We are doing a PLC5 to ControlLogix upgrade, and can't figure out how to setup the data in the block transfer to allow floating point values to be read on a Standard PanelView. Any suggestions or samples would be appreciated. Rockwell tech support has not been helpful to this point. |

We originally passed the Analog Input Data using Block Transfers directly from the PLC 5 Analog Point as a Raw Value to the ControlLogix Controller. You can receive the Raw Input as a Decimal or BCD Value depending on the Configuration Settings. We then scaled the Raw Input using a Scaling Input AOI as we would any hardwired Analog Input. As far as displaying the number on the Standard PanelView. The only suggestions I can come up with is to verify that Floating Point option is selected in PanelBuilder32 Software, and that your data path is correctly setup under the communication path in PB32. You could also try to multiply the values in the PLC by 10 and Scaling the HMI Tag by .1 Hope some of that information will be useful. Google Search - Standard PanelView Floating Point (MrPLC.com had a similar issue) Yes, I recall the good old days when we had to scale integers in the PLC, send the value to the HMI, then divide to display decimals.
