  1. Omron CQM1H PLC Online

    Hello everyone, I need help for the titled matter. The problem is that i am using CX programmer v 6.1 trial version 30 days. The error i am getting is PLC failed to connect. so the cable in attachment is right one? It is CN226 USB to Peripheral port cable. DIP switches are all off. Should in set them in on off state? if yes so whats the sequence? Replies will be highly appreciated Thanks
  2. Ok guys, this is more a networking question involving a Stratix 5700 managed switch and 5 machines. The five machines all have set IP addresses from the OEM that cannot be changed. The manufacturer has them set in the program to maintain that IP ,so if it sees the IP change it will change it back. With that being said all Five machines have the exact same IP configuration and I cannot change it without contacting the manufacturer and getting them to change it or sell me the program so i can change it. both options will costs entirely too much in my opinion. With that being said my only goal is to read tags from the PLC on each machine. Is there anyway to set each port on that Stratix switch where i can communicate with each  machine individually without causing them to have IP address conflicts with the other machines that have the same IP address. I hope I explained my question well enough. Thank you in advance for any help on this issue.
  3. I've been building a contraption with linear rails and stepper motors. It has an X, Y, and Z axis. I'm using Velocio PLCs to control the motors which seems to be work well so far. I understand these are not very common and my question are related to general motion control, not Velocio programming specifically. Since I'm new to PLCs, programming, and stepper motion I thought I'd ask for some input instead of trying to reinvent the wheel. I'm to the point in the build where I'll be adding emergency stop/limit switches and am wondering how to go about writing the program; if there's an "industry standard" way to go about it. I figure the PLC will check to see if any switch is active. If one is, drive the motor away from it till it's inactive and store the location. If one is not, drive the motor until a switch activates then back off a until it's inactive and store the location. Drive the motor to the other limit of the axis (the number of steps should be known) to activate the switch, back off and store location. Rinse and repeat for the other axes. Is my approach about right?
  4. Program 16 position rotary selector switch

    I have a 16 position rotary selector switch I'm trying to program to a CQM1 PLC, that I will also be programming to a micrologix 1200 in the future, using CX Programmer. The switch connects to the PLC using 4 inputs, and activates the inputs in a binary pattern 0-16 as I turn the switch. For example: if the switch is wired to the first four inputs of the PLC, and is turned to "9" 0.0 and 0.3 will be activated and 0.1 and 0.2 will not, just like binary 9 = 1001. I have tried several things trying to get the PLC to accept these inputs as a single "data-point," and then convert to BCD or Hex to use in a timer. I'm having no luck! Does anyone have any ideas how this is done? The switch is a Tosoku DPP01 015L20RCB, and because of the age of the PLC my instruction set is limited. Thank you in advance!
