgoing bus cable together to one terminal on the module (Picture 3.2). Alternatively, the bus can also be connected by a "stub cable" (Picture 3.3). This guarantees that the bus connection to other modules remains in place, even if one module has to be exchanged, due to the removable terminal strip.

Picture 3.3. - Bus Connection of an e.bloxx A6-2CF to the RS 485 fieldbus via Stub Cable
The stub-cable should be as short as possible, not longer than 30 cm.
Notice: The terminal designations A and B of all modules of the e.bloxx series are exchanged compared with the
PROFIBUS-definitions. Consequently, in multi-vendor systems the bus lines A and B have to be exchanged when connecting them to the e.bloxx modules.
Bus Structure The bus structure is a line structure where each bus segment will be terminated with characteristic impedance on both
ends. Branches can be set up by means of a bi-directional signal amplifier, so-called repeaters. Other types of branches are not permitted (no tree topology). The max. stub-length to a user must not exceed 30 cm. The following pictures show a few examples of possible bus topology structures. The meanings of the symbols are as
follows:

Picture 3.7. - e.bloxx A6-2CF connected to e.gate
* ... If e.bloxx A6-2CF are used together with an e.gate, which is used to collect data of all connected e.bloxx modules
and processes them for fast transmission via the further network, a bus termination must be connected to the last e.bloxx in each bus line.
Bus Connection to PC
The bus interface of the e.bloxx A6-2CF is based on the RS 485 standard. Since most hosts are "only" equipped with RS 232 interfaces, an interface converter or a plug-in board with RS 485 drivers is required for conversion purposes.
Gantner Instruments Test & Measurement GMBH offers a compact interface converter, called ISK 200, with an inte-grated power supply and automatic baud rate detection. The power supply, bus connection and a separate 24 VDC-output are DC-isolated. Therefore, the interface converter ISK 200 is also applicable as a power supply for remote
applications. Additionally, the interface converter ISK 200 features the option of connecting the required bus termination via a switch. The converter is designed to be used as a desk device.
Another module IRK 100 from Gantner Instruments Test & Measurement GMBH is available which may be used as an RS 485 repeater or RS 485/RS 232 converter. The baud rate can be adjusted at the IRK 100. Also, for this module the required bus termination may be connected with a switch. The Repeater/ Converter IRK 100 has a snap-on mounting mechanism for the installation on standard profile rails (DIN rail) 35 mm according to DIN EN 50022.

Bus Connection to Profibus-DP
For the connection of the bus cable and bus interface to a PC 9-channel D-subminiature plugs and sockets can be used. The pin assignment for the RS 485 connection according to PROFIBUS is given in Table 3.1.
Table 3.1. - Pin Assignment D-Subminiature Plug According to PROFIBUS
The signal leads A and B (and Shield) are mandatory for a (shielded) connection. Additional signal leads may be installed if required.
Notice: Due to the fact that the RS 485 interface is used for different protocols, in case of using Profibus-DP the
leads A and B has to be crossed.
Bus Termination at the e.bloxx A6-2CF
In order to avoid signal reflections on the bus, each bus segment has to be terminated at its physical beginning and at its end with the characteristic impedance. A terminating resistor is installed between the bus leads A and B for this
purpose. In addition, the bus lead A is connected via a pull-up resistor to potential (VP) and the bus lead B is connected via a pull-down resistor to ground (DataGround). These resistors provide a defined quiescent potential in case there is no data transmission on the bus. This quiescent potential is level high.
The e.bloxx A6-2CF has these bus termination resistors built in. They can be connect to the bus by plugging the Bus Termination Plug IBT 100, which is available as accessory, into the rapid bus link plug on the front side of the module. Instead of the bus termination plug IBT 100, also separate jumpers may be used for the bus termination. In this case, it is mandatory that the jumper clips are installed as indicated below, and that the bus leads or the bus termination are not short-circuited by mistake.
