Function Blocks

3.2.54 ODA - Operator Display for Analog Indication & Alarming

ODA blocks are one of five operator displays that are used on a one

per loop basis to configure the local operator display functions and

network parameters. See the i|ware PC faceplate on the next page.

The block will display up to four process variables P1 to P4 in both

analog bargraph and digital form. Two alarms are associated with

each process variable. They can be configured as HI or LO alarms.

Each alarm function has associated block outputs that are high (1)

when the alarm is active. Output LE is high (1) when a loop event is

active. Output SE is high when a station error is active. LOOP #

parameters are used to index reads and writes to Modbus network

parameters. See Section 5 for network parameters.

The VIEW OD parameter, when set to YES, enables the operator

display to be viewed and accessed locally. In cases where it is desired

to view display or operation parameters only from a network

workstation, the parameter should be set to NO.

Range pointers (i.e. R1 to R4) for all four process inputs must be

configured to define the range of each variable input (i.e. P1 to P4). If

these parameters are not configured, the bargraphs will be scaled using

the engineering range of 0.00 to 100.00. This information also defines

the scaling of the loop information provided to a remote workstation

over the network (i.e. Modbus or Modbus/TCP Ethernet).

Each process variable can be displayed on the local faceplate using the

D button. When first stepping into a loop using the Loop button, the

loop tag will be displayed (e.g. AnDisp1). However, if there is a point

within the loop that has an unacknowledged alarm, that point will be

displayed alternating between the point tag and the alarm condition

(e.g. PI693/3B LO). Press the D button to scroll through the analog

points displaying the point tag (e.g. TI712) in the alphanumeric and

the value of the point in the digital display (e.g. 348.47). Press the

UNITS button to display the units of the point. Press the Loop tag to

return to displaying the loop tag.

Alarm Types

HI compares the process input with the limit setting and trips the

alarm status high (1) when the process is equal to or higher than the

limit setting. The alarm status will clear (0) when the process is less

than the limit setting minus the deadband.

LO compares the process input with the limit setting and trips the

alarm status high (1) when the process is equal to or less than the limit

setting. The alarm status will clear (0) when the process is greater than

the limit setting plus the deadband.

OR compares the process input with the range limits referenced by the

range pointer parameter. It will trip the alarm status high (1) when the

process is equal to or greater than the high limit, or equal to or less

than the low limit. The alarm status will clear (0) when the process is

less than the high limit minus the deadband or greater than the low

limit plus the deadband.
