DSQC 679 (3HAC028357-001) is the standard FlexPendant teach pendant for ABB IRC5 robot controllers — the primary human-machine interface used for programming, jogging, monitoring, and operating all ABB industrial robots equipped with the IRC5 control system. Ordered under part number 3HAC028357-001 and designated DSQC 679, this unit replaced the previous generation 3HAC023195-001 and requires RobotWare 5.07.02 or higher for full functionality.
Weighing 3.06 kg with overall dimensions of 380 × 340 × 220 mm, it connects to the IRC5 controller via a multi-pin circular connector and provides operators with a touchscreen interface, three-position enabling device, emergency stop button, and joystick for manual axis movement.

What Is the DSQC 679 (3HAC028357-001)?
The DSQC 679 FlexPendant is the operator control unit within the ABB IRC5 robot controller ecosystem. It is the physical device through which engineers and technicians interact with ABB IRB-series robots — including the IRB 1600, IRB 2400, IRB 4400, IRB 6600, and IRB 7600 — for all programming, testing, and manual control operations.
The pendant communicates directly with the IRC5 main computer over a dedicated pendant bus, transmitting program commands, safety signals from the enabling device, and emergency stop signals in real time.
Its touchscreen is engineered for continuous operation in harsh industrial environments and is resistant to water, oil, and accidental welding splashes.
The integrated bumper housing provides mechanical protection against impacts during routine shop-floor use. The DSQC 679 is not interchangeable with FlexPendants from the IRC5 P (paint) or IRC5 Compact single-cabinet variants without confirming the cable connector type — this is a frequent source of procurement errors in multi-robot facilities.

DSQC 679 as a Replacement for DSQC 676 (3HAC023195-001) — Compatibility Notes
The DSQC 679 (3HAC028357-001) is the direct ABB-designated replacement for the DSQC 676 (3HAC023195-001). Both pendants share the same cable connector type and physical interface with the IRC5 controller cabinet, allowing direct substitution without cable modification in standard IRC5 Single Cabinet and IRC5 Compact installations.
The key prerequisite for replacement is the RobotWare version running on the IRC5 main computer: the DSQC 679 requires RobotWare 5.07.02 or higher.
Facilities running earlier RobotWare versions (5.06.xx or below) must perform a RobotWare upgrade before installing the DSQC 679, or the pendant will fail to initialise correctly and display a version incompatibility error on boot.
No mechanical modification to the controller cabinet is required. After physical connection, the IRC5 system recognises the new pendant automatically — no parameter configuration in RobotStudio is needed.
Engineers should note that the DSQC 679 is not compatible with the newer OmniCore controller generation (which uses the DSQC 1000 pendant, 3HAC050856-001); confirm the controller generation before procurement to avoid compatibility issues in mixed-generation robot cells.
Expert Installation Tips
The most common installation error with the DSQC 679 in multi-robot facilities is connecting the pendant to an IRC5 controller running a RobotWare version below 5.07.02 — always verify the RobotWare version via the ABB Service Information System or directly on the FlexPendant boot screen before ordering a replacement unit.
When connecting the pendant cable to the IRC5 controller, align the connector keying carefully before inserting — forcing a misaligned connector bends the pins inside the port and requires a full controller board replacement, which is significantly more expensive than the pendant itself. Tighten the locking ring to firm resistance only; overtightening deforms the connector housing.
In environments with welding fumes or coolant misting, inspect the touchscreen gasket seal annually — the DSQC 679 touchscreen is splash-resistant but not hermetically sealed, and degraded gaskets allow contamination ingress that causes touchscreen failures unrelated to the pendant electronics.
When storing a spare DSQC 679, keep it in the original packaging or a dedicated pendant hanger — resting the unit on its connector cable repeatedly stresses the cable entry point, which is the most common mechanical failure point in aged pendants.
Frequently Asked Questions
Q: Can the DSQC 679 (3HAC028357-001) replace a DSQC 676 (3HAC023195-001) without any software changes?
A: Only if the IRC5 controller is running RobotWare 5.07.02 or higher. If the current RobotWare version is 5.06.xx or below, a RobotWare upgrade is required before the DSQC 679 will initialise. The physical connector and cable are compatible — no mechanical modification is needed.
Q: Is the DSQC 679 compatible with the ABB OmniCore controller?
A: No. The OmniCore controller uses a different pendant generation — the DSQC 1000 (3HAC050856-001). The DSQC 679 is exclusively compatible with the IRC5 and IRC5C controller families. Connecting a DSQC 679 to an OmniCore controller will result in a non-functional pendant due to protocol incompatibility.
Q: The DSQC 679 touchscreen is unresponsive but the pendant powers on — is this a pendant failure or a controller issue?
A: In most cases this indicates a pendant-side failure, specifically either a degraded touchscreen digitiser or contamination beneath the screen gasket. Before replacing the full pendant, check whether the IRC5 FlexPendant port on the controller responds correctly when a known-good pendant is connected — if the known-good pendant also shows touchscreen issues, the fault is in the controller’s pendant interface board (typically the DSQC 679 communication port on the main computer), not the pendant itself.
