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 .

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

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 ¡¡¡¡¡¡

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 ¡¡

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 ¡¡¡¡
