2,4-DNP can mean:
DNP3 (Distributed Network Protocol) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. Usage in other industries is not common. It was developed for communications between various types of data acquisition and control equipment. It plays a crucial role in SCADA systems, where it is used by SCADA Master Stations (aka Control Centers), Remote Terminal Units (RTUs), and Intelligent Electronic Devices (IEDs). It is primarily used for communications between a master station and RTUs or IEDs. ICCP, the Inter-Control Center Communications Protocol (a part of IEC 60870-6), is used for inter-master station communications.
While IEC 60870-5 was still under development and had not been standardized, there was a need to create a standard that would allow interoperability between various vendors' SCADA components for the electrical grid. Thus, in 1993, GE-Harris Canada (formerly known as Westronic, Inc.) used the partially completed IEC 60870-5 protocol specifications as the basis for an open and immediately implementable protocol that specifically catered to North American requirements. The protocol is designed to allow reliable communications in the adverse environments that electric utility automation systems are subjected to, being specifically designed to overcome distortion induced by EMI, aging components (their expected lifetimes may stretch into decades), and poor transmission media.
DNP is a three-letter abbreviation which can stand for:
I’m stuck… in a traffic jam,
Hands to my head as the lights turn red
I’m stuck… feels like quicksand
And times running out, gotta figure this out
Yeah it’s on… World War 3
As my head, my heart disagree.
Head says no, heart says yes, I’m my own worst enemy
(Chorus)
I’m forbidden, yes forbidden, I’m forbidden to say that
I love you…
I’m forbidden, yes forbidden, I’m forbidden to say that
I love you…
And I’m damned if I do, shamed if I don’t…
Yeah I’m forbidden, yes forbidden, I’m forbidden to say
that I love you…
One year, it’s like a lifetime with you all alone,
we've been through it all.
I can’t, no I can’t be a murderer
Just given it all, what more could they want than love!
Hey, in a second; we were lost now found once more
What feels right, seems so wrong
Yeah the truth will never lie…
(Chorus)
I’m forbidden, yes forbidden, I’m forbidden to say that
I love you…
I’m forbidden, yes forbidden, I’m forbidden to say that
I love you…
And I am dammed if I do, shamed if I don’t…
Yeah I’m forbidden, yes forbidden, I’m forbidden to say
that I love you…
Dammed if I do, shamed if I don’t
Torned if I do, blamed if I don’t
(Chorus)
I’m forbidden, yes forbidden, I’m forbidden to say that
I love you…
I’m forbidden, yes forbidden, I’m forbidden to say that
I love you…
And I am dammed if I do, shame if I don’t…
Yeah I’m forbidden, yes forbidden, I’m forbidden to say
that I love you…
I’m stuck… in a traffic jam...
