Monitoring and Operating the TREND Display
The TREND Display provides trend displays of PV, SV, MV, etc. in addition to the LOOP Display functions.
The TREND 1 Display can provide trend displays of PV1, SV1, and MV1; the TREND 2 Display can provide those of PV2, SV2,
andMV2;andtheTREND3DisplaycanshowthoseofanyfourdataselectedfromPV1,PV2,SV1,SV2,MV1,MV2,X1,X2,

Name Description
(1) Tag number
A tag number combining alphanumeric characters and symbols having a maximum of 12 digits
is displayed on a loop basis.
For TREND 3 Display, the tag number of the loop 1 is indicated.
(2) Display title The title of the display being shown is indicated.
(3) Digital display
PV, SV, and MV digital values are displayed.
For TREND 3 Display, data selections 1 to 4 are indicated.
(4) Trend display
The time span of the set trend display is divided into 60 partitions, and PV, SV and MV values
in the period of one time partition are displayed with the smallest and largest values of selected
data in the vertical line of one element. Trend display is clipped and displayed at 0% if a
relevant value is below 0% or at 100% if it exceeds 100%.
(5) Trend data pointers
PV, SV, and MV values and selected data are indicated with triangular pointers. The pointer
display moves up and down with a resolution of 0.5%.
(6)
Operation status
display
The controller operation status is displayed.

100% value of scale
The 0% value of scale (SCL) and the 100% value of scale (SCH) of PV and SV are displayed
on a loop basis in digital values of five significant digits (seven digits including a sign and
decimal point).
(9) Scale marks
A scale divided into a maximum of 10 divisions (10% segments) is displayed. Moreover,
horizontal lines corresponding to the scale marks are indicated in dotted lines.
