  • Page 22: The Basic Concept

    BL20 Philosophy The basic concept BL20 is a modular I/O system for use in industrial automation. It connects the sensors and actuators in the field with the higher-level master. BL20 offers modules for practically all applications: Digital input and output modules Analog input and output modules Technology modules (counters, RS232 interface...) A complete BL20 station counts as one station on the bus and therefore occupies one fieldbus address...

  • Page 23: Bl20 Components

    BL20 components BL20 components For a detailed explanation of the individual BL20 components, please refer to chapter 2 and chapter 4. The "Appendix" to this manual contains (amongst others) a list of all BL20 components and the assignment of electronics modules to base modules. 2.2.1 Gateways The gateway connects the fieldbus to the I/O modules.

  • Page 24: Power Distribution Modules

    BL20 Philosophy 2.2.2 Power distribution modules The power supply for gateways and I/O modules is fed to the power distribution modules; therefore, it is not necessary to supply each individual module with a separate voltage. Figure 2-2: Power distribution module 2.2.3 Electronics modules Electronics modules contain the functions of the BL20 modules (power distribution modules, digital...

  • Page 25: Base Modules

    BL20 components Figure 2-4: Electronics module in block design 2.2.4 Base modules The field wiring is connected to the base modules. These are constructed as terminals in block and slice designs and are available in the following variations with either tension clamp or screw connections: 2- /3-wire (2-channel), 4-wire (2-channel) and 4x 2-/3-wire (4-channel).

  • Page 26: Bl20 Eco

    BL20 Philosophy Figure 2-7: Base module in block design 2.2.5 BL20 ECO With the BL20 ECO modules the electronics and connection technology is integrated into a single housing. Thus, the selection of a base module is unnecessary. Within a station the ECO modules can be combined with the modules with separate electronics/connection technology, provided that the base modules feature tension spring connections.

  • Page 27: End Plate

    BL20 components 2.2.6 End plate An end plate on the right-hand side physically completes the BL20 station. An end bracket mounted into the end plate ensures that the BL20 station remains secure on the mounting rail even when subjected to vibration. Figure 2-9: end Plate 2.2.7...

  • Page 28: Jumpers

    BL20 Philosophy 2.2.8 Jumpers Jumpers (QVRs) are used to bridge a connection level of a 4-wire base module. They can be used to connect potentials in relay modules (bridging the relay roots); thus considerably reducing the amount of wiring. Figure 2-11: Jumpers 2.2.9 Shield connection (gateway)

  • Page 29: Marking Material

    BL20 components 2.2.10 Marking material Labels: for labeling BL20 electronics modules. Markers: for colored identification of connection levels of BL20 base modules. Dekafix connector markers: for numbering the mounting slots on BL20 base modules. Figure 2-13: Marking material 2.2.11 Shield connection, 2-pole for analog modules The 2-pole shield connection can be used to connect signal-cable shielding to the base modules of analog input and output modules.

  • Page 46: Power Feeding Modules

    Power distribution modules Power Feeding modules Power Feeding modules distribute the required 24 V DC or 120/230 V AC field voltage to the I/O modules. They are necessary when groups of modules with different potentials are planned within a BL20 station, or if the rated supply voltage cannot be guaranteed.

    Relay modules General BL20 relay modules (R) receive output values from the gateway via the internal module bus. The modules convert these values and transmit the corresponding circuit state for each channel to the field level via the base modules. Relay modules are suitable for solenoid valves, DC contactors and signal lamps in the nominal-load voltage range 24 V DC / V AC to 230 V AC.

    Module BL20-1CNT-24VDC Period duration measurement Definition In this operating mode the counter module measures the precise time between two rising edges of the counter signal in ms by counting the pulses of an exact internal quartz crystal reference frequency (1 MHz). An averaging operation can be carried out over 1 to 1 000 periods. It is defined by the integration time parameter or by the LOAD_INTTIME status bit in the control interface/process output.

    Technology Modules 10.1.6 Functions and explanations Software gate and hardware gate A release signal is required in order to start counting/measuring. The counter module controls the starting and stopping of the counting/measuring operation by means of so-called "gates". A software gate and a hardware gate are provided for implementing this control both via the software (process output/control interface) and via a physical output: The software gate initiates the release via the SW_GATE control bit.
