Q
Core Settings Options Available on Intel 12th Generation CPUs
A
The number of P-Cores and E-Cores may vary depending on PC specifications, so please use the core settings below in conceptual terms.
 
Example)

• Intel Core i7-12700 specification with 8 PCores and 4 ECores
• Default clock base of 2.1 Ghz for P-Core and 1.6 Ghz for E-Core

[Uptility according to the above options]

 

Option 1) Utilizing P-Core in the WMX Engine can improve the performance of the WMX Engine the most, and since Hyper Threading and E-Core are not used, the system stability is the most, but the resource utilization on the PC is limited.


=> Actual number of cores set for Windows and RTX: Windows Core 7, RTX Core 1



 

Option 2) Utilize Hyper Threading, but with limited Windows Core allocation (allocating only 14 Windows), it provides maximum resource allocation to user applications while keeping separate RTX Core threads away from the Windows side. 

However, the Hyper Threading option makes the system less reliable than when not in use.


=> Actual number of cores set for Windows and RTX: Windows Core 14, RTX Core 1 (or 2)




Option 3) The WMX Engine uses E-Core based on architecture that has changed since Intel's 12th generation, all P-Core resources are assigned to the user application, and WMX uses E-Core, which can be proposed when the user application needs a lot of computing power.

However, the system stability is relatively lower than the above two options, and the WMX Engine's processing performance is reduced by about 10-20%.


=> Actual number of cores set for Windows and RTX: Windows Core 16, RTX Core 1 (or 2)


 

Overall, the more system resources you use, the less reliable you are, and to increase system stability, you need to limit variable resource utilization capabilities such as hybrid architecture and Hyper Threading to increase system stability.



 

Q
How do I solve the WMX manual when I download it and I don't see the content?
A
The content may not be visible due to each user's PC settings.

After downloading, check 'Unblock' in File Properties-General Tab-Security Item.

Q
Maximum cable length
A
The physical layer of EtherCAT is Eternet, so the hardware specification is the same.
The cable length limit between each node is up to 100M, which is why the physical layer of most recently developed field buses is based on Ethernet.

However, even if the physical specification is 100M, these long cables can cause large transmission times and cause synchronization problems when using the DC Sync feature of the EhterCAT.
Q
What is a communication Jitter?
A
Communication jittering refers to a temporal wobble in real-time conditions. For example, when a Slave needs to execute an instruction exactly in a periodic cycle, it can deviate from the reference time. This results in a temporal jitter of +1 or -1 (or more), which is called a communication jitter. There are several reasons for the occurrence of jittering, but the main influencing factors are noise, Slave's CPU clock unevenness, and the mismatch in transmission speed due to the length of the cable.
Q
Do you want to assign one code from RTX?
A
Recently, the software technique has remained the same, but the hardware level of PC is greatly improving.
Recent hardware CPUs typically involve quad-core processing of common equipment sequences and UIs, leaving more resources. As software techniques have not yet advanced in parallel processing these multicores, resources on PCs running most equipment programs account for 15 to 30 percent of the total resources.
In this situation, when one core is assigned and processed in RTX, it becomes a completely separate parallel process, but when two or three more cores are assigned to RTX and implemented separately for each role, it also enables multi-controllers that make the most of their hardware.                                                                                                  
For example, based on the quad core, the first core is a sequence of equipment, the second core is motion-only, the third core is vision-processed, and the fourth is GUI-processed, and the hardware of the PC of the equipment can be 100% displayed.
Q
Real-Time Jittering?
A
The real-time system we use is a product from IntervalZero in the United States, which is also certified by Microsoft.
It has a category of hard real-time with a high-priority real-time task processing that uses the CPU (core) in a completely destructive manner and independently of any Windows process.
(Hard Real-time: a system that maintains a set DeadLine unconditionally)
RTX also has a separate, independent Hardware Abstract Layer (HAL), which allocates an independent CPU core that Windows cannot engage with to handle the tasks.
WMX is a soft motion engine based on this, and since 2005, it has accumulated know-how on programs in real time, making the best use of it.
Q
ESI (EtherCAT Slave Information) ? ENI (EtherCAT Network Information) ?
A
The EtherCAT master requires an EtherCAT Slave Information (ESI) file that is defined for each Slave to recognize the slave and make the correct settings.
The file is provided by the Slave manufacturer and is available in xml format.
Most EtherCAT masters can read these ESI files to set up or communicate with Slave.

In this process, WMX must create a separate ENI file based on the ESI file, and the ENI file can be easily created through the WMX utility (EcConfigurator) provided by us.
Q
Communication cycle range provided by WMX
A
To date, the communication cycles provided by WMX are 0.125ms, 0.25ms, 0.5ms, 1ms, 2ms, and 4ms.
However, there is a limit to the maximum number of Slaves that can be processed for each communication cycle.
(e.g., 128 axes per 1 ms of communication cycle)
Q
Soft motion control precision (compared to motion-only controllers)
A
WMX is a flexible, diverse motion sequence controller that is controlled by communicative profiling.
Unlike motion controllers such as ACS and UMAC, which directly control the motor through the upper Gain, the WMX does not have the upper Gain and controls the respective servo drivers in a communication profiling manner.
Up until 10 years ago, most of the servo drivers were controlled in a low control period and pulse-wise manner, so controlling directly from a higher motion controller than a servo driver was suitable for high-precision control.
However, recent breakthroughs in servo drivers have significantly improved motor control cycles, and various tuning gains provide greater close-loop functionality than direct control from the top.
(Additionally, the servo driver's Full-Close Loop function provides a real robot position-based close-loop function.)
In addition, utilities provided by servo driver companies are more specialized in motor management and provide advanced tuning functions.
As the control precision of the servo driver is in full swing, our small port motion product is able to synchronize many axes with the advantage of high-precision high-speed control and communication method.
Q
Soft Motion and General Controller (Board, StandAlone Type) Differences
A
Most controllers are PC-based motion board types and StandAlone types.
Motion Board Type is easily installed and most commonly used,
Due to the nature of the hardware, there are many performance limitations due to the limitations of memory size and MCU throughput.
(For example, restrictions on the number of axons or communication cycles that can be controlled, restrictions on registration of special features, etc.)
For the StandAlone Type, high performance and high definition are good, and for some of our professional features, we're talking about our products and
Performance is so good that it is difficult to compare the advantages, but it has high prices, lack of professional technical support (foreign products),
As a separate hardware, there are difficulties in sharing resources with the main program.

Our product is a PC-based EtherCAT motion master platform that ensures real-time, affordable,
Rich resources using PC resources, fast and easy updates, easy integration with main programs,
It is differentiated in many advantages such as the use of various hardware.
Q
After WMX installation, how does it affect the installation PC?
A
Depending on your planned or used servo platform and interface, some features on your PC may need to be disabled due to IRQ conflicts due to hardware and software configurations. 

The PC adapter card's PCI slot location, USB, Ethernet, sound, etc. are required to be disabled.
Q
Need a separate PC expansion slot for EtherCAT?
A
If your PC Network Interface Card (NIC) is compatible with our product, WMX, no separate slot is required. 
Please check the list of NICs that are compatible with WMX.

If you are not using a compatible NIC, you may need PCIe or PCI slots, depending on your PC specifications.
Compatible NIC lists can be found through the online manual.
*PCIe type NIC is recommended.
