2-3-1 Backup Function
Function Overview The backup function records the parameter data of all Slice I/O Units con-
nected to the Communications Unit. The parameter data recorded in the
Communications Unit can be restored to the Slice I/O Units later with the
automatic restore function when a Slice I/O Unit has been replaced.
Backup Procedure when
using a DeviceNet
Communications Unit
1,2,3... 1. Verify that the power is ON, DIP switch pin 1 (REGS) is ON, and all of the
Slice I/O Units are participating in I/O communications.
