The least common multiple of all the loop times on a given link.
Milliamperes Direct Current
A term used to describe signal processing in a device that is not defined by
Modbus specifications.
Millimeters of Mercury
Modbus is an industry standard protocol used in many SCADA packages for
network control. The transmitters can be inserted into existing networks using
Modbus or linked directly to a controller over an RS485 link. Modbus TCP/IP is
available through the Ethernet interface.
Millivolts
Meter Body Temperature
A part of the software and configuration data in a Foundation Modbus device
that handles the management of the network.
Part of the device software that operates on network management objects.
A collection of objects and parameters comprising configuration, performance
and fault-related information for the communication system of a device.
Newton. Meters
National Pipe Thread
Non-Volatile Memory
Definitions and descriptions of network visible objects of a device. There are
various object dictionaries within a device. The dictionaries contain objects and
their associated parameters which support the application in which they are
contained.
Entities within the FBAP, such as blocks, alert objects, trend objects,
parameters, display lists, etc.
Pressure
Measured static pressure in PV4 algorithm
A value or variable which resides in block objects
Absolute critical pressure of the gas
Static pressure at downstream point
Measured differential pressure in Pascals in PV4 algorithm
Absolute pressure of flowing gas
Process Manger
Reduced pressure
Proportional Integral Derivative control. A standard control algorithm. Also,
refers to a PID function block.
