Integrated I/O and Communication: The module's standout feature is its "packaged" design, which combines a controller, power supply, 16 discrete inputs, 16 discrete outputs, 4 analog inputs, and 2 analog outputs in a single unit . It further integrates dual serial ports (RS-232/485) for DF1 and DH-485 protocols, as well as a built-in DeviceNet scanner port for network communication . This reduces the need for multiple separate modules and simplifies system architecture.
Flexible Communication: The dual serial ports allow for connection to a variety of devices, such as PanelView Plus terminals, drives, and other serial equipment, providing flexible integration options . The DeviceNet port enables direct connection to a DeviceNet network for distributed I/O and device control .
Comprehensive Control Capability: As a Logix controller, it uses the same RSLogix 5000 programming software and tag-based data model as other ControlLogix and CompactLogix controllers . This ensures a consistent programming experience and supports common control functions like ladder logic, structured text, and function block diagrams.
The 1769-L23-QBFC1B is well-suited for small to medium-sized applications that require a compact, cost-effective solution with integrated I/O and serial communication, including:
Standalone Machine Control: Controlling packaging machines, labeling equipment, and simple conveyor systems.
Legacy System Integration: Interfacing with older serial devices or HMIs using the built-in RS-232/485 ports.
Distributed Control: Acting as a DeviceNet master to coordinate multiple sensors, actuators, and drives on a DeviceNet network .
Q1: What is the difference between 1769-L23-QBFC1B and 1769-L23E-QBFC1B?
A: The key difference is the presence of an Ethernet port. The 1769-L23E-QBFC1B includes an integrated EtherNet/IP port, while the 1769-L23-QBFC1B does not . The "QBFC1B" model relies on its dual serial ports and DeviceNet port for communication .
Q2: What programming software is required for this controller?
A: It requires RSLogix 5000 software, version 16 or later . It is not compatible with newer Studio 5000 software without the appropriate firmware.
Q3: What is the maximum backplane current available for expansion modules?
A: The controller provides 800 mA of 5V DC bus current for powering additional 1769 I/O modules connected to it . This is a critical limitation when adding expansion modules or high-power communication cards.
Q4: Does the module support hot-swapping of I/O modules?
A: The 1769 CompactLogix series allows for online insertion and removal (RIUP) of I/O modules, but specific capabilities depend on the controller firmware and RSLinx software version . Refer to the controller's user manual for exact procedures.
Q5: What type of battery does the controller use?
A: The controller uses a 1769-BA or equivalent 3.0V lithium battery (CR14250SE) for real-time clock backup and program retention . The battery has an estimated life that can be monitored via the programming software .
The 1769-L23-QBFC1B is part of the 1769 CompactLogix packaged controller family. Below are key related models and accessories for different application needs:
| Product/Model | Type | Brief Description |
|---|---|---|
| 1769-L23-QBFC1B | Packaged Controller | The featured model: controller with power supply, 16/16 DIO, 4/2 AIO, and dual serial + DeviceNet ports . |
| 1769-L23E-QBFC1B | Packaged Controller with Ethernet | Similar to the featured model, but includes an integrated EtherNet/IP port for network connectivity . |
| 1769-L23E-QB1B | Packaged Controller with Ethernet | A version with digital I/O only (no analog I/O) and an EtherNet/IP port . |
| 1769-ECR | End Cap | The required right end cap/terminator for the 1769 I/O bus, included with the packaged controller but needed for expansion . |
| 1769-BA | Battery | Replacement battery for the controller . |
| 1769-PA2 | Power Supply | An additional power supply for the 1769 backplane if the controller's internal supply is insufficient for expansion modules. |
For applications needing Ethernet: The 1769-L23E-QBFC1B is recommended, as it provides the same I/O and features but with an integrated EtherNet/IP port .
For purely discrete control: The 1769-L23E-QB1B offers digital I/O only, which may be more cost-effective if analog capabilities are not required .
For expansion beyond the controller's capacity: An external power supply, such as the 1769-PA2, or a power supply module may be required to support additional I/O modules beyond the controller's internal power rating.
