9-3-4 Error Descriptions
Event name Safety Process Data Communications Not Established,
Incorrect FSoE Slave Address Error
Event code 35230000 hex
Meaning Safety process data communications was not established with the Safety CPU Unit because of an incorrect FSoE
slave address.
Source Depends on where the Sysmac Stu-
dio is connected and the system con-
figuration.
Source details NX Unit Detection timing When safety pro-
cess data com-
munications are
established
Error attributes Level Minor fault Recovery For request to
establish commu-
nications from
