Hi , guys I am trying to intergrate a Datalogic DS2400A Scanner with a Micrologix 1200 ser.C The scanner use a conection Box called C-Box where you can conect the scanner and de RS232 Port The project consist in read barcode at boxes (that go throw a conveyor) , and depending the barcode move the boxes to different conveyor. My question is how to send ascci data (from the C-Box), to the port(comm) of PLC , and if is posible ? I have a idea reading some post of the forum, but i am not sure how to do it. thanks in advance to all PLC people

hi everyone ¡¡¡¡¡ I`m new programing plc`s , and i`ve been reading some manuals of Simatic S7 , i found an example (at the image attach part of the example) about how to use timers, but i want to practice this example with a micrologix 1200 plc, the problem and the question is how can i charge the value of the timer (PT) in a similar way that the Simatic S7 ?? with a move instruction or another .

hi ¡¡¡ i have an application that consist of ASCII Write and ASCII Read instructions, I HAVE A MICROLOGIX 1000 AND I`M NOT SURE IF THIS IS POSIBLE WITH THIS PROCESSOR, SO, IF THIS IS POSIBLE HOW CAN I DO THIS ?? IS IT DIFICULT ?? THANKS IN ADVANCE FOR ANY HELP ¡¡¡¡¡¡

THANKS KEN, IM GOING TO DO SOME TESTS IN THIS APLICATION, BUT MAYBE THE BETER OPTION IS THE 2 LINES THANKS

HI EVERYONE ¡¡ I NEED YOUR HELP, I`M NEW PROGRAMMING, BUT I KNOW , AND I UNDERSTAND A LADDER PROGRAM , BUT I HAVE A PROBLEM, I DON`T KNOW WHAT IS THE BETTER OPTION TO THE FOLLOWING APLICATION: I HAVE A CONVEYOR, AND PACKAGES OF 12 BOOTLES GO THROUGH THE CONVEYOR TO BE LABELLED, I HAVE AN APLICATION LABEL MACHINE (THIS MACHINE THE ONLY THING THAT NEEDS FOR THE APLICATION OF THE LABEL IS A SIGNAL FROM A SENSOR ), BUT DUE TO THE CONDITIONS OF THE SYSTEM AND THE SPEED OF THE CONVEYOR, I NEED TO INSTALL 2 APLICATION LABELS MACHINES WORKING ""INTERMITENT IN THE CONVEYOR"", WITH ONLY ONE SENSOR TO START THE APLICATION OF BOTH MACHINES. ---------------------------------- ---L---------I----I-------------------CONVEYOR SENS 1 2 1.- FIRST APLICATION LABEL MACHINE 2.- SECOND APLICATION LABEL MACHINE L.- SENSOR ----- ----- CONVEYOR WITH THE PACKAGES OF BOOTLES THE QUESTION IS VERY SIMPLE, WHAT`S THE BETTER PROGRAM FOR THIS SIMPLE SECUENCE IF I NEED THAT BOTH APLICATION LABEL MACHINES WORK INTERMITENT IN THE CONVEYOR . I`M THINKING USE A PICO CONTROLLER FROM ALLEN BRADLEY , SO I CAN INTRODUCE A LADDER DIAGRAM. OR I HAVE A MICROLOGIX TOO THANKS IN ADVANCE FOR ANY REPLIES ¡¡¡¡

SORRY KEN, YOU`RE RIGHT , I WAS THINKING THAT IT COULD BE EASY BUT I SEE THAT I DIDN`T HAVE A CLEAR IDEA ABOUT THIS .. ABOUT YOUR QUESTIONS Do you have this much time between bottles? NO I DON`T ,THE BOTTLES GO FAST BY THE CONVEYOR APROX 15 INCHES BETWEEN BOTTLES , APROX 5 SECONDS ONE OF THE OTHER ONE. ********* So...I think you will need a sensor for each machine, and a small plc to make the labellers skip every other bottle. YES I AGREE, BUT HOW CAN I DO THIS ?? IS IT DIFFICULT THE PROGRAM ?? I DON`T KNOW , BUT I WAS THINKING IN SOMETHING LIKE COUPLE AND ODD, DEPENDING THE VALUE THE LABEL MACHINE IS GOING TO APPLY THE LABEL. FOR EXAMPLE IF THE VALUE IS 1 OR 3 OR 5 OR 7 ETC , THE MACHINE #1 IS ACTIVE, IF THE VALUE IS 2, 4, 6, 8, ETC , MACHINE #2 IS ACTIVE, BUT I DON`T KNOW IF I NEED TO USE 1, 2, OR 3 SENSORS, OR IS THERE ANOTHER OPTION ?? THANKS FOR YOUR HELP AND TIME ¡¡¡¡¡¡¡¡

THANKS FOR YOUR HELP KEN: YES, I have a conveyor feeding two lablers. YES, The first bottle comes down the conveyor, makes a sensor, then is lablelled by machine #1. 2nd bottle comes down the conveyor, makes THE SAME sensor, then is lablelled by machine #2. You basically want to flip flop the " active" machine each cycle is that correct? YES , I SUPPOSE THAT I WANT Exactly how does the sensor work? Is there some type of timing between the sensor and the label machine, or does the machine have it's own sensor to detect a bottle is present? YES, EACH MACHINE HAS HIS OWN SENSOR TO DETECT A BOTTLE WITHOUT A TIMING , BUT THIS IS THE CASE WHEN THE MACHINE IS WORKING ALONE , IN THIS CASE (2 MACHINES)I WANT TO USE ONLY ONE SENSOR TO ACTIVATE THE SYSTEM. THANKS ¡¡
