4. Ensure that the controller's rotary switches are
set to the correct device address. For details
about setting a device address, see
5. Reconnect the 24 VAC supply to the controller.

Setting the device address
Metasys
equipment controllers are master devices
on MS/TP (FC or SA) buses. Before you operate
controllers on a bus, you
must
set a valid and
unique device address for each controller on the
bus. You set the CGM device address by setting the
positions of the Device Address rotary switches at
the top of the controller.
The following table describes the valid rotary
switch device addresses for communications bus
applications.
Table 9: Switch device addresses
FC Bus Communication
Mode
Valid Device Address Range
Wired MS/TP
communication
4-127
Note:
Addresses 0-3 are
reserved and not for use on
equipment controllers.
Zigbee wireless
communication
4-127
Note:
Addresses 0-3 are
reserved and not for use on
equipment controllers.
N2 communication
1-254
Note:
Addresses 0 and 255 are
reserved and not for use on
equipment controllers.
Note:
The controller
auto-detects
if the
communication protocol is wired MS/TP, Zigbee
Wireless, or N2 on the FC Bus.
The device address is a decimal address that is
set using three rotary switches. The numbers
are ordered from left to right, most significant
bit (MSB) to least significant bit (LSB) when the
controller is oriented as shown in
. In the following figure, the
switches are set to 1 2 3, designating this
controller's device address as 123.
Figure 9: Device address rotary switch block
The device address must match the device
address defined in the Controller Configuration
Tool (CCT) under
Define Hardware > Network
Settings
.
To set the device addresses on CGM controllers,
complete the following steps:
1. Set a unique and sequential device address for
each of the equipment controllers connected
on the FC or SA Bus, starting with device
address 4.
2. 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 equipment controllers do not need
to be physically connected on the bus in their
numerical device address order.
3. Write each controller's device address on the
white label below the device address rotary
switch block on the controller's cover.
Refer to the
MS/TP Communications Bus Technical Bul-
letin (LIT-12011034)
for more information about con-
troller device addresses and how to set them on
MS/TP buses.
Removing a terminal block
To remove the terminal block from the circuit board,
complete the following steps:
Note:
You need a flat blade screwdriver to
remove the terminal block.
