  1. I'm working on a scanning project that scans barcodes of 2 parts during assembly to compare them. I'm using 1 scanner connected to the serial port. I need the operator to scan the first barcode, then he should be prompted to scan second barcode, then compare the 2 strings. I need help on how to prompt to second scanning after handling and saving the first input. Should I just fill the buffer with 000 then put a rung to receive data through the port again?
  2. Hi, I am trying to read and log the output of the third party device (in this case a LGR trace gas analyser connected to a value manifold also controlled by the PLC) using a US5-B10-T24 PLC. The device returns 31 columns of data as a 521 character hexademical message. Of this I need to record at least columns 1, 2, 4, 6 and 8. The first column is a timestamp formatted as "dd/mm/yy hh:mm:ss.sss" and the subsequent columns are data values in scientific notation in the format "x.xxxxxe+/-xx" e.g. 1.56789e-01. I am able to use message composer and parse message to store this inf
  3. Hi, This is -hopefully- a relatively simple question, but I'm a bit out of my depth so apologies if I manage to confuse the situation with imprecise terminology! I need to read (and ultimately log) the serial output of a third party device to a Unistream PLC. The device outputs six values (e.g. 5.10945e1 1.00361e2 -2.58244e2 -1.2803876e-1 8.77776e1 2.5464391e-1) as string (hexidecimal, length 70) that ends with a return (OD) and new line character (OA) e.g. I can read this string into a buffer tag using the Com Rx function and I can see in online mode that the data arrived
  4. I am working on a project that has a somewhat involved communication routine to read multiple values from an instrument. This requires that I have several long messages in message composer that I am using to both request the data and also to parse the response. I will need to use this technique in several different projects. Is there any way to export the messages from the message composer and then import them into a new project? It takes several hours to manually rebuild these messages in each new project.
  5. Is there any chance of the future holding a feature that would compose reports to printers? something to the likes of the email message composer. put in text, variables, etc and have a ladder FB that when triggered would send out to a printer via USB or TCP? I know there is an example file for a TCP printer, I've looked it over, not live tested yet. It's complex to say the least. I would love to get my Unistream client daily reports printed out direct from PLC. The old Foxboro round paper charts with the red ink go in the garbage on most upgrades, the onscreen displays (trends) and emails are
