Main Programming Modes and Methods in Comau PDL2
Comau robots controlled using PDL2 can be programmed in several ways, from direct code editing via an operator panel to comprehensive simulation environments that make it possible to refine even the most complex sequences without interrupting production. At NexaRob, we use these methods depending on application complexity, quality-control needs, and the need to respond quickly to changes on the line. Below we present the key modes and tools that together enable the creation of flexible, scalable, and safe applications:
Teach Pendant (Online Programming)
- Direct Interaction with the Robot: The operator can enter PDL2 commands, define movement points, or test short sequences directly on the pendant (operator panel) at the robot.
- Ideal for Quick Corrections: When individual parameters need to be modified, such as movement speed or gripper position, a Teach Pendant helps avoid time-consuming shutdowns and switching of the entire application.
- Potential limitations: For long or highly complex sequences, such as dozens of motion points or advanced logic integrating vision inspection systems, using only the pendant may be insufficient. In such cases, we recommend offline tools or remote access.
Offline Programming (Simulation Environment)
- Working on a computer: PDL2 code created and modified in a simulation environment enables precise trajectory verification and collision analysis without interrupting the currently operating production line.
- Greater Control and Optimization: NexaRob engineers can refine cycle times, safety parameters, or cooperation with other devices (for example, feeders), minimizing the risk of errors during commissioning in the actual environment.
- Use in complex projects: Very useful in processes requiring precise analysis of every movement point, such as electronic component assembly or welding automotive parts with non-standard shapes.
Remote Online Programming, Network-Based Control
- Remote access to the Comau robot: With proper network security, NexaRob specialists or your engineering team can connect to the robot controller over the internet and update code in real time.
- Technical Support from Anywhere: This mode enables immediate support in the event of unexpected problems, failures or the need to optimize code. It does not require an engineer to be physically present at the facility.
- Cost and Time Savings: Instead of bringing experts on site, code corrections or improvements can be implemented almost immediately, minimizing production downtime.
Hybrid Approach
- Combining different methods: In practice, most companies use the Teach Pendant for corrections and quick adjustments, while offline tools are used for more extensive trajectory or control logic modifications.
- Continuous improvement: By introducing changes iteratively, partly in simulation tools and partly directly on the robot, process efficiency and quality can be improved progressively without large one-off periods of downtime.

This industry is characterized by very tight dimensional tolerances and high expectations for final-product reliability. Thanks to integrated motion-control functions and communication with force sensors, Comau PDL2 proved to be an effective solution for handling multi-stage tasks efficiently.
Context and Key Challenges
- Small Component Dimensions: Each component required extremely precise positioning, and even slight gripper vibration could damage the part.
- Continuous model variability: The plant produced a wide range of components, which required rapid application switching and frequent modifications to the control code.
- High quality and short cycle time: With a significant production volume, every second had a major impact over weeks or months, while the margin for error had to remain minimal.
Key Solutions in PDL2 Code
Modular Architecture
NexaRob prepared the application by dividing it into independent procedures (e.g. loading a component, placing it in a fixture, vision verification), while parameters (speeds, currents, force limits) were separated into configuration files. As a result, changing the product model required editing only a few values, without rewriting the code from scratch.
Integration with Force Sensors
The robot monitored pressing force in real time, which helped avoid crushing delicate circuit pins. If the configured threshold was exceeded, movement was stopped and an appropriate message was sent to the operator.
Camera for Position Verification
The vision system provided information about possible shifts of a component in its fixture, while the PDL2 application corrected the trajectory on the fly, reducing the rate of assembly errors.
Results and Benefits
- 20-30% Increase in Efficiency: Comau robots gained the ability to adapt quickly to different product variants, while automatic motion corrections reduced the time required for manual adjustments.
- Reduction of Defective Units: Precise force control and visual verification reduced the number of damaged components, lowering costs over the long term and improving the supplier's reputation.

Yes. Simulation tools are available that allow applications to be created and verified outside the real environment. This makes it possible to eliminate many potential errors before the robot is first started on the line, reducing downtime and the cost of corrections.
PDL2 supports communication protocols that allow Comau robots to dynamically correct motion based on data from vision systems or sensors. In practice, this means the robot can change its trajectory in real time, adapting to the position and shape of parts or to required contact-force parameters.
These are typically industrial robots, so protective zones such as light curtains and safety scanners are usually required. However, PDL2 itself can define speed limits and force parameters, increasing safety. NexaRob helps select appropriate occupational health and safety solutions so that human-machine cooperation is as efficient and safe as possible.
It depends on the dynamics of the production process. If processes or product ranges change frequently, code updates will be regular. On stable lines, modifications may occur occasionally, for example to optimize movement or adapt to new industry standards.
Migration may require analysis of differences in syntax and approaches to motion. At NexaRob, we have experience with such transitions. We help identify fragments that can be adapted almost directly and those that require redesign. This makes the entire process faster and easier.
