  1. I need to program a Red Lion G307K2 so that i can use a bar-code scanner that uses a RS-232 cable. Does anyone know of some good program references or have any sample program that i could use. Also I would like to know of any problems anyone has had with this kind of setup and how to avoid them. Thanks
  2. Thank you dmargineau for the link to the manual and information about the different types of manuals. And thank you chantecler for the sample program code. Between the two sources of information I have been able to write the program that is needed for the machine.
  3. Thank you. None of the manuals i had downloaded had this information in it.
  4. I was able to find the EII and the help file for it. I have to say the help file was almost useless. It said what each part was but not how to use them. Do you know of anywhere i can find program examples and more information on how to properly use the EII function file? I haven't used this part of the PLC before.
  5. I looked at the instruction help and found an IID and an IIE for input interrupts but is said that the instructions only worked in the SLC 5 controllers. Would it work to trigger a move off the input and then compare it to the previous move and calculate the time-passed between the two? Or would the time it takes to execute the instructions skew the results?
  6. The range will be anywhere between 50 to 100 rpm. We will be running several different speeds on the machine and the size of the cylinder will change slightly between products.
  7. I need some help with some programing to calculate the RPM of an object to use in a PID control. I am using a MicroLogix 1100 PLC in this project. The setup for the rpm detection is a single reflector and detector wired into one of the high speed inputs of the controller. I need to calculate the RPM that the cylinder is turning at and the use that data to go into a PID to control the speed of the a motor. The motor is controlled by a 0-10 VDC analog output to a speed controller. I am unsure as to how to quickly calculate the current rpm so that is gives me useful data for the PID. Any suggestions or ideas would be greatly appreciated.
