Indus-2 is a 2.5 GeV Synchrotron Radiation Source at Indore, India. With 6 beamlines commissioned, several more under installation & commissioning and 5 insertion devices planned, the machine is operated in round the clock mode. With implementation of orbit, tune and bunch feedback systems and many new systems in planning, machine is constantly evolving and so is the control system. The control system software is based on PVSS SCADA running on windows PCs and also integrates other software modules in Labview and Matlab. The control hardware is a combination of VME based control stations interconnected over Ethernet and Profibus. Some recent system enhancements include Parameter deviation alarms, transient data capture system, database improvements and web services. Paper takes a stock of the control system and it's evolution with new systems in the offing.

Indus-2 is a Synchrotron Radiation Source. Injection energy of electron beam is 550 MeV which is raised to 2.5 GeV using Ramping process. Magnet Power Supply Control System(MPS-CS) is used to energize magnets during filling & Ramping. Part of MPS-CS that mainly caters to Ramping consists of 19 VME stations controlling 29 Power Supplies. Global data capturing rate of MPS-CS is 1 Hz that records readback of set-value,control’s reference & power supply’s output. But Ramping changes control’s reference at rates between 20-150 Hz.So a system of 1 Hz may miss out any deviation in data occurring during Ramping at higher rate. For this purpose a Synchronized Ramp-Data Capture(RDC) scheme has been incorporated in the MPS-CS which helps in capturing & analyzing any deviation in control’s reference & power-supply readback during Ramping. Using this scheme we can capture data at distributed VME stations at the rate of Ramping-clock & in a synchronized way. Main hardware consists of a 24-bit ADC board & 18-bit DAC board for each of 29 Power Supplies & a common Ramp-clock generator board. Amount of data captured in one Ramping Cycle is between 12-14 MB which is collected & transferred to User-interface.
