 The below steps gives us the basic backup procedure required to take backup from the RS Logix 5000 PLC software. RSLogix 5000 PLC projects are stored in a file format with the extension: *.ACD The ACD file encompasses the entire RSLogix 5000 project and is the only file you will need to retrieve. However, it is important to insure you retrieve the program that is currently running in the PLC. The procedure for retrieving a PLC program differs depending on weather you have an existing copy of the PLC program on your computer or now. If Your Computer Has the *.ACD Project For the Controller: STEP 1 – OPEN THE RSLOGIX 5000 PROJECT FOR THE CONTROLLER STEP 2- OPEN “WHO ACTIVE” TO DEFINE A PATH TO THE CONTROLLER STEP 3 – SELECT THE CONTROLLER STEP 4 – GO ONLINE WITH THE SELECTED CONTROLLER STEP 5 – IF THE SELECTED CONTROLLER HAS A NEWER VERSION OF THE RSLOGIX 5000 PROJECT YOU WILL BE PROMPTED, BE SURE TO SELECT THE UPLOAD OPTION STEP 6 – SAVE THE CURRENT RUNNING PLC PROGRAM TO A NEW LOC...

 The  most  popular  form of signal transmission  used in modern  industrial  instrumentation  systems is the 4 to 20 milliamp DC standard. This is an analog signal standard, meaning that the electric current is used  to proportionately represent measurements or command  signals. Typically,  a 4 milliamp  current value represents 0% of scale, a 20 milliamp  current value represents 100% of scale,  and  any  current value  in between  4 and  20 milliamps represents a commensurate percentage in between  0% and  100%. The  following table shows the corresponding  current and percentage values  for each  25% increment between  0% and  100%.   Every  instrument technician tasked with maintaining 4-20 mA instruments commits these values  to memory,  because  they are referenced  so often: For example, if we were to calibrate ...

 Ferrules are identification labels provided for every wire terminations in an instrument, equipment, or electrical/instrumentation control panels. These tube-shaped sleeves can be inserted easily on each individual wire in a multi-core cable. In earlier days fixed digits/letters are used as ferrules, but now Instrumentation engineers/technicians prints out desired ferrules by using a ferrule printing machine. Typical Ferrule The numbers/ letters on the ferrules will be given as per the approved electrical hook up or loop diagrams. This helps technicians to easily identify a particular loop/wiring from a series of terminal blocks and to troubleshoot the desired terminal connection. Separate numbers on the ferrules distinguish the positive and negative polarities of wires, thus ensure the polarity protection of the instrument. Cross Ferruling  As a wire is connected on its both ends, it is quite useful to use a cross reference method for wire identification. Unlike normal ferru...

 Build the ladder logic program to turn ON or OFF the lamp using single push buttons using one shot rising (ONR) instruction. ONE Shot Rising (OSR) Instruction One shot Rising is used to develop a signal/Pulse that is exactly one scan in duration. When a signal is applied to a contact/Push Button, no matter how long the signal stays on, a single pulse of one scan length is generated after the one shot. List of Inputs and Outputs PLC Logic Conditions One Shot Rising PLC Program Program Description RUNG 0000 Start/Stop Push Button is connected with one shot rising bit with the output memory bit. RUNG 0001 Previous rung output bit and Lamp output bit are connected in X-OR gate logic to make the condition possible. Interlocking of output bit is used to turn the output ON/OFF in different condition. Conclusion: The above explained ladder logic for lamp turn ON/OFF using single push button is for example only. We can use this example program to understand the working of Push Buttons, one...

 This article discusses about ON delay timer instruction and its working principle using Allen Bradley Programmable Logic Controller (PLC) Ladder Logic. ON Delay Timer In the above On-delay timer instruction, there are totally four parameter, TIMER: T4:0 – Timer File name (Timer T4:0, T4:1, T4:2…) TIMER BASE – How the time need to count, in Seconds, Milli Seconds… PRESET – Limit value of Timer-Up to how much it should count ACCUMULATOR – Running Value of timer when it is in ON condition. Program Description ON delay timer purpose is to delaying the ON time, Example : After the turning ON of main switch, Air Conditioner takes nearly 5s to 15s to turn ON. On Delay Timer using PLC RUNG 0000 Start and Stop Switch is to turn ON/OFF the timer. RUNG 0001 When start switch is pressed, Timer Enable bit (T4:0/EN) is turned ON to show the status of TIMER ON/OFF condition RUNG 0002 When start switch is pressed, along with the timer enable bit timer timing bit also turned ON to show the status ...

 This article discusses about OFF delay timer instruction and its working principle using Allen Bradley Programmable Logic Controller (PLC) Ladder Logic. Timer OFF delay is to delaying the turning OFF of any output, Example-Setting timer to turn off Induction Stove, TV remote settings to turn OFF TV after certain time. OFF Delay Timer In the above OFF delay timer instruction, there are totally four parameter, TIMER: T4:0 – Timer File name (Timer T4:0, T4:1, T4:2…) TIMER BASE – How the time need to count, in Seconds, Milli Seconds. PRESET – Limit value of Timer-Up to how much it should count ACCUMULATOR – Running Value of timer when it is in ON condition. Program Description Off- delay timer instructions is used to program a time delay to begin after rung input goes false. As an example, when an external cooling fan on a motor is provided, the fan has to run all the time the motor is running and also for certain time (say 10 min) after the motor is turned off. This is a ten minute o...
