SKF MB4150g5 Disk Chopper Controllers
Wiki > The Backend System > Specific Device IOC > Choppers > SKF MB4150g5 Chopper
These controllers are a development of the MB350g3 previously used on LET for its disk choppers and now repurposed on EMMA for its Fermi. The G5 is an Ethernet device using a MODBUS protocol to communicate, and are generally installed on the instrument private networks.
There are currently three controllers on LET (original choppers 3 & 4, and now 5) and five on IMAT (two double-disk choppers and a T0).
LET - These controllers have been allocated addresses in the range xxx.xxx.xxx.8x, which is under the control of the Experimental Controls Group. Since installation, the addresses were in the original range of xxx.xxx.xxx.18x, but problems were encountered when installing two additional controllers (see ticket 5033 for details).
IMAT - These controllers are still in the original range of xxx.xxx.xxx.18x, but it is planned to reallocate them in the interests of conformity.
