Setup and adjustments
Important: Electrostatic discharge can damage
controller components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the controller.
Configuring wireless communications
About this task:
To configure an expansion module for use with the
ZFR183x Pro Series Wireless Field Bus system, complete
the following steps:
1.
Disconnect the 24 VAC supply from the expansion
module.
2.
Wire the input/output terminals and FC bus.
Note: In wireless network applications, do
not connect any wires to the FC bus terminal
block.
3.
Important: Before the XPM expansion module
is powered on, connect the ZFR183x Pro Wireless
Field Bus Router to the FC bus port (RJ-12 modular
jack) on the front of the device.
4.
Ensure that the expansion module's rotary
switches are set to the correct device address. For
details about setting a device address, see
the device
address.
5.
Reconnect the 24 VAC supply to the expansion
module.
For more information about the ZFR Pro Wireless
Field Bus system, refer to the WRG1830/ZFR183x
Pro Series Wireless Field Bus System Technical Bulletin
(LIT-12013553).
Setting the device address
About this task:
Metasys expansion modules are manager devices on
MS/TP (FC or SA) buses. Before you operate expansion
modules on a bus, you must set a valid and unique
device address for each expansion module on the bus.
You set the XPM device address by setting the positions
of the Device Address rotary switches at the top of the
expansion module.
The following table describes the valid rotary switch
device addresses for communications bus applications.

Note: Addresses 0-3 are
reserved and not for use on
expansion modules.
4-127
Note: Addresses 0-3 are
reserved and not for use on
expansion modules.
The device address is a decimal address that is set using
three rotary switches located at the top of the expansion
module. The numbers are ordered from left to right,
100s, 10s, and 1s when the expansion module is oriented
as shown in
Physical
features. In the following figure,
the switches are set to 1 2 3, designating this expansion
module's device address as 123.
Figure 11: 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 XPM expansion modules,
complete the following steps:
1.
Set a unique and sequential device address for
each of the devices 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
devices do not need to be physically connected on
the bus in their numerical device address order.
3.
Write each expansion module's device address on
the white label below the device address rotary
switch block on the expansion module's cover.
Refer to the MS/TP Communications Bus Technical
Bulletin (LIT-12011034) for more information about
device addresses and how to set them on MS/TP
buses.
Removing a terminal block
About this task:
To remove a terminal block from the circuit board,
complete the following steps:
Note: You need a flat blade screwdriver to remove
the terminal block.
1.
To prevent any possibility of damage from an
accidental short, remove power from the
expansion module.
