3.2 I/O AND LOOP FUNCTION BLOCKS
This section provides a detailed description of each input/output and loop function block. Blocks are listed
alphabetically.
3.2.1 A/M - A/M Transfer
One
A/M
function block can be used per loop and it is
normally used on the output of controller blocks to
enable auto/manual operation of the loop. It is separate
from the controller block allowing the option of
inserting other function blocks (e.g. override,
feedforward) between the controller and the A/M
Transfer. If function block PB3SW has been used the
A/M block is not available.
A
UTO allows the signal from the controller (input A) to
become the output of the A/M Transfer unless EMER
MAN or STANDBY is active. Auto ONLY forces the
operator pushbutton to be locked in the
A
UTO position,
but EMEG MAN and STANDBY will function
normally.
M
ANual allows the operator to adjust the manual value
unless STANDBY is active. The manual value tracks the
block output when in AUTO or STANDBY. The manual
value can be adjusted when in MAN, provided the
displayed variable is the process or the valve (e.g.
TC2053.P or TC2053.V). When a loop is switched to
MANual the display will automatically show the valve
(e.g. TC2053.V). The range pointer (input Range) lets
the A/M function block know the range of the auto input
signal and enables the A/M block to properly process
pulser changes from the operator faceplate. The range pointer also defines the range of the manual function as -
10% to 110%. This can be useful to prevent inadvertent changes from an operator workstation that might set the
manual value well beyond the local operator’s changeable range. In most cases, the Range input (range pointer)
will connect to the controller function block. An unconfigured range pointer will default the range to 0.00 - 100.00.
