Re: Maximum distance allowed between safety controllers for SMMC (Safe-Master-2-Master-Communication
Hello ... ,
SMMC for ctrlX SAFETY is based on Standard-Ethernet. Typically 100Mbit/s Fast-Ethernet is used.
Consequently the standard is 100m max. distance between devices, if you use a single cable.
If you put a switch right in the middle that can be extended to maximum twice the distance and respectively more with more switches.
But … you can extend the distance up to 4500m in one step using media converters like the Phoenix Contact FL MC 2000E LC device that we provide as HAWA (ask our technical sales and support people for HAWA accessories!). The media converter has been selected for Sercos but works of course for the lower requirements of Standard Fast-Ethernet.
