We have programmed Unitronics PLC/HMI in the past. We are assuming the Micromax is the Unitronics PLC V350. Integration with the CSC400 later on will not be an issue (it is not included in our current proposal). We have worked on steam generators in the past for local clients using GE & AB PLCs with Microsoft HMI. Since you have not specified what all has to be done in V350, we are going with your budget. We have the editor software for the PLC also. It will be good to know more about what has to be done. Also, the local distributor is in our close network & may be able to borrow a unit. We can have a small web meeting.
We are in PLC programming business since 1989 & have a lot of experience in building drivers, database, reporting, analytics, database, mobile & web applications. Hope to serve you.
