I am using a WAGO PFC200 PLC as an etherCAT master and a Keyence IV3-G120 with DL-EC1A attached as an etherCAT slave. I am using CODESYS V3.5 SP21 Patch 3. I was able to set up mailbox communication and can see values changing accordingly, but I want to know how I can map these values and reference them in my program. I am able to map the process data objects in the 'EtherCAT I/O Mapping' tab, but there is no where to map the mailbox values in the 'CoE Online' tab. Is there a way I can reference one of these values in my code?

Post by pernockham on Gateway in China - "Gateway not connected"

I think I understand my problem. They are most probably related to configuration of the network. When I use DHCP for the unit to my router it all works. However when using static IP I have not managed to reach functioning state. Trying to replicate the situation on my desk. Having a static IP on the "debian host" and a connection to my computer which then routes traffic on to internet. I have entered settings for gateway and netmask. I can ping from my "debian plc host" to internet and also do "curl google.com" so traffic seems to find its way through and back, still "Automation server" will not find the gateway. Any hints how a manual configuration should be done? Is it possibly a "firewall" issue of my "normal router"? Thanks for any help! Per

CODESYS is placing many of the classic CAA libraries into a Service Phase starting March 1, 2026, meaning: They are no longer recommended for new development. They will remain available only for existing use via bug-fix support until around March 1, 2030. Modern, better alternatives already exist or are being pushed as replacements. Examples of libraries entering Service Phase include: CAA Net Base Services, CAA Async Manager, CAA List and Tree, CAA BehaviourModel, etc. There’s also a shift in other internal areas — older networking (UDP/TCP), behaviour and buffer libraries, historic templates, and real-time-clock helpers are all being phased out in favor of newer tech. geometry dash lite
