Stuart had flagged that the h1susmc2 model did not have the proper ISI->SUS IPC inputs H1:ISI-HAM3_2_SUS_GS13_* (*=X,Y,RZ,Z,RX,RY), so I added them. 

The h1suspr2 model had already been receiving these signals from h1isiham3, so there was no need to add them on the ISI side. 

EPICS error channels H1:SUS-MC2_ISI2SUS_GS13_*_IPCERR had previously been defined, so there was no need to add them, just connect them up, which meant no need to restart the DAQ.
