4. Ensure that the controller's device address DIP
switches are set to the correct device address.
For details about setting a device address, see

Setting the device address
Metasys
field controllers are master devices on an
MS/TP (SA or FC) bus. Before you operate field
controllers on a bus, you
must
set a valid and
unique device address for each controller on the
bus. You set a field controller's device address by
setting the positions of the switches on the DIP
switch block at the top of the controller. Device
addresses 4 through 127 are the valid addresses for
these controllers on an MS/TP FC Bus.
Device Address
Use on Description
0
(Switch 128 Off)
Reserved for FC Bus Supervisory
Controller(not for use on field
controllers).
1-3
(Switch 128 Off)
Reserved for peripheral
devices (not for use on field
controllers).
4 to 127
(Switch 128 Off)
Used for MSTP master devices
(field controllers) that are
hardwired to an SA bus or FC
bus.
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 must be set
to
OFF
for all hard-wired SA and FC bus applications.
Figure 9: Device address DIP switch block set to
address 21
Note:
Metasys
field controllers ship with switch
128 ON and the remainining adress switches
off rendering the controllers wired subordinate
devices, which do not operate on MS/TP
buses, but do 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 the controllers,
complete the following steps:
1. Set
all
of the switches on the address DIP
switch block (128 through 1) to OFF.
2. Set one or more of the seven address switches
(64 though 1) to ON, so that the sum of the
switch numbers set to ON equals the intended
device address. Set the highest number switch
that is less than or equal to the intended device
address to ON. Then continue setting lower
numbered switches until the total equals the
intended address. For example, if the intended
device address is 21, set switch 16 to ON first,
then set switch 4 ON, followed by switch 1
(16+4+1= 21). See Figure 9.See for valid device
addresses.
3. Set a unique and sequential device address for
each of the controllers connected on the SA or
FC bus starting with device address 4. To ensure
the best bus performance, set sequential device
addresses with no gaps in the device address
range (4, 5, 6, 7, 8, 9, and so on). The controllers
do not need to be physically connected on the
bus in their numerical device address order.
4. Write each controller's device address on the
white label below the DIP switch block on the
controller's cover.
