CAS Provides Affordable Data Acquisition and Recording

Novus FieldLogger RTU 8-Channel Data Logger
CHESTERLAND OH—January 9, 2012

CAS DataLoggers has teamed with Novus Automation to provide customers with the newest solution for flexible, affordable data acquisition and supervision. The bestselling Novus FieldLogger RTU 8-Channel Universal Input Data Logger is a microprocessor-based data acquisition and recorder designed to handle any analog input and operates either as an RTU linked to a PC for online recording and supervision, or as a stand-alone data logger with real-time clock and graph capabilities. This low-cost logger is widely used as a Modbus RTU input device as part of a SCADA system to transmit channel data using Modbus protocol. With 8 universal channels accepting different input sensors simultaneously, these high-speed industrial dataloggers have lots of available memory and many connectivity options along with expansion modules and wireless communication accessories.

The datalogger is DIN rail compatible and includes a 35mm rail mounting in an ABS enclosure. Configuration is retained on the logger in non-volatile memory, and configuration and data retrieval are managed using a PC along with the included configuration utility software. The Novus FieldLogger also features an RS485 interface allowing communication up to 1.6 miles (1 Km). For users without a RS485 port on their PC, Novus also manufactures an easy-to-use USB-RS485/RS422 converter, transforming an ordinary USB port into a fully-functional RS485 interface.

The Novus FieldLogger features 8 universal analog inputs supporting several types of thermocouples as well as Pt100, mA, mV and higher voltages by applying external resistor dividers. The logger is also capable of performing mathematical operations in the input channels. Additionally, the FieldLogger has one digital input for remote start/stop and 2 alarm relay channels which can be activated when any channel enters a programmed alarm condition; these relays can also be used as digital outputs. The logger also provides internal cold junction compensation for thermocouples, enabling high-accuracy measurements. Recording at a working temperature of 32 to 130°F (0 to 55°C), the new datalogger also features an internal resolution of 20000 counts, linearity of better than 0.05% of FS, and can scan 8 channels in 0.5s.

FREE FieldChart configuration utility software is included and is downloadable from the manufacturer website. FieldChart is a Windows compatible software which performs the communication and data treatment for the FieldLogger recorder and Novus controllers with RS485. This easy-to-use intuitive system saves users the hassle of previous training. The main module collects data to the PC, displays the data in both digital and graphic formats in batches or in real time, and provides trend and historical views. It can zoom in and out, superimpose or link graphs in one screen, print graphs or lists, and export to spreadsheets or word processors. The practical configurator module performs the setup of the FieldLogger parameters and also allows users to check general status. In addition to its standard use as a Modbus RTU, for online reading and recording (history), the included Microsoft Windows FieldChart software also reads and records a graph for a 10-minute period. Users needing more in-depth data analysis can upgrade to the full FieldChart analysis software to allow the Field Logger to form a complete data acquisition system.

With the power and versatility to handle analog and digital signals at high resolution and speed, the Novus FieldLogger is a cost-effective solution for customers’ data acquisition and temperature recording needs. Check out the Novus Fieldlogger product page here.

Totalizing with dataTaker DT8x Data Loggers

Utilizing dataTaker Intelligent Universal Input Dataloggers

CHESTERLAND OH—December 13, 2011

Systems integrators often receive requests for help with datalogging applications that require totalizing to get volume, event counts or the total energy produced or consumed. Using the internal channel variables and calculation capabilities of the dataTaker DT8x series of intelligent dataloggers, it is quite easy to capture cumulative totals as well as to total over a particular period of time such as a day, week or month. There are 2 types of signals that can be totalized: analog signals like a 4-20mA current loop from a device like a flow meter, and digital signals from a switch or pulse output meter. The technique to totalize each is slightly different.

When totalizing analog signals, a very common application involves reading a flow meter which provides a 4-20 mA output to display the instantaneous flow rate and then integrating this flow rate to get volume. dataTaker data loggers provide 2 built-in functions to automatically integrate measured values. The IB Data Manipulation function provides a simple 2 point integration by taking the average value calculated from the current sample and the previous sample and dividing by the time difference between the 2 samples. The INT Statistical function will sample the input at a rate determined by the statistical schedule and perform an integration using a trapezoidal approximation.

The main difference between these 2 techniques is how often the input is sampled to perform the integration. The IB function will only sample based on the main schedule rate, whereas the INT function samples at the statistical schedule rate. For example, if the main schedule was set for a 1-minute sample interval and the statistical schedule was set for a 10 second interval, the IB function would sample the input once every minute and integrate using just these 2 points while the INT function would sample every 10 seconds and return the sum of these 6 smaller integrations. While the INT function requires more resources and may not be appropriate for an application that requires low power, the advantage is obvious–it provides much better accuracy for situations where the flow could change rapidly–for example in a process machine that may be switching the flow on and off during different parts of the process cycle.

In either case, the function only provides the total over the sample interval, so it is necessary to use an internal variable to accumulate the total over a longer period of time. Using the += function provides a convenient way to do this. Simply pick a CV to use for the total, select the Assign to channel variable and then CV = CV + value, and you will now have a variable that contains the total value.

It’s also important to keep in mind the scaling with respect to these functions. Both functions work in units of seconds, so it may be necessary to adjust the scaling to get the returned value in the desired units. For example, if the desired units for the flow rate are in gallons per minute (GPM), then the value returned by either of the integration functions must be divided by 60 to convert from seconds to minutes to get the correct units.

In some cases all that is required is to accumulate the total since the start of the program, while other applications may require a daily, weekly or monthly total. In these cases, another schedule within the logger (in conjunction with an alarm if necessary) can be used to reset the total. For example, if only a daily total was required, a second schedule could be created to run once a day and within this schedule the CV containing the accumulated total could be set to 0.

For other reset intervals, the data logger also provides an internal channel for the day of the week (4ST) along with system variables for the day of the month (20SV) and day of the year (21SV). These can be used in an alarm statement to reset the channel variables containing the totalized data via the Action Command. Finally, it is also possible to use a manually triggered schedule to reset the counters. In this instance the schedule (triggered by an external switch or pushbutton) can contain the commands to reset the variables containing the accumulated total to zero.

Totalizing a device with a digital pulse signal output is easier than a sensor with an analog output. The dataTaker datalogger has 2 sets of counter inputs that can be used to count pulses. Any of the digital inputs 1D-8D (1D-4D for DT82 loggers) can be used as a low speed counter to measure pulses up to 25 hZ. Be aware, however, that these counters are not active if the logger is asleep, so they are not suitable for applications that require the lowest power consumption when the logger is allowed to sleep between samples.

If it is necessary to measure higher speed pulses, the loggers also provide 4 high speed counter inputs that can measure pulse frequencies up to 10 kHz. These counters can automatically accumulate the number of pulses, so that with the appropriate scaling they can provide a direct output of totalized flow. However, the counters are 32 bits wide, so it is possible for them to overflow and wrap back to zero. These counters also have a resetting mode whereby they are reset to zero after each time they are read. It is possible to combine the resetting mode with a channel variable that uses the += function to provides an accumulating counter in software. In this case, the counter is read, added to the totalized count that is contained in a variable, and then reset to zero to start the next count interval. Just like the analog counters, the digital counters can be reset by a schedule with an alarm command if necessary to periodically reset the total.
