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 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 Communicate with Acromag Ethernet/IP Modules from CompactLogix Controllers – 8500762

Communicating with Acromag Series 9xxEN-60xx and XTxxx2-xxx Ethernet/IP™ Modules from CompactLogix™ Controllers This document illustrates a procedure for configuring message commands intended for Acromag Busworks® Series Ethernet/IP modules using Ladder Logic programming software in addition to a CompactLogix Programmable Controller. It is assumed that the user has a working knowledge of; Ladder Logic programming and…

How to Control a Remote Pump for a Natural Gas Pipeline – 8401048

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 – 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…
