Modules full of REST.

A RESTful API (Representational State Transfer Application Program Interface) to simplify development of web-based services is now available in Acromag’s BusWorks® NT series remote I/O modules. The NT I/O module system firmware embeds the API to support reading/writing of I/O data. Web services can use HTTP POST and GET requests to exchange information with the NT’s I/O server. This approach allows devices to easily and securely communicate with each other over the world-wide web along a common Ethernet interface. 

Applications for BusWorks NT Ethernet I/O modules include remote data acquisition, status monitoring, actuator control, predictive maintenance, energy management, and more. REST API is a very popular web interface method because it relies solely on the shared universal HTTP protocol standard on Ethernet. Developers can use XML, JSON, HTML, or other languages to build mobile app projects, IoT Internet of Things data interfaces, and more. The RESTful API is very fast and lightweight. It is also very cost-effective since developers can use the same API request across many environments without third-party tools.

NTE Ethernet I/O models have dual RJ45 ports and a webserver allowing remote system controllers to read or write data on connected sensors and actuators. Each I/O module offers up to 16 input or output channels for voltage, current, temperature, and relay control signals. Attaching up to three NTX expansion I/O modules can interface an additional 48 channels with a mix of I/O functions networked on a single IP address. “The NT series RESTful API provides a simple, secure way for web clients to exchange data with NT I/O module servers to monitor or control the status of remote equipment,” explains Robert Greenfield, Acromag’s Director of Business Development.

The NT2000 Series offers a broad variety of I/O signal processing options. Fifteen I/O configurations are available as either NTE Ethernet I/O or NTX expansion I/O models. Analog I/O models feature eight differential or sixteen single-ended inputs for monitoring current or voltage signals. Analog output modules drive eight channels of process current or voltage signals to control various field devices. Discrete I/O models provide 16 tandem input/output channels with either active high/low input and sinking/sourcing output. A six-channel mechanical relay output model is also available. For temperature monitoring, thermocouple and RTD input models support many sensor types, as well as resistance and millivolt ranges. More models will release over the coming months for additional I/O functions.

In addition to the new RESTful API, each module will also support OPC UA and MQTT interfaces plus three industrial Ethernet protocols (Modbus TCP, Ethernet/IP, PROFINET) which are selectable using any web browser to configure the network settings and I/O operation. The modules typically function as a network server, but also offer Acromag’s i2o® peer-to-peer communication technology to transfer data between modules directly or multicast without a host or master in between.

Acromag’s BusWorks® NT series remote I/O modules now offer a cost-effective solution for Industrial Internet of Things (IIoT) applications. The NT Ethernet I/O modules provide an OPC UA server and MQTT client in addition to the fieldbus protocol stacks (Modbus TCP/IP, Ethernet/IP, and PROFINET). This integrated IIoT functionality offers a standardized data exchange to simplify industrial communication in an increasingly complex environment. Applications for these high-performance Ethernet I/O modules include remote data acquisition, status monitoring, actuator control, predictive maintenance, energy management, and more.

The new OPC UA and MQTT support make data sharing and connecting to the cloud very easy and secure. Users can combine Ethernet protocols with IoT protocols for real time and IoT data transfer over the same network cable. An abstract data object model eliminates hassles with protocol details. The user application simply reads and writes data that is transparently fed into the IoT protocols and information models. Input, output and configuration data objects closely resemble fieldbus I/O tags to simplify data exchanges.

NTE Ethernet I/O models have dual RJ45 ports and a webserver for monitoring or controlling its I/O channels to interface sensors and actuators with system controllers. Each I/O module offers up to 16 input or output signals for voltage, current, temperature, and relay control signals. Connecting up to three NTX expansion I/O modules enables interfacing an additional 48 channels with a mix of I/O functions networked on a single IP address.

“With the addition of OPC UA and MQTT capabilities, NT Series Ethernet I/O modules make data from remote equipment available for sophisticated applications in the cloud or on edge gateways,” explains Robert Greenfield, Acromag’s Director of Business Development.

The NT2000 Series offers a broad variety of I/O signal processing options. Fifteen I/O configurations are available as either NTE Ethernet I/O or NTX expansion I/O models.

