Challenge: Data Collection was Isolated and Had to be Reviewed Frequently
Maintenance personnel at a commercial printing company take continuous level readings throughout their on-site water treatment process to comply with state mandates. A dedicated maintenance person was needed to manually sample and document each individual level at regularly scheduled intervals. Although this data was collected, it was isolated from the plant-wide control system and had to be reviewed at the end of each shift.
Solution: A Banner Engineering SureCross Wireless Network Now Allows Data Reviews in Real Time
A SureCross™ Wireless Network was installed to collect 4–20 mA level readings throughout the water treatment process. A Node with analog inputs was installed at each water level measurement point and a single GatewayPro was mounted inside the maintenance shop.
The maintenance shop is in a separate building approximately 100 yards away from the water treatment area. The GatewayPro offers an EtherNet/IP interface that connects to the existing plant-wide control system. The level data is automatically sampled and can now be reviewed in real time.
Results: Automatic Data Collection and Increased Visibility Throughout the Water Treatment Process
Without increasing maintenance personnel, the company was able to focus on other outstanding issues and still reliably collect the water level data needed to comply with standard water treatment practices. In addition to automatic data collection, they now had increased visibility and logging capabilities throughout their water treatment process. Based on the successful wireless installation, plant managers are now considering other data collection applications throughout the facility, such as collecting storage tank level data and energy use statistics.
Create point-to-multi point networks that distribute I/O over large areas. Input and output types include discrete (dry contact, PNP/NPN), analog (0 to 10 V dc, 0 to 20 mA), temperature (thermocouple and RTD), and pulse counter.
