8.3.1 Case1: Arithmetic Function Block is Standalone
Following is the procedures for confirming flow configuration in case AR Block is standalone.
Step 1 Set function block scheduling information
Set the function block scheduling information to activate digitalYEWFLO AR Block.
Regarding function block scheduling, refer to Appendix B-2.
Step 2 Open Online Parameter in Device DTM
Start Device DTM to display the Online Parameter screen.
([Device] → [Parameter] → [Online Parameter])
IMPORTANT
Turn on the alarm output of AR Block at TB: ALARM_PERFORM.
Default setting for the alarm output of AR Block is off.
([Online Parameter] → [Transducer Block] → [Alerts])
Step 3 Set input conditions in AR Block
Set value to following input parameters (Refer to Figure 8.19 and Table 8.10):
“Input.Value”, “Input1.Value” and “Input2.Value”
([Online Parameter] → [Arithmetic] → [Dynamic Variables])
