The PC passes the begin-operation signal to the PLC through the serial interface between the MicroLogix PLC and the PC. New inspection programs are also loaded across the serial connection from the PC to the PLC as needed, as well as other non-time-critical operations.

Extension modules
PLC I/O number can be increased through certain additional modules by system extension through extension lines. Each module can contain extension both of input and output lines.
Extension modules can have inputs and outputs of a different nature from those on the PLC controller. When there are many I/O located considerable distances away from the PLC an economic solution is to use I/O modules and use cables to connect these, over the long distances, to the PLC.
If you find a Click'N'Load link, just click on it, and jd will open it. May 09, 2012 Click'n Design 3D is a nice software solution that could come in very handy for those who want to personalize CDs and DVDs by adding custom labels. Click n load easy software free. Click'n'Load 2. This site helps developers to implement CNL on their own site. Most important thing about CNL. CNL is not a linkcontainer. It is not a method to hide links, but a comfort feature to add links to JDownloader very easily. Basics about CNL.
Remote I/O connections
When there are many I/O located considerable distances away from
the PLC an economic solution is to use I/O modules and use cables to
connect these, over the long distances, to the PLC.
Remote PLCs
In some situations a number of PLCs may be linked together with a master PLC unit sending and receiving I/O data from the other units.
Cables
Twisted-pair cabling, often routed through steel conduit. Coaxial cable enables higher data rates to be transmitted and does not require the shielding of steel conduit.
Fiber-optic cabling has the advantage of resistance to noise, small size and flexibility.
Parallel communication
Parallel communication is when all the constituent bits of a word are
simultaneously transmitted along parallel cables. This allows data to be transmitted over short distances at high speeds. Might be used when connecting laboratory instruments to the system.
I forgot to ask before, but you weren't using mismatching 32bit/64bit avs and vdub, right? Otherwise it wouldn't work out. I'm back to square one with opening up AVS files in VirtualDub. Suggestions to bring forth in case you were already on matching 32bit (if you weren't just use the 32bit stable versions first): 1) Try to update avisynth to the latest alpha version, currently 2.6.0 Alpha 4: 2) Try to use the 1.10 experimental branch of virtualdub: Do make sure you use the 32bit version of everything, otherwise it's not gonna work.

Parallel standards
The standard interface most commonly used for parallel communication is IEEE-488, and now termed as General Purpose Instrument Bus (GPIB).
Parallel data communications can take place between listeners , talkers , and controllers. There are 24 lines: 8 data (bidirectional), 5
status & control, 3 handshaking, and 8 ground lines.
Serial communication
Serial Communication Between Pc And Plc Lighting Controller
Serial communication is when data is transmitted one bit at a time. A data word has to be separated into its constituent bits for transmission and then reassembled into the word when received. Serial communication is used for transmitting data over long distances. Might be used for the connection between a computer and a PLC.
Serial standards
RS-232 communications is the most popular method of plc to external device communications. RS 232 is a communication interface included
under SCADA applications. Other standards such as RS422 and RS423
are similar to RS232 although they permit higher transmission rates and longer cable distances.
There are 2 types of RS-232 devices:
0001 DTE – Data Terminal Equipment and a common example is a computer.
0001 DCE – Data Communications Equipment and a common example is a modem.
PLC may be either a DTE or DCE device.
ASCII
ASCII is a human-readable to computer-readable translation code
(each letter/number is translated to 1’s and 0’s). It’s a 7-bit code, so we can translate 128 characters (2^7 is 128).
Difference Between Pc And Plc
Protocols
It is necessary to exercise control of the flow of data between two devices so what constitutes the message, and how the communication is to be initiated and terminated, is defined. This is termed the protocol.
One device needs to indicate to the other to start or stop sending data.
Interconnecting several devices can present problems because of compatibility problems.
In order to facilitate communications between different devices the International Standard Organization (ISO) in 1979 devised a model to be used for standardization for Open System Interconnection (OSI).
