  1. Just got back from a conference. Thank you all so much for the responses. I will go through them and let you know what happens. Thanks.
  2. Laser sensors. To be more specific, a large overhead crane. The lasers are mounted on the bridge and trolley and aimed at stationary structures ( a wall). So essentially what I have is a cartesian coordinate system with continuous data that gives me position (x, y). I currently report the position with a live reading of the lasers on my "run" screen. What I want to do is have the operator move the crane to the origin, record that value (it may be offset from (0, 0)) then move it to the opposite point and record that position. Have that data scaled to the size of the screen, then in real time graphically report that position on an HMI screen. For sake of simplicity mathematically assume my coordinate system is (0,0) meters to (800, 480) meters. Lets say that I represent my life position with a red circle. At (400, 240) my red circle would be at the mid point of my HMI screen. I want that to move as I move position in real time. Without any further research the only way I can think of to do this would be to overlay a red circle and every possible point with a visibility rule of when (x,y) = live (x,y). It seems like a brute force method. I was hoping for a much more elegant solution.
  3. I Have a system that I am using two sensors to located my x and y position within a predefined area. Lets say for the sake of argument that my x and y both range from 0 to 100 meters. Is there a way I can show my position in real time on my HMI screen?
  4. The device I would like the Unitronics US5/7 to communicate with would be the agent. So I cannot get traps from another agent why would the general struct have both sent AND received tags?
  5. I am using a US5/7-x5-T42 combo unit in a small enclosure that customers often install in areas that are not easily accessible. So via Ethernet connection I have a FL WLAN 1101 ethernet radio set up as an AP for VNC access. Sometimes these are standalone units and sometimes they are networked with PLC communication via wireless AP-Client mutually transparent bridge and EtherNet/IP. I dont always have the opportunity to do a site scan to make sure the radios leave configured the least amount of interference so I am trying to build in the ability to scan, display, and make changes to the radio configuration. The radio has an impressive GUI via web browser, but I don't see any way to make use of that with the model PLC i am using and I cannot switch models. So unless I missed something with being able to use a browser interface on the US5/7 T42, i have to use SNMP. The functionality in the radio via SNMP is within their MIB's but the problem I am having is calling the traps from the PLC. There really isnt a lot of documentation and instruction on using SNMP in Unilogic. At least I cant understand it from the little in the help section. Does anyone know if 1. I can use a browser on the model PLC I am using...in that case that makes things very simple for me. And if not, does anyone know how i can call and set values to traps via the PLC?
  6. I need help setting up third part lasers via RS232. I have the hardware ( UAC-CX-01RS2). I have only modified PLC programs before, and mainly in VISI, u90, Studio5000, TIA portal. I have no idea how to set up seral communication in Unilogic. I have a US5-B5-T42. None of the example code that they have on the website initializes Serial communication. Any help that I can get would be greatly appreciated. Please dumb it down for me!
  7. That did it. Thank you all for your help. I am a ChemE by education so I have some fundamental gaps I need to fill.
  8. I have my power to the controller and the only thing I have actually wired to the controller are the outputs to terminals O-0, O-1, O-2, & O-3. The inputs, until I figure, I have left disconnected. For the 24VDC signal I am just taking a 20 gauge wire and jumping V+ on the controller to the input I assigned. For example, with the ladder I posted above downloaded to my controller, I will run the wire from the number 1 position of the input terminal block, to the 15 position on the terminal block. If I simply change the coil to a set coil, it works to set the relay. But, as I stated above, as when I remove the 24V signal I need the relay to go off. With a set coil it stays energized. If I had my wiring wrong, I would expect it to not work with the set coil.
  9. If I change the code to this...it works...but it latches. I need momentary, only while the signal is high.
  10. I downloaded this to the controller....ONLY that just to see if I could get the I/O to work...I get no response when I apply 24VDC to I0 (#15). Just in case I was mistaking about the physical address I applied the signal to all the Inputs...no response. If I jumer 24VDC O0 my relay energizes. Im overlooking something simple...please help.
  11. I am not an expert in ladder logic. I am modifying some code and I need to code an override of a relay that is on O0 of the Jazz outputs. Im landing a 24VDC signal to I0. When the signal is high, I want the Relay to energize. As soon as the signal is low, i want it to de-energize. I have done this in V350 and Samba, but i cant get it to work on the Jazz. The closest I can get is with the reset and set coils. But that latches it. And it is two high signals that will turn it on then off. For some reason, when I replace the same logic with direct coils, i get no response. Please help!
