Post by rajesh008 on i can't declear the address in GVL - codesys SP19 Patch5 ^{CODESYS Forge talk (Post)}
The “_AB AT %IW0:word; ” if i called the value then im getting this error. like below "the declartion of the variable with an address assignment cannot be used in a PRG or GVL with the attribute 'subsequent'" This is happening when the GVL is selected in Redundancy Configuration. if i un-select the address declaration is working fine

Post by kporter on Codesys EtherCAT Driver (CmpEt1000MPD) can't set MAC address ^{CODESYS Forge talk (Post)}
EtherCAT is a point-to-point protocol so it doesn't need a unique MAC address. It would be very useful to set the MAC address to 020000000000, the standard address for this kind of application. (The important bit is the 02 at the start of the address, which means locally-administered MAC.) The stock Windows driver can do this for my i210 card. But the CODESYS CmpEt1000MPD driver cannot. The image shows the setting with the Windows driver. If I set all my customers' cards to this address, then I don't need to deal with this when deploying my application. A simple PowerShell script can be used to set the MAC address once when the NIC is installed and the driver is changed.
