  1. Produced & Consumed tags

    Thank you so much your answer. In this case do I have to download the plc program again ? Or I only have to create the tags in both PLC and done ?  Thanks ahead.
  2. Hi guys,  I have been thinking about wether can increase the numbers of produced and consumed tags, between my plc-s. Currently I have two plc it already have produced and consumed tags, but unfortunatelly soon we are running out of free tags. I read the manual and it said I can make 125 dint tags, currently we have only an array with 10 element.  If I make a new one and I kinda copy it, with different names, will it be work ?  Or do I have to set something else ?  Can I ruin the communication with the two plcs ?  THanks ahead.
  3. Hi guys. I have a question, with HMI pages. I have to make 20 pages 3 times. Its kind of like layer in layer. At the and of the layers always there are only 2 choices. But ofc course its important the route like what the choose, and what is the order. Like we have to detect lets say first layer page2 second layer page13 third layer is page5 and then we choose the first choice. But if the order is different we have to get a different input from the choice1, like we need different address. I could do that if I make ton of pages, but its sounds crazy. A lot of permutation. (20*20*20*2) I attached a picture maybe its easier to understand if Im not explained well. I am using AB control logix PLC, with logix 5000 software. Do have someone a good and quicker idea, to solve this problem.  Thanks ahead. Any idea is highly appriciated.    
  4. FR-A740

    Hi One of my friend want use more analog output on his vfd. Its a Mitsubishi FR-A740 type. Currently the AM signal is for current, but he needs the speed and frequency too.  As we saw its only one analog output is avaiable, but you guys might know better. Can someone confims our theory.   Thank you.
  5. Hello guys! I'm interesting about rfid communication. I currently using control logix and compact logix plcs, and rslogix 5000 software. I'm wondering if someone can help me with a sample project, or any documentation. Its also can be wonderful if someone can share a project with panelview if its possible. I wanna know about reading and also writing. What type of device do you guys using ? I would like to make a simple program what is contain reading and writing. Thank you ahead any help of yours.     
  6. Hi! I would like to ask your help. I want to know more about the communcation systems what allen bradley use. Most important for me, is Ethernet IP communication, Controlnet communication, Sercos (servo) communication, maybe devicenet communication.  I know I can find some manulas on the web, but I thought I ask it here too, maybe you guys have some more documents which is contain more information. Every information is highly appreciated. Thank you very much guys.  
  7. Hi guys I have an control logix plc im looking for a module which is the same as 1769-ascii module. I know that module is for compact logix. Unfortunately i didnt find a good one for that purpose.  Anybody can help with that ? Thanks ahead.         
  8. Hi guys! I need some help with a powerflex 525 multi speed configuring. I know I have to set the P046 parameter for 2 “DigIn TrmBlk” (source) and  P047 parameter for 7 which means present frequency. This is the speed reference. I need 3 speed, so I will use Terminal 5 and Terminal 6. When both terminal is zero then 10 Hz, when terminal 5 is 1 but terminal 6 is 0 then 20 Hz and lastly if both terminal is 1 then it will be 30 Hz. I will adjust the speed with the parameters: A410, A411 and A412. Terminal 2 would be the forward and terminal 3 would be the reverse direction. I think these two can be two PLC digital output trough one-one relay. It will be counted the distance by an encoder. When it reach the target the run command will be released and the motor will be stopped with the decel time1. Also I will connect the S1 and S2 for safety.   My question is do I have to connect other wires ? Also do I have to remove the jumper between terminal 11 and 1 ? Am I forget something ? Any comment would be highly appreciated. Thanks ahead.  
  9. Hi guys,  Can someone explain me what is the difference between SS1 and SS2 instruction ? I read the help but its not so helpful for me.  THank you so much.
  10. Hi,  Can someon help me with the following question. Like what makes a Kinetix 6000 drive a Guarded drive ? What type of safety stuff can you set to make it more safe.  Is it some parameter ? I am bit confused, by the manual. Should I active it in the PLC program or how ? Or it is some setting like a safe speed or torque.  I would really appreciate any help. Thank you so much ahead.  Have a great day, thanks for the reading.
  11. Hello guys!  Im using RS Logix 5000.  Can someone explain me what is the difference between when a servo is shutdown or disabled ?  I read the help but it says the same. I can assume it like when its shutdown, there is inside some circuit which is not allow the 3 phase for the drive.  Disabled is that when it have the 3 phase but nothing can happen ? Is there any difference with the break ? Like when its shutdown it can rotate until its slow down by itself or the break will be active ?  I tried to uplod a pic but it was not succesful. When you open a servo axis properties and you choose the Fault actions tab. You can find there these settings.    Thanks a lot. 
  12. Motion axis home

    Thank you so much your answer. So basically if there is no motion at the moment and if I choose active homing and the sequence is                     2a: immediate, then as soon as I hit the MAH command the actual position will change immediatelly for the home position. I made for this an example: I tried to drag here a pic but it doesnt worked. The pic shows in the trend like I hit the MAH command and the actual position change form 0 to 400. 400 is set in the Axis prperties homing tab. Also Im using an emulator right now, maybe that why I can see it like its a suddend movement. If it wont be an emulator it will be the same ? Or the motor would be rotate until its reach the position ?                      2b: By a swich in this case how do the servo knows which direction has to go ?                    2c: I see but same question as for 2b.                   2d: I see but same question as for 2b.                   2e: I see but same question as for 2b.   Passive: I dont really understand. I mean okay the axis its not moving but how or when will be the axis reach the home position.    Thanks again. Anyway Im using Studio 5000. I forgot to write it down before.  
  13. Motion axis home

    I have decided to write what is my understanding. At least you guys can see I have tried to understand it :). Active homing: THe Axis is on and when the instruction is set the actual position is immediatelly cahnge for the homing postition without moving the real motor.  If its true Why do we need the MRP instruction thats also overwrite the actual position without moving isnt it ?  Passive homing: If the axis is off and after it will be on again, we have to wait until the first impulse is coming from the encoder. If its set the actual position will be the homing position. Absolute homing : I have no idea, im confused.  Thanks again. 
  14. Hi guys! I need some help to understand what is the difference between an Active, Passive and an Absolute homing. Even if I read the manual still not clear for me. Can you please someone explain me this. If someone could post some pic for represetning it would be fabulous. THanks ahead.
  15. Hi. I would like to ask that like you guys are when using a kinetix servo motor what type of safety conditions are possible ? I found a fault actions label. Is there anything else like between the parameters or so ? Thanks ahead.
