Endress+Hauser Introduces Memograph M RSG45 Data Manager

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 a 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. 

Data is stored in tamper-proof internal memory on an SD card or on a USB stick, which fulfill the security requirements of FDA 21 CFR part 11, according to the company. 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 send emails or SMS messages to alert personnel of process alarms or other important process events.

Batch management software allows users to 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 printout is automatically sent to the device’s USB or network printer, or can be printed out on a connected PC.
