Post by ryusoup on 'keep last value' option in CODESYS EtherCAT ^{CODESYS Forge talk (Post)}
Hello, I’m using CODESYS EtherCAT Master on a Raspberry Pi controller with several remote I/O modules. I’m facing an issue where the input values from the remote I/Os drop to 0 when a connection error occurs. Is there a way to configure a “keep last value” behavior (i.e., hold the last valid input) instead of defaulting to 0 on communication loss? Best regards,

Post by yang123 on EtherCAT Can't reconnect to servo drive ^{CODESYS Forge talk (Post)}
I am using Ethercat Master 4.6.0.0 and have use the automatic restart slaves feature. But we found of after the Ethercat communication normal and slave drive power-off and power-on the slave can't reconnect sucess. The PLC Log show the drive was al status "6#34 : Invalid DC Timeout Error" and its was reconnection sucess first but seconced later the drive will show the "16#2C : Fatal Sync error" and then drive will can't reconnection. Other slave are reconnect sucess which was link after the can't reconnect's drive the drive was OMRON R88D-1SN

Post by mrkm-dic on CODESYS: Combining Master Redundancy with EtherCAT Ring Topology – Is it Supported? ^{CODESYS Forge talk (Post)}
Hello, I would like to ask whether it is technically supported (and practically achievable) to combine CODESYS Master Redundancy with EtherCAT ring (loop) redundancy in the same system. System setup CODESYS version: CODESYS 3.5.21.40 CODESYS Control SL for Weidmuller u-OS-4.12.2.0 Controllers (Masters): Weidmuller UC20-M4000 ×2, configured as Active / Standby using CODESYS redundancy EtherCAT Slaves: Weidmuller UR20-FBC-EC ×3, supporting EtherCAT ring / line break detection Topology: EtherCAT ring (loop) Main question Is it officially supported to use: ・CODESYS PLC/Master redundancy (Active/Standby) and ・EtherCAT ring topology (for cable redundancy) at the same time? Expected behavior Our expectation is: ・When the Active PLC fails, the Standby PLC becomes Active ・The Standby PLC then takes over the role of EtherCAT Master ・EtherCAT communication is re-established ・I/O control continues after reinitialization (a short interruption is acceptable; no strict bumpless requirement) We do not expect completely seamless / zero-cycle switchover, but we want to understand: ・Whether this combination is supported by design ・Or whether there are known limitations or restrictions when EtherCAT ring mode is used together with Master redundancy Clarification At this stage, the question is mainly about feasibility and support, not about a specific error message yet. Any official guidance, limitations, or real-world experience would be greatly appreciated. Thank you in advance.

Scan from "IP-Configuration" with PC connected to first EtherCAT slave and "EtherCAT" tick box ticked gives slave info. As does ticking the "Emergency" tickbox.

Post by gseidel on Scara3 kinematic robot error ^{CODESYS Forge talk (Post)}
Hi aniket-b, this error has nothing to do with the scara3 kinematics, or robotics, or SoftMotion. It means that the EtherCAT bus is not synchronized. The usual cause is that the realtime of the PLC is not sufficient. See https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html for details and ways to solve the problem. You can also check the PLC log for additional information about the error. Best regards, Georg

Post by rmaas on Fieldbus has lost synchronicity ^{CODESYS Forge talk (Post)}
Hi, On a gantry system with 2 axis i am getting the following error: SMC_DI_FIELDBUS_LOST_SYNCRONICITY This happens random, sometimes it happens every 5 minutes and sometimes no error for 2 hours... The Setup: - Using codesys 3.5 SP20 with all latest libs... - Kontron AL Pi-Tron CM4 with Preempt realtime patch (Raspberry Pi 4) - Codesys runtime 4.11.0.0 (single core) - CODESYS Control for Raspberry Pi SL licensed - Softmotion + CNC + Robotics licensed - 2x Leadshine EL8-EC400 servo drives - Axis group for a 2-axis T-Gantry Ethercat network wiring: Ethercat master softmotion -> Beckhoff EK1100 -> Servo drive #1 -> Servo drive #2 Ethercat Cycle time = 4ms Max Jitter = 140~150 What i have tried so far: - changed the sync offset from 20% to 30% - changed ethercat task priority from 1 to 0 Running tasks: - Ethercat tast: Prio = 0, Interval = 4ms - Main task: Prio = 1, Interval = 8ms - Visu task: Prio = 31, Interval = 100ms - Softmotion planning task: Prio = 15, Freewheeling - 3 other default tasks that were created by AC_Persist Motion fb's are called in the ethercat task... Does anyone have an idea how to fix this? Any help is greatly appreciated!

hi everyone, continuing the part about omron g5 axis and nx-ecc201 omron, but i have a problem with not being able to scan with "model with Z code suffix of omron china", it seems that the available softmotion file is not fully compatible mapping, often causing ethercat communication error DC distributed clock after every 10-12 hours of continuous running! omron driver: R88D-KN08H-ECT-Z
