March 24, 2016—Endress+Hauser releases the Memograph M RSG45 Data Manager, a compact device that can serve as a data acquisition system for small process control applications. The RSG45 acquires up to 14 discrete and 20 universal/HART analog inputs from process sensors, displays sensor data on its 7-inch multicolor TFT screen, records the data internally, performs math calculations and alarm checks, and transmits the data to a PC or any control system via Ethernet, RS232/485, Modbus, Profibus DP or PROFINET digital communication links. Data can also be stored to a device plugged into the USB or the SD port.
Inputs to the RSG45 include 4-20mA, 4-20mA with HART, voltage, RTD, thermocouple, pulse, frequency and current. The base unit can accommodate up to 14 discrete inputs, 2 analog outputs and 12 relay outputs. Up to five I/O cards can be added to the base unit, allowing up to 20 universal/HART analog inputs.
Data is stored in tamper-proof internal memory, on an SD card or on a USB stick—all of which fulfill the security requirements of FDA 21 CFR part 11. An integrated web server allows browser-based access to the unit via laptops, PCs, smartphones, tablets, handheld maintenance devices and remote systems.
The built-in Advanced Data Manager includes packages for mathematics, alarm functions, batch management, wastewater + RSB (rain spillway basin) applications, and energy calculations.
With the mathematics package, measured values of the inputs or the results of other math channels can be linked mathematically. Custom formulas with up to 200 characters can be created using a formula editor. The Telealarm function can activate relays in case of alarm conditions, and can also send emails or SMS messages to alert personnel of process alarms or other important process events.
Batch management software allows users to reliably record and visualize process data. User-definable or externally controlled analysis intervals can be configured for up to four batches simultaneously. Batches are assigned batch-specific values and the measured data, start, end and duration of every batch, along with the current batch status, are displayed on the device. At the end of the batch, a batch print-out is automatically sent to the device’s USB or network printer, or can be printed out on a connected PC.
The energy package allows users to calculate the mass and energy flow in water and steam applications on the basis of the flow, pressure, temperature or temperature difference input variables. Other energy calculations are also possible for glycol-based refrigerant media.
The RSG45 has a HART gateway function that allows direct access from PC configuration software to the field devices connected to the unit without the need for an additional HART modem or a loop interrupt. This allows
configuration of the field devices to be done easily and quickly from the control room. With this feature, detailed instrument health status is available as well. This helps simplify maintenance and troubleshooting.
The RSG45 is a panel-mounted device with an optional 316L stainless steel front panel and touchscreen. The stainless steel front, along with mounting the unit in a pressurized enclosure system, makes the standard device appropriate for use in potentially explosive atmospheres. Since the RSG45 is protected against contamination, it fulfills hygienic requirements in the food & beverage and the life sciences industries.
The RSG45 has UL and ATEX approvals, meets IEC 60529 and 61010-1 requirements for protection and safety, and is available in an ATEX Ex p hazardous area version.
