Once the two integers arrive to the destination, it is the device on the other end that will be responsible for displaying these two 16-bit integers as a single 32-bit floating point number. The float value will be sent out as two 16-bit integers. When sending data out of the ProSoft module or gateway, the Float value will have been stored in the memory as two 16 bit integers, rather than a single float. I copy the type bytes into local memory and send them back unchanged on write. You can swap the two words, the bytes within the words, or both.Ĭheck the user manual of your specific module for more information on swap codes. Before the first write, I make sure I do a read. RSLogix Emulator 5000 is a software simulator for the Allen Bradley line of Logix. You may need to try a different ‘Swap Code’ parameter for each MCM Command that is reading a float via Modbus. A Logix5000 controller lets you divide your application into multiple. There may be an issue with the order in which the bytes and/or words were placed when converting to a float. Not all pairs of integer values will comprise a valid float, so it is possible that the resulting float value is not valid. A Length of '1' means the logic will use 2 consecutive integers starting at to create a single floating point, or “ REAL” data tag. device operation: with Custom Add-On Profile for RSLogix 5000 (Rockwell.

It is the datatype of the destination tag specified by the COP statement that dictates the Length parameter. 7.2.2 Integrating the transmitter into a network.

Specifically, will contain the value 28836 and will contain 16709.
