Description

• This program illustrates how to utilize the FLOW function to calculate instantaneous flow rate, based on a pulse input, and to manually log accumulated flow.

• The FLOW function, inserted into network #3, is configured to calculate the instantaneous flow rate and accumulated flow based on the number of pulses received on pulse input counter CNTR0, register 30009. It utilizes three normally open contacts to manually control its operation and is configured to maintain up to 35 periods of accumulated flow data.

• The Register Editor dialog has been pre-configured to display all pertinent registers used in this program.

• The controller type has been pre-selected as SCADAPack.

• The Register Assignment has been pre-configured with the SCADAPack 5601 I/O and CNTR Controller Counter Inputs modules.

• Refer to the "Ladder Logic Function Reference | Ladder Logic Function Reference | Ladder Logic Functions" section of the "TelePACE User and Reference Manual" for information on the FLOW function.
