Setup and Adjustments

Setting the device addresses
Metasys field 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 a expansion module's device address by setting the
positions of the switches on the DIP switch block at the
top of the expansion module (Figure 1). Device addresses
4 through 127 are the valid addresses for these expansion
modules.
The DIP switch block has eight switches numbered 128,
64, 32, 16, 8, 4, 2, and 1 (Figure 9). Switches 64 through 1
are device address switches. Switch 128 is a mode switch
that enables a expansion module 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: Expansion module ships with switch 128 ON
and the remaining address switches off rendering
the expansion modules wired 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 expansion module before applying power to
the expansion module on the bus.
To set the device addresses on Metasys field
expansion modules:
1. Set all of the switches on the address DIP switch
block (128 through 1) to off.
