Description

• This program illustrates how to continually poll a generic HART transmitter that is connected to a 5904 HART Interface module.

• A UCTR (up counter) function is used to cycle through 4 HART messages that are continually being sent one after the other. Each Hart message is sent only when the previous message is responded to correctly or timed-out if the message fails. This prevents two HART messages from being sent accidentally at the same time.

• 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 CNFG 5904 HART Interface module.

• 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 HART, UCTR and CMPU functions.
