5 PARAMETER SETTINGS
1: The operation mode of a remote I/O station under the error status can be set
differently from the parameters of the remote master station (CPU module).
When an error (fuse blowout or I/O verification error) occurs on the remote
master station (CPU module) and remote I/O station, the data link and output
of the remote I/O station are determined based on the combination of the
parameter settings of remote I/O stations and remote master station (CPU
module).
The table below shows the status of the data link and output of the remote
I/O station based on the combination of parameter settings.
