Common features of I/O channel blocks
There are certain attributes and parameters that are common to all I/O channel blocks.
The following section identifies these common features.
Defining Mode and Attribute settings
The MODE parameter determines the operating mode for the channel block. These
modes apply to both Digital Output and Analog Output channel blocks.
Operators are only permitted to change MODE if:
 MODEPERM is set to Permit, and
 REDTAG is set to Off
Note: Mode Permissive = Indicates if the operator can change the mode of a function
block.
Red Tag - Allows the user to set the FB as being "out-of-service"; this indicates that the
function block or the associated control strategy needs repair, or is being repaired.
The following modes apply to the MODE parameter.
