Application Note: Record Building Water Usage with Remote Ethernet I/O
This document illustrates using Acromag's XT1211 discrete I/O modules to communicate via Modbus TCP/IP and aid in monitoring the usage and quality of water used by a school.
Defining the Problem:
Regulatory Compliance - To meet environmental standards by monitoring the usage and quality of water used by a school. System will record the temperature, pressure, and flow rate for reporting purposes.
System Requirements:
Field instruments used are pressure transmitters (PT), temperature sensors (T/C), and flowmeters (FM) with 4-20mA outputs. Remote I/O convert the analog inputs to Modbus TCP/IP on Ethernet which communicates with the Building Automation System (BAS) for data logging, trending, and histograms.
| Implementing the Solution: | Featured Products: |
| 1. Configure the module using Acromag Windows® based software via USB connection. | • 8 Differential Current Inputs, Modbus TCP/IP XT1211-000 |
| 2. Connect the field instruments and verify input status using the software test & polling feature | • Software Interface Package XT-SIP |
| 3. Program the BAS with the remote I/O network parameters and Modbus registers. |
Why Acromag:
Acromag provides a simple and cost-effective solution for interfacing data from a number of sensors to building control systems.
