Hard @ Work

pcmaccartney1.....I would like it in a floating register, only for the simple reason that there is no DINT available in PLC-5 and it would be easier to work with than trying to use 2 INT to display the distance.  Even though it would be a floating register, I would not need to use the decimal values as there would be none.  If I could display the value in 1 INT register only, I would do this, but because an INT register is only capable of 32767, and the value/span would be greater than 32767, in this case 152, 400, I need to some how get it into a Floating register to work with.   When the value is smaller that 32767, it is ok, but anything higher than 32767 is the problem.  But the problem I am having is I am guessing I need to first get it to 2 INT from a string, before I can get it into a floating register.  Is there something I am missing??

Hi guys, I think I know the answer to this question, but would like to ask it just in case there is some miraculous logic out there.  What I need to do is read a string from an ASCII device and convert it to a floating register.  This is not the difficult part, my dilemma is, the HEX value that I am reading from the ASCII device is 4 bytes in length, so "#### ####".  The highest possible value would be "FFFF FFFF" hex.  How can i convert this to a floating register while in the process of doing this conversion need to convert it to an integer first where even just FFFF(hex) = 65535(dec).  The application is a measuring device that measures only in (mm) and will be measuring long distances up to 152,400 mm.  There will be no decimals.

Hi Ken, thanks for the reply.  That's what I was thinking as well, but just wanted to check and see if anyone knew otherwise.  I have already visited RTAs website and looked at their device.  Will probably go that route.   Thanks again.

Anyone have any ideas?

First time posting on this forum, hoping some of you could answer a question I have.  I am currently using the MSG instructions with service types "Socket Create", "Open Connection" and "Read Socket" on a Control Logix PLC to communicate to a device over TCP/IP.  My question is, can this also be done with a PLC-5, as when I look at the MSG instruction within PLC-5, there does not seem to be an option for these types of services. Thanks in advance.
