Hi everyone I have a client who wants to datalog to csv files on a Codesys PLC and have this data uploaded to the cloud. However these machines have no access to internet as they are in the middle of the nowhere. Here is their idea: once a day, they want to export that csv file to an Android device that is on the same LAN and have that file be automatically transfered to the cloud once the Android device regains internet access back at the office. We will be using the Android device as a middle man....
This now makes complete sense and validates the behavior I was observing. Thank you for your help. I have issued a bug report to the manufacturer and have found a work around for now as per your suggestion. Thank you

Here is a snip of the Input and Output assembly mapping with Bit 5 and 6 that I was mentioning.
Hi @i-campbell Still no improved results after more troubleshooting. The VFD still gives an IO message timeout fault if I am holding a constant speed command. I can also see in the Codesys Mapping that the Link for EthernetIP module: https://download.lenze.com/TD/COM__ESV__SMV%20EtherNet-IP%20module__v2-0B__EN.pdf I've followed the commissioning procedure with no luck. I've attached the Wireshark results. One thing I am noticing is that the feedback from the VFD doesn't match exactly what Codesys...
Thanks @i-campbell Your suggestion solved one of the issues: I no longer get a connection failure every 10 seconds or so. However I still have this issue: If am varying the speed command, the VFD will function normally until the speed is held at a constant value after which a timeout fault will occur. The VFD documentation labels this as an "IO Message Timeout Error". This seems to indicate that the speed command and enable command is only transmitting 'on change' however everything seems to be set...
Hello everyone I am having a hard time diagnosing an intermittent Ethernet Connection Failure. I am using some Lenze SMV Frequency Drives and communicating to them over EthernetIP from a Control Win soft PLC and compiler V3.5.17.20. I am noticing two different behaviors: If am varying the speed command, the VFD will function normally until the speed is held at a constant value after which a timeout fault will occur. This seems to indicate that the speed command is only transmitting 'on change' however...
Hello I am working on an application and it seems that the alarm manager doesn't always pick up alarms that are active for a single program cycle. For example: a timer expiring. The process will run until the timer expires, however the alarm signal of the expired timer is only active for one cycle and the process is stopped. This seems to be too quick for the alarm manager to pick it up and display the error or warning in the alarm table. My solution in the past has been to introduce a TOF on the...
