One of key features of the event timing system in the PAL-XFEL, the beam synchronous acquisition is used in many beam diagnostics and analysis and the species of that increase gradually. In order to reduce the cost for event receivers which are required for operating the beam synchronous acquisition and to resolve the difficulty of the limited platform dependent on event receivers, we developed the virtual event receiver system receiving timestamps and BSA information from an event generator not using real event receivers. In this paper, we introduce the software architecture of the virtual event receiving system and present test results of it.
