OPERATOR PAGE & PARAMETERS

The Operator page contains the parameters that are used most frequently and the commands that are required for day-to-day 

operation. This page is not locked for editing by Master Lock. The Figure 3.2 below illustrates how to access Operator Page 

(Page 0).

RESET COMMAND

This feature clears the current Min/Max values of all Channels and 
starts afresh monitoring the channels for new highest and lowest 
values.

For resetting, set the reset command to ‘Yes’.

View Only

(Default : NA)

MINIMUM PV

The minimum PV attained by the selected channel.

View Only

(Default : NA)

MAXIMUM PV

The maximum PV attained by the selected channel.

No

Yes

(Default : No)

1 to Actual no. of

Channels to Scan

(Default : 1)

CHANNEL NUMBER

Select the channel No. whose Min/Max PV is to be viewed. 

This Parameter reappears cyclically after viewing Max/Min Values 
for each selected channel number.

1 Sec. to 99 Sec.

(Default : 3 Sec.)

SCAN RATE

Applicable for Auto Scan Mode only. This parameter value sets the 
time interval for which each channel is displayed. In other words, 
the  rate  at  which  the  channels  are  sequentially  updated  for 
indication.

The Operator Page parameters are listed in Table 3.4 below.
