How to Monitor Temperature in a Production Furnace – 8401034

Defining the Problem: A manufacturer of specialty furnaces needs to monitor their temperature control, provide warnings/alarms for temperature near fault conditions, and document consistent temperatures throughout the sintering process. System Requirements: The solution must take a signal from a thermocouple, have a display for real time visual feedback, record temperatures throughout the batch production for…

How to Display Flow Rate From a DP Transmitter – DP Flow via Square Root Extraction

Acromag Solutions Application Note 8401035 Defining the Problem: A water treatment facility has differential pressure transmitters that output a 4 to 20mA signal to their SCADA system. They also want to be able to display the flow rate to the operators working nearby but the signal from the differential pressure transmitter is nonlinear. System Requirements:…

How Does Conduction Cooling Keep Heat in Check? – 8400530

Keeping Heat in Check: Conduction Cooling Expands Application Boundaries Current application demands of XMC Mezzanine Card (XMC) modules have grown from the simple addition of I/O and low-level communications to the servicing and off-loading of high performance software defined radio (SDR), digital signal processing (DSP), co-processing, and now re-configurable FPGA-based computing with gigabit interfaces. This…

How to Set Up Communications between HMI and Remote I/O Demo – 8400643

Demo Program: How to Set Up Communications between IDEC HMI and Acromag 965EN Scope To establish communications between an IDEC HG3G HMI, set up as a Modbus/TCP master, and Acromag’s 965EN Remote I/O, set up as a Modbus/TCP slave. IDEC HMI Setup Projects for IDEC’s HG3G series of HMIs are created with WindO/I-NV2 software. To…

How to Connect Ethernet I/O Modules with RadioLinx Ethernet Modems – 8500770

Connecting Acromag Series 900EN I/O Modules to an existing network with RadioLinx Ethernet Modems Background – IP Addresses Any TCP/IP packet contains two addresses: a unique fixed MAC address, and a unique IP address. To communicate on the Internet, computers must have unique identifiers in order to differentiate one computer from another. This is accomplished…

How to Use a Modbus/TCP Module as Remote I/O with a Honeywell Controller – 8400640

How to Use Acromag’s 967EN Modbus/TCP Module as Remote I/O with Honeywell HC-900 Hybrid Controller The Acromag 967EN has eight analog 4-20mA inputs. It is a Modbus/TCP slave; thus ideal for use as remote I/O with a Honeywell HC-900 Hybrid Controller (Process Automation Controller) that runs as a Modbus/TCP master over a standard Ethernet network…

How to Use Acromag 600T Series Isolated Transmitters – 8401028

Application 1 Re-transmitting a signal from a two-wire loop to a second location. Solution Use either a model 651T-0600 (single channel) or 652T-0600 (dual channel) transmitter. Application 2 Splitting a signal from a two-wire loop: two outputs for different locations. Solution Use either a 653T-0600 (single input, dual output) or 652T-0600 (dual input, dual output)…
