Communication

Note!

A 15 V DC supply voltage (+15 V at terminal 15 connected to the meter bus connection terminal

3)can be used at the WMZ connection of TROVIS 5476 Controller when the red jumper on the back of the controller is located pointing towards the edge of the controller (Fig. 8). Otherwise, the meter bus module in the heat meter is supplied. Furthermore, the heat meter is galvanically connected with controller input side (pulse and current input at terminal 15) resulting it being connected to the Modbus interface as well which can lead to the communication coming to a standstill.

9.4.1 Activating the meter bus

To successfully transfer data from the heat meter to the controller, the heat meter must use a standardized protocol in accordance with EN 1434-3. It is not possible to make a general state- ment about which specific data can be accessed in each meter. For details on the different meter makes, refer to the technical documentation TV-SK 6311. All necessary function block parame- ters to set up the communication with heat or water meters are available in function block FB 29. The meter bus address, the model code and the reading mode must be specified for the heat meters WMZ1 to WMZ3.

A meter bus address must be unique and correspond with the address preset in the WMZ. If the preset meter bus address is unknown, a single heat meter connected to the controller can be as- signed the meter bus address 254. The address 255 deactivates the communication with the re- spective WMZ. The model code to be set for the heat meter can be found in TV-SK 6311. In gen- eral, the default setting of 1434 can be used for most devices. The meters can be read either au- tomatically every 24 hours (approx.), continuously or when the coils (= Modbus data points) as- signed to the heat meters WMZ1 to WMZ3 are overwritten with the value 1 via the system bus interface.

9.4.2 Flow rate and/or capacity limitation via meter bus

Similar to the flow rate limitation based on a standardized 0/4 to 20 mA signal, the update rate of the measured variable, flow rate and/or capacity, must be smaller than 5 seconds in meter bus operation to carry out a proper limitation. Refer to the technical documentation TV-SK 6311

5476 specifications

The Samson 5476 is a high-performance microphone designed for professional audio applications, offering exceptional quality and versatility for various recording environments. Known for its robust build and advanced features, the 5476 is a reliable choice for musicians, broadcasters, and sound engineers.

One of the standout characteristics of the Samson 5476 is its cardioid polar pattern, which effectively isolates the sound source while minimizing background noise. This feature is especially beneficial in live performance settings or during studio recordings where external noise can be a challenge. The microphone’s frequency response ranges from 20 Hz to 20 kHz, making it suitable for capturing a wide variety of sound sources, from deep bass notes to crisp high frequencies.

The 5476 incorporates a dynamic transducer that enhances its durability and reliability, ensuring it can withstand the rigors of frequent use. The built-in shock mount system further reduces handling noise and vibrations, allowing for clearer audio capture. Additionally, the microphone is equipped with a built-in pop filter, which mitigates plosive sounds that can occur during vocal recordings.

This microphone also features a low impedance output, ensuring compatibility with a wide range of mixing consoles and recording interfaces. Users can easily connect the 5476 to XLR inputs, making it straightforward to integrate into any professional audio setup. The microphone’s high output level ensures excellent signal integrity, providing clean and precise audio reproduction.

Another notable technology in the Samson 5476 is its advanced capsule design, which helps to enhance the microphone's sensitivity and transient response. This results in natural-sounding audio, whether it’s used for vocals, instruments, or ambient sounds. The microphone’s construction also includes a durable metal body that can withstand the wear and tear of live performances and frequent handling.

In summary, the Samson 5476 is a versatile and reliable microphone that combines advanced technology with practical features suited for both studio and live environments. Its cardioid pattern, dynamic transducer, low impedance output, and robust build make it a valuable tool for any audio professional looking to achieve high-quality recordings. Whether for vocals, instruments, or broadcasting, the Samson 5476 delivers consistent performance and exceptional sound quality, making it a top choice in its class.
