Setting The Device Address; Removing A Terminal Block - Johnson Controls F4-XPM Series Installation Manual

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.

Setting the device address

About this task:
FX-PC Series expansion modules are master 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.

The device address is a decimal address that is set using
three rotary switches located at the top of the expansion
module. In the following figure, the switches are set to 1 2
3, designating this expansion module's device address as
123.

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:

4-127
Note: Addresses 0-3 are
reserved and not for use on
expansion modules.

reserved and not for use on
expansion modules.
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 FX-PC Series Controllers MS/
TP Communications Bus Technical Bulletin
(LIT-12011670) 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.
2. Underneath the terminal block, in the small gap
between the bottom of the terminal block and
the circuit board, insert the flat blade of the
screwdriver.

3. To detach the left-hand side of the terminal block,
position the flat blade underneath the terminal
block to the left, and push down the screwdriver
handle. When you do this, you are using the
screwdriver as a lever to pry up the terminal block.
4. To detach the right-hand side of the terminal block,
position the flat blade underneath the terminal
block to the right, and push down the screwdriver
handle.
5. If necessary, repeat steps 3 and 4 until the terminal
block is removed.
Removing the expansion module cover
About this task:
Important: Electrostatic discharge can damage
expansion module components. Use proper
electrostatic discharge precautions during
installation, setup, and servicing to avoid damaging
the expansion module.
