How to Communicate with Acromag Series 9xxEN-60xx & XTxxx2-xxx Ethernet/IP Modules from Compact Logix Devices Application Note
Communicating with Acromag Series 9xxEN-60xx and XTxxx2-xxx Ethernet/IP Modules from Compact Logix Controllers This document illustrates a procedure for configuring message commands intended for Acromag Busworks® Series Ethernet/IP modules using ladder logic programming software and a Compact Logix Programmable Controller. It is assumed that the user has a working knowledge of ladder logic programming, the…
How to Control a Remote Pump for a Natural Gas Pipeline
Defining the Problem: A natural gas pipeline has a remote pumping station a mile away and they need to be able to adjust the pumping rate without driving to the site. The pump is controlled by a variable frequency drive. Running control wire is too expensive and also undesirable due to potential surges from lightning…
How to Display and Maintain Tank Levels in a Hazardous Area
Defining the Problem: Chemical manufacturer has various tanks of substances which it combines to manufacture their product. The top of these tanks are a UL rated Class 1 Division 2 hazardous area. They use 4 wire non-contact level sensors and want their operators to be able to read and adjust the tank levels either automatically…
How to Implement Smart Load Sharing with a Pump Controller Application Note
Defining the Problem: A local Public Utility District has a freshwater collection tank that sometimes fills rapidly and other times slowly. At times the main pump could not keep up and a backup pump must be turned on to keep up with the incoming water. The problem is that with the primary pump running most…
How to Monitor Temperature in a Production Furnace Application Note
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 Application Note
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: The panel meter must be…

How to Keep Heat in Check with Conduction Cooling Application Note
Current application demands of PCI Mezzanine Card (PMC) 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 trend of putting more and more processing power on…
How to Use Process Transmitters to Provide a High Voltage Output Up To ±20V DC Application Note
Defining the Problem: We are developing a 12V DC battery simulator that reaches 14.4V when charging. Our controller output cards are limited to 10V and we need a device that can step up the output to 15V. Typical process signal conditioners have standard ranges of 10V maximum. We require a device with a higher output…
How to Remotely Control AC Power for a WEB Server Using an Acromag ES2113 or a 989EN-4C16 Ethernet Digital I/O Module Application Note
Objective This document outlines the steps taken to use an ES2113 or 989EN DIO to control a latching relay that is used to open or close the AC power (115 VAC) path used by a multi domain WEB server. In this mode of control the DIO is configured to a static IP address and is…
