Setup and Adjustments
Setting the device address
Metasys
expansion modules are master devices on
MS/TP (SA or FC) buses. Before operating expansion
modules on a bus, you
must
set a valid and unique
device address for each expansion module on
the bus. You set an expansion module's device
address by setting the positions of the switches on
the DIP switch block at the top of the expansion
module. Device addresses 4 through 127 are the
valid addresses for these expansion modules.
The following table describes the FC bus and SA
bus device addresses for Johnson Controls MS/TP
communications bus applications:
