Browser-based software may allow engineers to add control functionality on input/output devices, potentially allowing some decisions to move outside of factory-floor control panels and directly onto machines.

New software turns I/O devices into field level logic controllers. Image source: TurckAutomation supplier Turck says the field logic control technology could lower control costs for manufacturers — especially targeted small and mid-size operations — because it can augment control capabilities without investing in new programmable logical controllers or upgrading existing PLCs.

Turck says the product also allows flexibility because it permits setting conditions for actions to be carried out locally by I/O devices on individual machines. I/O devices turned into field logic controllers can be used in multiple ways, the company says: as a standalone control system (without a PLC); as backup for a PLC; or as partner with the PLC. In the latter case, the FLC can be used to monitor manufacturing operation and send data and updates to the PLC.

Functions that can be added through the software include use of timers and counters, arithmetic calculations, program monitoring, and communications with other controllers.
