Detailed functionalities of the JUMO meroVIEW 108Q
Additional functions can be implemented via mathematical functions or ST code, such as calculating the total flow rate (volume).
Signal assignment via selectors
The input signals as well as all internal signals are available in so-called selectors (analog selector, digital selector) for further use within the device. The control signals for the outputs are also assigned via selectors, enabling flexible assignment of signals and functions.
USB interfaces
The device features a USB device interface (Micro-B socket on the rear), which is exclusively intended for connection to a PC for use with the setup program. In addition, a USB host interface (Type A socket) is available. On devices in formats 108 and 104, it is located on the rear, while on the smaller 116 format device it is located on the side. This interface is intended for connecting a USB flash drive to perform firmware updates, read out the data logger, and transfer device configurations.
RS485 interface
The RS485 interface is optionally available and supports the Modbus RTU protocol. It can be used in both master and slave operation.
Ethernet interface
The Ethernet interface (Modbus TCP) is optional and enables parallel communication with 2x master or 2x slave. It is used for integration into a company network, transfer of process values and communication with the setup program.
PROFINET interface
Optionally, the device can be equipped with a PROFINET interface to be integrated as an IO device into a PROFINET network. A GSD file (GSDML) is available for the programming system of the IO controller, describing the properties of the device. It should be noted that Ethernet standard services are not supported via the PROFINET interface. If the device is equipped with the PROFINET interface, neither the Ethernet nor the RS485 interface can be used.
Power supply
The device is available in two power supply variants: AC 110 to 240 V or AC/DC 24 V (see technical data).
Electrical connection
Electrical connection is carried out in a time-saving manner using removable spring-loaded terminals (Push-in technology).
Min/max function
When the min/max function is activated, both the minimum and maximum values of the display are stored and continuously updated. These values can be displayed separately or alternately with the current value. During alternating display (scrolling), the min/max symbol is active while either the minimum or maximum value is shown. The stored values can be reset via a binary signal to return to the current value.
Hold function
The hold function freezes the display value, meaning it remains displayed as long as the controlling binary signal is active.
Tare function
The tare function allows the display value to be set to zero, controlled by a binary signal (e.g. in weighing applications). The currently displayed value is added to the tare value each time. Another binary signal can reset the tare value to zero so that the current value is displayed again.
Limit value monitoring
The device is equipped with 8 limit value monitors, each with 8 configurable alarm functions. Any analog signal from a selector can be selected for monitoring, while the limit value can be an absolute value or dependent on another analog signal. Special functions include:
- switch-on/off delay
- wiper function
- alarm suppression during startup or parameter changes
- latching with acknowledgement
Limit value monitoring enables a wide range of alarm and limit functions.
Digital control signals
This function allows configuration of up to 8 digital control signals. The control signal can be formed by AND/OR/XOR linking of up to three selectable binary signals, or a single binary signal can be used as input and output as a pulse, delayed signal, wiper signal or edge-triggered signal. In the latter case, the rising or falling edge of the binary signal is detected and the output signal is activated for the duration of a sampling interval. The output signal can be inverted in all cases.
Timer
The device is equipped with 2 timers, which can be started via freely selectable digital signals or depending on an integrated tolerance band monitoring. Lead and lag times as well as a latching function with acknowledgement are also available.
This enables a wide range of functions such as time-controlled control processes or setpoint switching.
Service counter
The service counter can either count the number of switching operations of a binary signal or measure its operating time. Once the defined limit value is reached, a binary signal is activated which must be acknowledged. In addition, an operating hours counter records the device runtime.
Mathematics and logic function
The optional mathematics and logic function (type extension) allows analog or binary values to be linked. Up to four freely configurable formulas can be created using the setup program. The results are then available in the analog or digital selector for further use.
Structured text
With the "Structured Text" option (type extension), users can develop individual applications using PLC programming. The application is created using the ST editor within the setup program and is executed continuously on the device. Online debugging functions are available for testing and troubleshooting.
The setup program also allows creation of up to 100 custom texts that can be displayed on the device screen in four languages depending on the selected language.
Data logger
The data logger records 4 analog and 4 binary values. The recording interval can be set between 1 minute and 1 hour. Recording is based on a ring memory principle, overwriting older data when memory is full. At a 10-minute interval, data can be stored for approximately 2 years.
Data is exported via a USB stick in CSV format.
Real-time clock
The real-time clock provides the current date and time (timestamp for data logger and ST code).
Retain memory
The integrated retain memory ensures that specific data remains available even during power failure, including service data, counter and timer data, and ST code data.
Customizable user levels
Users can configure the device menu individually for maximum usability and optimal integration. Four menu levels with submenus are available and can be customized and secured against unauthorized access.
Setup program
The setup program is essential for commissioning and is available free of charge. It enables configuration, data management, and documentation, including wiring diagrams.
Startup: allows recording of process values during commissioning for up to 24 hours.
Online data: current process values are displayed in a separate window.
Firmware update
The device firmware can be updated easily using a USB stick; files are provided by the manufacturer as required.
