I. REGULATORY CONTROL FUNCTION BLOCKS
set AUTO to let system decide according to function block’s real
connection.
♦ Kind of CAS Mark
An APCS mark is designated in [Kind of CAS Mark] of the Function Block
Detail Definition window. The behavior of the Instrument Faceplate
depending on the designation of [CAS Mark] and [Kind of CAS Mark] is
shown in the table below.
*1: Indicates the default.
Table: Behavior of the Instrument Faceplate by the Designation of [CAS Mark] and [Kind
of CAS]
♦ CMP Mark
This mark indicates that the block mode of the function block displayed on
the instrument faceplate is RCAS (remote cascade) or ROUT (remote
output).
♦ Scale Low/High Limit, Scale Reverse Display
The scale high limit (SH) and scale low limit (SL) of engineering unit data,
up to 7 digits including a sign and a decimal point, can be set. Default
values are “100.00” for SH and “0.0” for SL. Up to nine digits can be
specified for a batch set block. When the reverse scale display is
specified, the low limit is displayed at the top of the scale and the high limit
at the bottom of the scale.
♦ MV Reverse Display
In the standard display of a function block faceplate, the high limit displays
at the top and the low limit displays at the bottom. To designate the MV
reverse-display may upside-down the standard display. In this case, the
pointer of manipulated output value (MV) behaves oppositely in
accordance to the digital value of parameters. This designation only
changes the display of function block’s faceplate and does not relate to
the actual output value. If a valve’s Open/Close is opposite, it is
convenient to use this function when aligning the valves function block
faceplate with other blocks in the same group.