Modules have conditional logic computing.

Acromag’s new BusWorks® NT series remote I/O modules are now enhanced with conditional logic. The conditional logic increases the functionality with a system of rules that allows extremely complicated decisions based on relatively simple “yes/no” questions. For example, reading an analog or digital input value can trigger an action to happen as a result. This value could be used to control a relay when one or more conditions occur. Another example would be when a discrete input is ON and a temperature threshold is crossed. More complex math computation and logic are also an option.

“With this new conditional logic capability, users can easily implement rule-based control functions without programming,” states Robert Greenfield, Acromag’s Business Development Manager.

Conditional logic is configured on the NT’s built-in web configuration page. No programming is required. The modules support up to 64 conditions using IF/THEN/ELSE statements.

NTE Ethernet I/O models have dual RJ45 ports and a webserver with Modbus TCP/IP and Ethernet/IP communication to monitor or control the internal I/O channels.

Loop powered indicators.

The VPM2000 Series of loop-powered display meters with process current output and alarm capabilities is the latest addition to the Acromag Verty ™range. They supplement the digital indicator functions of a panel meter with optional 4-20mA isolator output and/or alarm trip solid-state relays. A dual-line LCD display has large 0.7 inch digits, an optional bargraph, and a backlight for clear visibility in bright sunlight or dim lighting. The backlight glows red and flashes under alarm condition. No separate power supply is required for easy installation almost anywhere. They are even UL/cUL approved for use in hazardous locations requiring intrinsically safe, non-incendive devices.

“These versatile instruments combine the functionality of a 4-20mA signal isolator, a dual-relay limit alarm, and a digital display in a single unit that is powered off a process current loop” explained Robert Greenfield, Acromag’s Business Development Manager.

The VPM2000 displays are simple to set up and install. USB connection to a PC makes setup fast and easy with the free configuration software which can save the file for copying to other units. Front-panel pushbuttons can also set operating parameters and serve as function keys to change the display or acknowledge alarms. A shallow-depth 1/8 DIN enclosure with a NEMA 4X IP65 front panel facilitates mounting. Internal PCBs are conformal coated for protection from the elements while a -40 to 75°C operating range enables use in extreme environments.

Other advanced capabilities add further value. Two open collector outputs and a digital input are standard. The discrete outputs are useful for alarm indication or pulse output. The discrete input can trigger or reset alarms. Square root, exponential, and linearizer calculations perform scaling for flow and volume computation. The two-line display can show the measured process value in different scales such as tank height on the top line and volume on the bottom. Pushbuttons toggle display of min/max values or other units. Dual relays enable a variety of alarm trip configurations for high/low, high/high, and low/low limit triggers. Relays can also be used for process on/off control and pump alternation applications with display of runtime and cycle counts.

Digital indicating signal conditioners.

The first release from Acromag’s new Vertu™ brand of innovative instrumentation is the VPM3000 Series of universal input displays with transmitter and alarm capabilities. These instruments combine the digital indicator function of a panel meter with optional signal conditioning for 4-20mA transmitter output and/or alarm trip solid-state relays.

“These versatile signal conditioners can satisfy requirements for a process or temperature transmitter, alarm trips,and high-visibility display with a single unit” asserts Robert Greenfield, Acromag’s Business Development Manager.

The big and bright 1.2 inch (31mm) high numerals are clearly visible from far away, even in bright sunlight. Field-selectable inputs accept process current/voltage and temperature sensor signals including 4-20mA, ±20mA, 0-10V, ±10V, Pt RTDs, and most common thermocouple varieties. For additional versatility, units can provide power to drive a 4-20mA transmitter and other instruments. Modbus RTU serial communication is also supported.

The VPM3000 displays are easy to set up and install. Units are configurable using the front-panel pushbuttons, free Windows software, or a copy function from other units. Models are available for operation from 85-265V AC or 12-36V DC power sources. AC units can provide single or dual isolated 24V DC supplies to power a 4-20mA transmitter or other instruments. A shallow-depth 1/8 DIN enclosure with a NEMA 4X front panel simplifies installation. UL/cUL listing meets industrial control equipment safety requirements.

