| Abstract |
The migration of the controls system for the ISIS accelerator from Vsystem to EPICS presents a significant challenge and risk to day-to-day operations. To minimise this impact throughout the transition, a software bridge between the two control systems has been developed that allows the phased porting of HMIs and hardware. The hybrid Vsystem and EPICS system also allows the continued use of existing feedback control applications that now require interaction between both control systems, for example the halo steering operation in Target Station 1. This work describes the implementation of this bridge, referred to as PVEcho, for the mapping of Vsystem channels to EPICS PVs and vice versa. The position within the wider ISIS controls software stack is outlined as well as how it utilises Python libraries for EPICS. Finally, we will discuss the software development practices applied that have allowed the bridge to run reliably for months at a time.
