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 bit tag is updating at the correct rate and that the hexidecimal values received by the buffer tag seem to respond sensibly. However, I'm stuck trying to understand how to go about defining the contents of the buffer tag as a message in Message Composer so that it is recognised by the Parse Message function. I would greatly appreciate any suggestions about how to do this or resources that might help me better understand my problem! I have found useful information here and in the video tutorials but I'm obviously still lacking some critical piece of knowledge! Ultimately I would like to end up with 6 data tags containing ASCII values that I can append to a .csv file created elsewhere in the program, but I'm not at this moment clear on the steps in between. Hopefully the above makes sense, if not I'll try again! Many thanks in advance, Sam
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.
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 great, however some still like/require that data on paper. Paper: that nostalgic, almost extinct white stuff.
