The safety control system consists of a Safety CPU Unit and a CIP Safety on EtherNet/IP device.
The Safety CPU Unit performs safety controls with another Safety CPU Unit and a CIP Safety on
EtherNet/IP device through
"safety process data communications". (Dashed arrows in the above fig-
ure.)
The Safety CPU Unit can perform standard I/O control with a standard CPU Unit through "standard
process data communications". (Dashed arrows in the above figure.)
