TX-I/O

™ is a line of I/O modules with associated power and communication modules
for use within the TALON system. The I/O modules reside on the TX-I/O
which simultaneously carries the supply voltages for the I/O modules and the field
devices and provides communication bus between the island bus controller and the
connected TX-I/O modules.

TX-I/O island bus communication requires one of the following controllers:

 TC Modular
 TC-36

TX-I/O Product Range Overview

island bus

,

TC Modular

 The TC Modular connects to the island bus through a TX-I/O Power Supply or TX-

I/O Bus Connection Module using standard DIN rails.

 The TC Modular provides the control database and communications for points on

TX-I/O modules, but it does not supply power.

TC-36

 The TC-36 connects to the island bus through a TX-I/O Power Supply or TX-I/O

Bus Connection Module using island bus connectors.

 The TC-36 provides the control database and communications for points on TX-I/O

modules, but it does not supply power.

TX-I/O Modules

TX-I/O Modules

TX-I/O Modules are modular expansion I/O consisting of an electronics module and a
terminal base; they receive power from a TX-I/O Power Supply or Bus Connection
Module.

 The electronics module performs A/D or D/A conversion, signal processing, point

monitoring, and command output.

 The terminal base provides for termination of field wiring and connection of the self-

forming TX-I/O island bus.

The design of the TX-I/O Modules provides optimum diagnostics and results in a more
efficient installation and maintenance workflow.

 Field wiring may be terminated prior to installation of electronics.
 Connected peripheral devices can be measured without affecting or being affected

by the I/O module.



Hot-swappable electronic components

allow powered electronics to be
disconnected and replaced without removing terminal wiring or disturbing the self­forming bus.

Local Override Feature

Do not use the local override for safety shutdown operations, such as performing
service or maintenance. Use suitable emergency switches instead.

The local override feature is only available on certain I/O modules.

 In principle, plug-in I/O modules with and without a local LCD panel/operator

 Only outputs can be overwritten. Any attempt to overwrite an input results in an

 Local override also operates without a bus master, provided that the 24 Vdc

and they are permanently saved in the module.

Override Button

Pressing an override button in the middle enables or disables the local override (press
until the override status LED changes to ON or OFF).

When local override is enabled:

 Pressing "+" increases an output value or activates the relay.
 Pressing "–" reduces an output value or disables the relay.
 Repeated or sustained pressure changes the value by several stages until the

function stops at the highest/lowest stage.

 The I/O status LED and LCD display change accordingly.

Pressing "+" or "–" when local override is disabled results in an error.

Address Keys

I/O modules are addressed using a TX-I/O address key.

TX-I/O Address Keys.

The keys are available in sets of 24, up to a maximum value of 72 (2 sets of 12, 1-24,
25-48, and 49-72).

 The I/O module address is mechanically encoded in the address key.

‒ Without an address key, the module is inactive.
‒ With an address key inserted, the module has full functionality.

 Based on the address, the TC Modular or TC-36 configures the I/O module,

indicates which field devices are connected to this module, and which function is
required for the field devices.

CAUTION
The address key must be inserted firmly into the terminal base before swiveling it
into the plug-in module.

When the address key is swiveled out, the I/O module is inactive, and it cannot be
overridden locally. The state (automatic operation, tool override, or local override),
configuration, and parameters of the individual I/O points are saved in the non-volatile
memory of the plug-in module.

Swiveling the Address Key Back into Place

When a fault is repaired or an address key is swiveled back into place, operation
resumes in the same state as before (automatic operation, tool override, or local
override). The process values are only stored in tool override or local override.

Separating a Module from its Terminal Base.

To Park a Module

In the "parked" position the plug-in modules are fully isolated from the terminal bases.
The connected field devices can be measured through the test pickups without being
affected by the plug-in module electronics.

1. Squeeze module sides above the disengage catch and pull up slightly to disengage
the I/O module from the terminal base.

2. The I/O module is retained in the terminal base (‘parked’), but all wiring
connections are now floating.

To Remove a Module

Squeeze module sides above the release catch and pull up to remove the I/O module
from the terminal base.
