I have a question regarding LonWorks and Opto 22. Has any one done any work involving integrating a LonWork system to a PAC controller? I have a particular system where there is a series of LonWorks PLC's on a network that communicate with the main PC. The PC database (i think its running Schneider TAC) is corrupt and the client is not happy with the current front-end, plus it is going cost a fortune to fix.
I have been asked if a solution is feasible based on an Opto 22 PAC system. Being LonWorks, i am thinking the best approach would be to purchase a Lon->Modbus gateway/router and use a PAC S as the interface between the HMI and I/O. I can then recommend a 2-5yr plan to slowly replace the Lon I/O with Opto 22 I/O and eventually run a full Opto 22 system.
Has anyone else done any work with LonWorks devices?? any recommendations of how to implement Lon->Opto??
