Pneumatic systems are an essential part of many process plants, but these machines are often stand-alone and are not connected back to the process control architecture.
In 2016, Emerson introduced electronic marshalling for pneumatic systems. This solution enables users to easily integrate the ASCO Numatics 580 Series valve islands, with Emerson’s DeltaV control system for a complete Emerson Automation I/O and pneumatics system solution for process plants.
Electronic Marshalling does away with the manual and labour-intensive practise of cross marshalling. The cables from the field are still wired in to the marshalling cabinet, but from there on the connections to the controllers are handled electronically. It is now possible to map each I/O channel to any controller.
Emerson manages this mapping with their CHARMs (CHARacterisation Modules). These are essentially analogue to digital conversion cards that may be characterised to perform any signal function.
The 580 Series CHARMs allows control engineers and project managers working on continuous and batch-oriented manufacturing projects a cost saving approach to the integration of pneumatic systems within the process control environment. The node facilitates single connection from the field to Emerson’s DeltaV™ DCS offering Electronic Marshalling, native configuration and diagnostics.
The 580 CHARMs node interfaces with ASCO Numatics 500 Series valve islands. These plug-in directional control valves help minimize system costs.
