MSC OLD UNITS ON BUS
If the module detects a module on the MSC link which is
incompatible with the current module, then the MSC Compatibility
alarm will be triggered. Check all the modules’ version numbers
(under About | Application Number on the modules’ displays),
modules pre V3 cannot communicate with modules V4 and
onwards. Use the DSE Configuration Suite Software to upgrade the
firmware (Tools | Update Firmware) of the older modules to V4 and
onwards.V5.0 cannot communicate with older modules and V5.1
saw a change where Dse 55xx and 75xx series communicate with
86xx range of modules, therefore all 86xx need to be at V5.0+ to
communicate on the same MSC link.
