communication cards of National Instruments.

To conclude: When a tag is set, the schedule information and communication connection

information are automatically cleared.

2. Yokogawa Device Operation

When the schedule information of the function block is cleared, the operation of AI Block stops

and the LCD display values (for example, a pressure value in the case of EJA) cannot indicate

the current state.

Youneedtobecareful,becausethereisapossibilitythatthedisplayedPVvalue(usually,OUTof

AIBlock)isdifferentfromtheactualvalue.YoucanconrmtheactualvalueinDeviceViewer.

In this case, function block re-scheduling is necessary.