Other advanced capabilities add further value. In addition to converting sensor signals to a scaled 4-20mA current for retransmission to controllers or recorders, units can also perform flow computation functions. The square root function can linearize the signal from a differential pressure transmitter to display flow rate in engineering units. A low-flow cutoff feature sets a user-defined threshold that forces the display to zero for slow flow rates that often produce unsteady output from a differential pressure transmitter. A pushbutton easily toggles display of min/max values. Dual relays enable a variety of alarm trip configurations for high/low, high/high, and low/low limit triggers. They can also be used for process on/off control and pump alternation applications. For desktop monitoring and data acquisition applications, the free software can display and log data from multiple meters on your PC.

The narrow 17.5mm housing mounts easily on a DIN rail. Hazardous location approvals, high noise immunity, and a -40 to 70°C operating range make these transmitters ideal for use in harsh environments.

“These software-configured bridge sensor transmitters offer capabilities not possible with DIP switches or pot adjustments for a broad range of load cell, strain gauge, weight and force measurements,” stresses Robert Greenfield, Acromag’s Business Development Manager.

The TT351 input circuit allows true 6-wire bridge measurement and includes an adjustable bridge excitation supply (4 to 11V DC) with a remote sense feature. Sense wires ensure the programmed excitation voltage is applied at the sensor and enable lead-wire compensation. The differential input performs true ratiometric conversions for extremely stable measurements that remain accurate over time and temperature. Plus, lead break detection is inherent in the device. Three-way isolation between input, output and power increases safety and noise immunity.

Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile strain/load measurement device. A single model can process strain gage, load cell, and millivolt input signals from 1-10mV/V. Initial bridge offsets or forces can be automatically removed with null compensation, tare, and zero balance bridge functions. An internal half-bridge can perform half and quarter bridge completion with precision resistor pairs or bias a floating millivolt input signal. A custom input signal linerarizer function supports up to 25 user defined signal breakpoints. Flexible scaling is independently adjustable on the input and output. To suppress noise effects, users can set a variable digital input filter level or average a number of samples. Shunt calibration tools with a simulation calculator enables rescaling of the transmitter’s indicated strain by modifying software gain and/or the instrument gauge factor. And to test or verify operation, a software diagnostics screen will poll the unit and display measured and computed values.

Programmable Signal Splitters.

Acromag’s new uBSP signal splitter/duplicator acts as a carrier for their microBlox line of plug-in signal conditioning modules to drive two scalable 4-20mA or 0-10V control outputs and an auxiliary 5V third output from a single input.

Users can select from more than ten miniature signal conditioning modules to process inputs from RTDs, thermocouples, two-wire transmitters as well as a variety of current, millivolt, or voltage sources. The interchangeable input modules snap into the uBSP carrier which provides input and output terminal blocks plus a USB port for easy software configuration from a Windows PC or Android mobile device.

“This modular, programmable approach provides an extremely flexible solution to many complex signal splitting applications,” explains Robert Greenfield, Acromag’s Business Development Manager.

The uBSP signal splitter’s USB port allows users to customize the I/O ranges, scaling, and other operations driven by the inserted microBlox signal conditioning module. The powerful configuration software is free and a common mini-B USB port eliminates the need for expensive proprietary cables or adapters to connect with your PC, smartphone, or tablet.

With the plug-in microBlox modules, users can change the input type quickly and inexpensively as requirements change. 1500V isolation safely separates the input from each output circuit to prevent damage to other instruments from surges. Two-wire transmitter input modules provide field excitation for the transmitter. RTD input modules support 2, 3, or 4-wire sensors with excitation, linearization, lead-wire compensation, and break detection functions. Thermocouple input modules support types J, K, R, S, T and E with linear or non-linear output.

To ensure reliable performance, units are highly immune to electrical noise and operate from 40 to 75°C. Power sources from 6-32V DC are supported to simplify battery and solar-powered applications. Units mount securely on a DIN rails with 25g shock and 4g vibration resistance. Hazardous location approvals are pending for UL/cUL Class 1 Div 2 and ATEX/IECex Zone 2 standards.
