I/O Configuration

  • Module icons in the I/O Configuration folder change to indicate the module has faulted or the connection to the module has been interrupted.
  • To remove a yellow triangle warning symbol, first check the connection status. If the status is "Connection is not scheduled", re-open the RSNetWorx software. Return to RSLogix 5000 software and the yellow triangle should be gone.
  • To easily find a module in the Select Module Type dialog, simply start typing any part of the module name or description. When you start typing, the Find Module dialog is launched automatically.
  • Use rack optimized communication formats for digital I/O modules to minimize amount of controller memory and communications overhead associated with these modules.
  • RSLogix 5000 automatically creates controller tags when you create an input or output module. You can reference these tags directly in your logic.
  • Use alias tags to assign names to specific input/output data and/or to provide a short alternative to lengthy structure member names.
  • When you configure an analog I/O module, hold the shift key as you move the slider to increment HH, H, L, and LL values in whole numbers.
  • Copy I/O data to a User-Defined Type (UDT) so you can synchronize I/O data with program scan. The UDT also enables easier mapping of physical I/O.

By merely opening the RSNetworx software the triangle should be gone? There's more to it than that.

"Use rack optimized communication formats for digital I/O modules to minimize amount of controller memory and communications overhead associated with these modules."

But understand that status and point-level diagnostic information will not be available in the Controller Tags collection even if the I/O modules are of the diagnostic variety.

"•Copy I/O data to a User-Defined Type (UDT) so you can synchronize I/O data with program scan. The UDT also enables easier mapping of physical I/O."

And I would add, address ONLY the UDT I/O members in logic (or aliases to the UDT members) instead of the physical I/O OR aliases to the physical I/O UNLESS an Immediate I/O condition/status for particular I/O points is desired.
