Fully Integrated Modbus Communication Functions on STARDOM PLC/RTU |
|
STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.
|
|
|
Two-way Communication Feature of FOUNDATION fieldbus™ |
|
Gas flow data calculated by an RTU can be sent back to a transmitter using the two-way communications capability of FOUNDATION fieldbus.
|
|
|
SCADA-RTU Communications Using GPRS |
|
To make the most of the advantages of GPRS, Yokogawa's STARDOM FCN/FCJ intelligent RTUs and FAST/TOOLS SCADA package have several functions that reduce the number of packets that must be sent. This dramatically lowers communication fees.
|
|
|
Impulse Line Blocking Diagnosis |
|
Operators must receive diagnostic information before a line block leads to a malfunction. Yokogawa provides predictive diagnostics based on trend analysis of the blocking factor, which improves maintenance efficiency and reduces maintenance costs.
|
|
|
Measurement in Cogeneration and Captive Power Boiler |
|
Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.
|
|
|
Vortex Flowmeter in Water/Steam Injection |
|
The major methods of improved oil recovery are water flooding and steam injection. "These technologies make a tremendous contribution to recovering additional oil from old wells as well as improve primary recovery of operating oil fields."
|
|
|
Meter APPF in Gas Pipeline Metering |
|
Yokogawa provides controller embedded flow calculation library based on AGA (American Gas Association) reports.
|
|
|
Autolevel |
|
Level transmitter configuration can be very time consuming. DPharp transmitters with advanced software functionality eliminate this time consuming task. With maintenance shops getting smaller, finding equipment that allows us to do more with less becomes a priority.
|
|
|
Low Flow Cut-off |
|
One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.
