Never Interrupts Your Process
High reliability is essential for the systems that control your critical processes. The dual redundant capability of the field control node (FCN) autonomous controller ensures that these processes continue without interruption even when a damaged module is replaced.
Automatic switchover without interrupting your process
If the control-side CPU fails, the stand-by CPU automatically detects this and takes over control. To maintain consistency, all process data is synchronized on the stand-by and control-side CPUs.
When a hot-swappable CPU module is replaced, the module automatically functions as the stand-by CPU by synchronizing both application and database without interrupting the process. No PC tools are required to perform this synchronization.
Easy Engineering for Redundant Applications
No special engineering work or dedicated CPU modules are required for redundant applications. The stand-by and control CPUs also use the same spare parts, allowing users to keep fewer parts in stock.
Minimize TCO by Minimizing Replacements
Power failure during disc access is a major cause of file corruption in the CPU module. Without having to replace the entire CPU module, it is possible to recover a damaged file system by replacing just the FCN system card.
