Out of Service (O/S)

The block is not being evaluated. The output is
maintained at last value or, in the case of output class
function blocks, the output may be maintained at an
assigned fail-safe value, last vlaue or configured fail-
safe value.

Manual 1 (Man)

The block output is not being calculated, although it
may be litimed. It is directly set by the operator through
an interface device.

Automatic (Auto)

A local setpoint value is used by the normal block
algorithm in determining the primary output value. The
local setpoint value may be written to by an operator
through an interface device.

Remote Cascade

The block setpoint is being set by a Control Application

(RCas)running on an interface device through the
remote cascade parameter RCAS_IN. Based on this
setpoint, the normal block algorithm determines the
primary output valvue.
