  1. Logic to control many motors

    Hi everyone, I trying to develop a logic to control 6 motors. Two motors needs to working and four motor will be in stand by. When one of the two motors fail, one of the four motors will start to work. Another rule is, when one of the motors that is working reach the preset time of working, the controller will stop that motor and start another motor with low working time, and so on. I'm have difficult to solve this problem. Can someone help me, please? Best, R.  
  2. Remote access to PLC

    For FX3U PLC remote access is possible or Not through teamviewer software? if yes...How i want do this? But i am using communication is GT10-RS2TUSB-5S cable.  thank you.
  3. Hello, I need to Synchronize two 4kW motors connected to their own individual AltiVar VSDs. To put it simply the two motors are pulling cables on a pulley and when loaded the motor's slip and the speed varies. I have an Omron CP1L-EM PLC and 2x Omron Rotary Encoders ( E6C2-CWZ5B encoders - 360 PPR) - connected to each motor,   What is the best way to read the pulses from the two rotary encoders then convert to RPM? 1) Using  PRV or PRV2(883) instruction,  - this would be the best option as it would convert the value to RPM - however, can I use this instruction on both Counter 0 & Counter 1? 2) Or read the raw value from  Counter 0:  A270 (connected to motor one's encoder) Counter 1: A272 (connected to motor two's encoder) Convert the pulses to RPM - then compare and adjust? 3) Or using CTBL. - is this a useful instruction for this application?   Once I get the RPM speed from each motor - I can then do a compare instruction - see if there is a mismatch and if so send a scaled analogue output to the VSDs to correct the speed if required. (10-50Hz) What would be your recommendations? any help would be most helpful. Thank you.
  4. Which one Baldor Motor is best for Industrial purpose like food processing?? Please suggest .
  5. Starting Multiple Motors / Pumps

    Greetings, We (in the steel industry) have many pumps / motors (large and small).  Generally we use soft-starts,  cross-line starters (E3+) or even Flex drives. There may be several motors in a pool to start where we need only say 2 of 3 to be running at any one time  When it's time to start them, we may need to stagger start them, if one fails, the spare may need to start.  My question to the group is... Are there any philosophies out there (and hopefully pseudo or actual code) as to how to start a subset of motors/pumps within a pool of motors and maintain the configuration running ? I appreciate any and all comments. David 
  6. Hi, I am tasked with doing some research for our company. (automation / controls ) and wondered if anyone here might know of a resource to find out what platforms they are using at the various GM plants. I'm looking for the Process PLC / Safety PLC / HMI software. Much thanks,  
  7. Background information: I am doing a writing assignment about ICS and the importance of security in these systems and one of the requirements is to do some primary research on the topic that you choose. I created this survey that will satisfy the requirement. I don't need a lot of responses, around 15 is fine. This survey asks questions about Industrial Control Systems Security and I need some volunteers to take it. All of these responses are meant to be anonymous. Link: Thank you!
