DO Function Block
Range Initial Value
Data Type: Unsigned8
Defines action to be taken on remote control
device timeout.
Normal Return − actual mode changes to the next
lowest priority non-remote mode permitted but
0 returns to the target remote mode when the
remote computer completes the initialization
handshake.
No Return − Target mode changes to the next
lowest priority non-remote mode permitted. The
target remote mode is lost, so no return occurs.
Data Type: DS-66
Block set point and status after ramping, provided
Dynamic to a supervisory host for back calculation and to
allow action to be taken under limiting conditions or
mode change.
0=Undefined
Data Type: DS-73
This alert is generated by any change to the static
0=Undefined
data.

0
Data Type: DS-72
0 The block alarm is used for all configuration,
hardware, connection failure, or system problems
in the block. The cause of the alert is entered in
the subcode field. The first alert to become active
will set the active status in the status parameter.
0
As soon as the Unreported status is cleared by the
alert reporting procedure, and other block alert
may be reported without clearing the Active status,
0
if the subcode has changed.
0
0
Data Type: Float
0 The ramp rate for SP up in AUTO, CAS, and
RCAS modes. Measured in PV units/sec.
Data Type: Float
The ramp rate for SP down in AUTO, CAS, and
0
RCAS modes. Measured in PV units/sec.
