In “Transparent” mode, the device operates as a standard level converter, whereby signals at the interfaces (depending on the device: RS-485, RS-232, USB, M-Bus manager or Ethernet) are forwarded directly to the M-Bus terminals without processing.<\/span><\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”What do the FCB and FCB Toggle functions mean for M-Bus level converters\/splitters\/gateways?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n
The FCB bit is sent to the meter and changes its status after successful transmission. If the FCB bit does not change, the device prompts the meter to send the data again. With FCB Toggle, the device automatically takes over the change of the bit. <\/span><\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”What does the FCV function mean?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n
If a response telegram from a meter does not fit into a single RSP_UD telegram, the evaluation of the FCV bit can be activated. The simultaneous evaluation of the FCV bit and the FCB bit signals the correct reception of the RSP_UD telegram for the following telegram. <\/span><\/p>\nThe meter responds to the toggle of the FCB bit and the FCV bit with a multiple telegram. Meters that only send a single RSP_UD telegram ignore the multiple telegram and always transmit the same, single telegram. <\/span><\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”What does the SND_NKE function mean?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n

An occasionally flashing overload LED may indicate a reset or overload. A Blinking frequency at 5-second intervals indicates a short circuit or overload. It is recommended to check the loads on the M-Bus terminals. <\/span><\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”Why does the M-Bus meter have 4 terminal pairs?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n
The four terminal pairs on an M-Bus meter or a corresponding connection module primarily serve to make installation and wiring more flexible and clearer. They are usually connected in parallel and thus offer several equivalent connection points for the 2-wire M-Bus line. The four terminal pairs are therefore not separate Bus segments, but only offer several parallel Access points to the same M-Bus line. This simplifies installation and wiring, especially in larger or more complex systems, and provides more flexibility when connecting meters or Sensors. <\/span><\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”Which documents are included with the devices or are available?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n
The device is usually supplied with an operating manual.

In individual cases, problems may occur when communicating with meters that are not yet known. In this case, please contact our Support and specify the meter type used. We will check the problem and provide you with uncomplicated support, for example through a firmware update, to ensure compatibility. <\/span><\/p>\n[\/et_pb_accordion_item][et_pb_accordion_item title=”What does standard load mean for M-Bus?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n
The standard load for M-Bus refers to the electrical current that a connected participant device (e.g. a meter) draws from the bus. It indicates how much current a device consumes on the M-Bus. <\/span><\/p>\nDetails on standard load:<\/b> standard load equals 1.5 mA.<\/span><\/p>\nEach M-Bus device (e.g. a heat meter) consumes a certain number of standard loads, usually one or two. The maximum number of participants on an M-Bus manager depends directly on the number of supported standard loads. <\/span><\/p>\nExample:<\/b> A level converter MPW-64 is designed for 64 standard loads. If each meter draws 1 standard load (1.5 mA), 64 devices can be connected. If a device draws 2 standard loads (3 mA), only 32 devices are possible.<\/span><\/p>\nWhy is this important?<\/b> Knowledge of the standard load is crucial for the planning and design of an M-Bus system to ensure that:<\/span><\/p>\n\n- the manager is not overloaded,<\/span><\/li>\n
- all devices communicate reliably,<\/span><\/li>\n
- and the power supply via the bus remains stable.<\/span><\/li>\n<\/ul>\n

A standardized fieldbus system for the remote reading of consumption meters, such as water, gas, electricity or heat meters. It was developed specifically for use in building and energy technology. Communication takes place between meters and a central data collector, usually in a manager-subordinate system. The transmission medium is usually cable-bound (2-wire line), but there is also a wireless version (Wireless M-Bus). The system complies with the European standard EN 13757 and is energy efficient, scalable and widely used in smart metering Applications. <\/p>\n

An M-Bus splitter divides an existing M-Bus network into several Bus segments or expands it to connect several managers or remote meters without disrupting communication. It electrically isolates (to avoid interferences or ground loops), copies signals from an M-Bus manager to M-Bus device Bus segments without loss and enables parallel operation of several managers, such as energy suppliers and property management. Areas of application include the simultaneous request to the meter from meters by different systems (building management system and external billing service provider) or the expansion of large systems (splitters supply remote Bus segments). In addition, a splitter allows you to quickly switch to another manager if one manager fails. There are passive versions without amplification as well as active models with amplification and galvanic isolation as well as priority control. <\/p>\n

A lightweight network protocol for communication between devices, which is mainly used in the Internet of Things (IoT). It enables efficient data transmission with low resource consumption, even with a poor network connection. The protocol is based on the publisher-subscriber model (Pub\/Sub), in which devices publish messages to so-called topics or subscribe to them in order to receive them. MQTT uses TCP\/IP as the transport protocol and works by default on ports 1883 (unencrypted) and 8883 (with TLS\/SSL). The central intermediary is a broker (e.g. Mosquitto), which controls all messages. Devices (clients) send or receive messages that are organized into categories (topics), for example house\/living room\/temperature. Advantages of MQTT are the low overhead, the event-based data transmission and the support of Quality of Service (QoS) for reliable communication. Thanks to the support of MQTT, no M-Bus manager is required to access meter values, as all IP-based gateways and level converters are MQTT-compatible. <\/span><\/p>\n[\/et_pb_blurb][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"
