For example, DS/DP310 can send Request query from a supervisory computer
or PLC to a specific Server or to all of the connected devices (in case of broadcast message), collect information from devices measuring temperature/humidity/pressure, and further communicate the results back to PLC.
driverless, FrontRunner-equipped 930E-ATs are each equipped with vehicle controllers, GPS, an obstacle detection system, and a wireless network system operated and controlled by a supervisory computer
." (2) Each truck weighs 200 tons and is capable of carrying an additional 320-ton payload.
Features include cold start inhibit, high and high-high alarms for each pressure point, recipe creation and storage, and a provision for system networking to a supervisory computer
via Ethernet LAN.
The vehicles receive directions from a supervisory computer
that controls and monitors movement of AGVs and communicates with existing programmable logic controllers (PLC) and warehouse management systems to facilitate movement of finished product.
It can be used as a high-integrity, stand-alone flow computer or as a building block for integration into a supervisory computer
The required networks must be based on industrial standards for hardware and protocols, in order to ensure communication between the individual control sub-systems and the supervisory computer
of the baggage conveying system.
Functions of this supervisory computer
may include combinations or individual plant factors such as:
An alarm lets the operator know when the process is over and it's time to unload." Star-Kist's system consists of local controllers with operator interface panels at each retort, networked to a central supervisory computer
, which is a DOS-based desktop PC.
Moore, supervisory computer
specialist, says before ISDN the only way her staff could use the printer they wanted was via "Sneakernet,"--walking a disk over to fellow worker Penman's office and tying up his PC while the printer completed their jobs.
The company's CIM-1 program, for example, incorporates all processing and auxiliary equipment, and all post-molding processes, into a master network connected to a plant's supervisory computer
. The computer automatically searches process variables and provides a warning when a deviation occurs.
