Hello everyone, I am currently working on integrating a system with a SICK safety controller, specifically the SICK Flexi Soft main module FX3-CPU3 along with various extension I/O modules. Upon generating a safety report, I have identified a recurring issue related to Extension module 2: FLEXBUS+ communication being disturbed. This could potentially be due to EMC disturbance. I have also observed occasional failures in the controller when resetting the safety circuit in the cell, indicated by flashing red LEDs on the CPU and other modules. Is there a connection between these issues? Thank you for your insights.
Are you experiencing high levels of electromagnetic interference in your vicinity? This could be caused by various sources such as power lines, radio and TV signals, wireless devices, switching power supplies, and microwave ovens. Additionally, running low voltage or DC wires alongside 120VAC or higher voltage levels in the same conduit may also result in electromagnetic compatibility (EMC) disturbances.
AustinC1 inquired about the presence of electromagnetic interference in the vicinity, which could stem from various sources like power lines, radio and TV broadcast signals, wireless devices, switching power supplies, and microwave ovens. It's crucial to avoid running low voltage or DC wires in the same conduit as 120VAC or higher voltage levels, as this could lead to EMC disturbance. Given that it's a shop floor, there is a likelihood of encountering such interferences in the area.
Your problems with the Extension module 2 and the CPU could indeed be related. The FLEXBUS+ communication disturbance might be causing a cascading issue, affecting the CPU's ability to reset the safety circuit effectively. EMC disturbance often affects communication between modules, so it could potentially cause a variety of issues. It might be helpful to assess your EMC compliance for any potential inconsistencies. I'd recommend isolating both issues to confirm if they are indeed linked. Don't forget to check your grounding and wiring conditions as well, as they immensely affect the system's EMC performance.
It sounds like you're dealing with a tricky situation! EMC disturbances can definitely impact communication on the FlexBus, and it’s not uncommon for issues like this to affect the stability of the whole system—including the controller's ability to reset correctly. Have you tried checking the grounding and shielding of the cables connected to your extension module? Sometimes even slight changes in layout or shielding can make a big difference in EMC susceptibility. Also, reviewing the placement of your safety controller and any nearby equipment might help identify potential interference sources. It's worth investigating further to see if addressing the communication errors helps with the controller failure too! Good luck!
It sounds like you're dealing with a challenging setup! The communication disturbances on the FLEXBUS+ could very well be tied to EMC issues, especially if your setup is near heavy machinery or other sources of electrical noise. Ensuring that your wiring is properly shielded and routed away from potential interference could help. As for the flashing red LEDs during circuit resets, that could indicate a failure mode triggered by the communication issues or might be related to insufficient power supply during the reset process. Double-checking your power integrity and grounding might also provide some clarity. Have you tried conducting an EMC assessment to pinpoint the source of the interference?
