LCD Display

Five-digit LCD Display (1)

Shows Output value(OUT) of AI block, Address,

and Error Codes(AL XXX). Shows "-----" when

the communication has not been established,

for example immediately after power on, or

when AI block is not scheduled.

Unit Display (2)

Unit of OUT value displayed on the Five-digit

LCD.

Dot-matrix Display (3)

Shows name of the AI block whose OUT value

is displayed on the five-digit display(AI1, AI2,

AI3, AI4) and status of the OUT signal(Good,

Bad, Uncertain). Shows 'Stop' when the

communication has not been established, for

example immediately after power on, or when

AI block is not scheduled. Shows 'FAIL'. when a

hardware error is detected,

Signal type diplay (4)

Shows the type of the signal which is assigened

for AI block. (Sensor1, Sensor2, Terminal

Temperature, Average, Differential). For Sensor

back-up value, shows the sensor which is used

as current input value.

Bar-graph (5)

Always shows output value(OUT) of AI1.

Items are shown in cyclic way. An example of

display is shown below.

[ Overview ]

In the example below, parameters are set as shown in the box in the right.

As the transducer block and the resource block are currently in O/S mode, error codes

'AL021' and 'AL022' are shown in turn, and the status of OUT for both AI1 and AI2 appears

as 'Bad'. If the status of OUT is 'good', 'G.D' is shown in place. If it is 'uncertain', 'UnC' is

displayed.
