45DN Bus Expansion Cards

For use with Q45X Photoelectric Sensors on DeviceNet™ Bus Networks

Printed in USA 05/03 P/N 39667 rev. C

• Banner model 45DN plug-in bus cards enable a Banner Q45X Series sensor to
establish a logical relationship between the sensor’s output and other compatible
devices on a DeviceNet™ bus network.

• The following features of the 45DN are programmable via the network with a
configuration tool*:

Feature Range (default)

Network Address 0-63 (63)
Baud Rate 125K, 250K, 500K (125K)
Operate Mode** Light Operate or Dark Operate (Light Operate)

All 45DNs support the following connection type:

The Explicit Message Connection, which is required to Set and Get sensor
Attributes.

The 45DN1 supports the following connection type:

The Bit Strobe Connection, which responds to a master’s request.

The 45DN2 supports the following connection type:

The Change of State Connection, which responds to the slave’s change of state.

I/O Response (8-bit word of data):

Bit 0: 0 Output is OFF

1 Output is ON

Bit 1: 0 Alarm is OFF

1 Alarm is ON

Bits 2-7 Not used: always 0

* Configuration may be simplified through use of an Electronic Data Sheet (Banner

model EDS 40223)

** The Light/Dark Operate switch in the Q45 sensor must be set to the Light Operate

position (the factory setting).

WARNING . . .

Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A
sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner Safety Products
catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

The 45DN is one of a family of bus expansion cards for Q45X Series sensors which
includes models for use on AS-Interface, SDS

™

, and DeviceNet.

Use of a 45DN bus expansion card turns the Q45X into a “smart” sensor which can
be connected to a DeviceNet bus network using a simple “dumb drop” junction box or
a “T” connector. Plugging a bus expansion card into a Q45X Series sensor
automatically converts the basic sensor outputs to a pair of datacom connections with
the proper protocol for use on a DeviceNet bus network. Q45X sensors without bus
cards (i. e. “dumb sensors”) may also be added to any bus system, via a “smart
drop” junction box. Basic Q45X sensors (without bus expansion cards) interface
directly to PLC dc inputs. The block diagram below illustrates how “smart” and
“dumb” Q45X Series sensors can be mixed together on the same bus network.

Installation and Removal

Modules are installed through the top of the sensor, as follows:

1) Remove power from the sensor.

2) Loosen the top cover hold-down screw and raise the cover. The cover is hinged at
the front.

3) Using a small screwdriver inserted into one of the slots at the rear of the inside
black cover, lift up and remove the black inside cover (Figure 2A).

4) Insert the card in the expansion slot so that the connector receptacles on the card
align with the connector pins inside the sensor. Slide the card down into the slot
until the connectors are fully engaged (Figure 2B).

5) Replace the original black inside cover with the one supplied with the 45DN card.

6) Make sure that the Light/Dark Operate switch in the Q45X sensor is set to the
Light Operate position.

Modules are removed through the top of the sensor, as follows:

1) Follow steps 1 through 3 of the installation procedure, above.

2) Insert a small, flat bladed screwdriver or similar tool into the lift slot on the edge
of the expansion card (Figure 2C). Gently pry up to disconnect the card, and then
lift it out.

3) Replace the black inside cover.
