How to Communicate to Ethernet Modules in an Allen Bradley ControlLogix System – 8400495
Communicating to Acromag BusWorks Series 9xxEN-6xxx and XTxxx2-xxx Ethernet Modules in an Allen Bradley ControlLogix System Objective: This document illustrates a procedure for integrating the Acromag Series XTxxx2, and 9xxEN-6xxx modules into the Allen Bradley control system as a third-party generic module. The reference model for this procedure is the Model 961EN-6006. It is assumed…
How to Measure Multiple Load Cell / Strain Gauge Inputs – 8400915
Defining the Problem Very often, load cells and strain gauges are remotely mounted away from a data collection device or a controller. In these applications, converting these input devices to run on an Ethernet network is a better practice than hard-wiring over long distances. For remote measurement, Acromag’s 962EN model for Modbus TCP/IP or Ethernet/IP…
How to Distribute Critical Signals to Multiple Locations at the Same Time – 8401069
A satellite launch company needs to send a discrete abort signal to multiple locations at the same time if anything gets out of specification. The equipment to monitor and control the launch are in several different buildings but all on the same network. Timing is critical and all signals must be sent at the same…
How to Measure Temperature: a High-Density Ethernet I/O Solution – 8401062
Acromag Solutions Application Note 8401062 The Problem: Monitoring up to 500 Temperature Measurement Points A chemical manufacturer has up to 500 temperature measurement points. In addition, they’re monitoring points for pressure, level and flow, and have thermocouple and RTD scattered throughout their process. It would be cost prohibitive to run and maintain twisted pair wire for……
How to Display and Maintain Tank Levels in a Hazardous Area – 8401047
Defining the Problem: A chemical manufacturer has various tanks of substances which it combines to manufacture their product. The tops of these tanks are a UL rated Class 1 Division 2 hazardous area. They use four-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 – 8401036
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 – 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:…
