Setup and Adjustments
Setting the device addresses
Metasys
field controllers are master devices on MS/
®
TP (SA or FC) buses. Before operating controllers
on a bus, you must set a valid and unique device
address for each controller on the bus. You set a
controller's device address by setting the positions
of the switches on the DIP switch block at the top
of the controller (Figure 10). Device addresses
4 through 127 are the valid addresses for these
controllers.
The DIP switch block has eight switches numbered
128, 64, 32, 16, 8, 4, 2, and 1. Switches 64 through 1
are device address switches. Switch 128 is a mode
switch that enables a controller to operate on a
ZFR/ZFR Pro Series Wireless Field Bus. Switch 128
must be set to Off for all hard-wired SA and FC bus
applications. Set switch 128 to ON for wireless FC
bus applications only.

Note: Metasys field controllers ship with switch
128 ON and the remaining address switches
off rendering the controllers wired subordinate
devices, which do not operate on MS/TP buses,
but will not interfere with bus operation.
Set a valid and unique device address on
the controller before applying power to the
controller on the bus.
To set the device addresses on Metasys field
controllers:
1.
Set all of the switches on the address DIP
switch block (128 through 1) to Off.
