MXC Quick Access keys are used to view transmitter

parameters while the MXC is on-line and communicating with a

transmitter (refer to Section 2). Eight Quick Access keys are

used with the Model 344: TRANS. VAR'S., TREND, ZOOM,

and STATUS, are available with the controller ON or OFF.

CHANGE SP, CHANGE VALVE, A/M and TUNE are only

available when the controller is ON. Press a key to access live

transmitter data.

NOTE

in the on-line mode.

1. Establish communication with a transmitter, see Section 3.2,

and go to the On-Line Menu (adjacent).

2. Press a Quick Access key to view the desired transmitter

parameter(s) at the On-Line Menu. The following

paragraphs will describe how to view these parameters.

TRANS. VAR'S. - displays updated on-line transmitter

parameters. These parameters include the measured

variable (MV), the current output (I), the process variable

(PV) and their respective units or the Process (P), Set Point

(S) and Valve (V) controller variables.. Exit this screen by

again pressing the TRANS. VAR'S. key or pressing END.

TREND - displays the adjacent screen to select the variable

to be trended.

If the sample time entered is greater than 300 seconds, a

Warning message will appear that shows the range of
