8.3 How to Confirm Flow Configuration
After performing flow configuration for the device by using "Flow Configuration Wizard" and
"Download to Device", execute the following procedures to confirm the configuration.
NOTE
Regarding start up procedure of digitalYEWFLO and DYFMVTool, refer to Appendix B-1.
IMPORTANT
Use function block scheduling and connection tool for DYFMVTool. After using these setting tool,
finish the program before starting FlowNavigator.
The procedures differ depending on whether AR Block is used standalone or connected with
other devices.
Case1: AR Block is standalone. Refer to section 8.3.1
Case2: AR Block is connected with other devices. Refer to section 8.3.2
Figure 8.19 shows the parameters for confirming the flow configuration.
Regarding Flow Calculation of digitalYEWFLO and DYFMVTool, refer to section 6.1.3 and
the document "Model DY Vortex Flowmeter, Model DYA Vortex Flow Converter, Fieldbus
Communication Type" (IM 01F06F00-01E).
