Why can't a property be of type REFERENCE TO? Plc goes to stop if I try that.

permissions, since a security related change it is not allowed to save files outside of the Plclogic directory. Use /var/opt/codesys/Plclogic/

Post by joanm on Programmatically change the IP addresses of the Modbus TCP slave devices ^{CODESYS Forge talk (Post)}
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

Post by albzen on EtherCat Slaves diagnosis ^{CODESYS Forge talk (Post)}
Hello everybody, I'm working on a RunTime Plc (Codesys 3.5.16/18.20) connected to an EtherCat bus with many devices. The bus has some communication fault but I don't know how understand which is the device or the cable that has the trouble. To understand the cause of the problem I would like to read the WKC (Working counter) of the devices (0x0300...0x030C), how is explained in EtherCat documents, but it seems that the read of the counter is disabled. Attached there is an extract of the Ethercat document. Can anyone give me some advice about how and with function can I read it. Thank you in advance!

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
I have a version of codesys 3.5.16 on my local machine and a vm. The local machine has loads of codesys versions and libraries installed etc. I can open the FPosCR_Example_Project_SP16_patch1 project on my vm without any errors. On the local machine I get the error C0077: unknown type IoDrvEthercatLib.ETC_CO_SdoWrite. I can, on the local machine, declare a var of type IoDrvEthercatLib.ETC_CO_SdoWrite and include it in the code without adding an extra error. The problem only seems to affect the library. This is seems more an issue with my codesys set up rather than something with festo. I would like to know the possible causes. I understand most of the library manager features but it's not clear how to find the cause. Thanks
