In 2014, SACLA introduced a third beam line to increase the capacity of experiments. Then sophisticated control architecture needed to be developed to prevent miss operations among beamlines. In this paper, multi-host message routing in MADOCA II and its application to SALCA DAQ system to solve the problem is presented. In SACLA DAQ system, a master server was added which intermediates control messages between clients and equipment management servers. Since the access control can be centralized to the master server, reliable operation can be had by avoiding the influence by accidental modification of DAQ setting by end-users. The multi-host message routing was implemented to add an extension in MADOCA II by forwarding specific message objects to other hosts. Some technical issues related to messaging loop and time delay, are also addressed. It is also planned to utilize this technique to other cases in BL at SPring-8 where access control under firewall is required.
