SECNDS

Use

This resident point counts real time seconds and can be used as a timer. The computer adds one (1) to the SECNDS variable for every one second of real time that passes.

  • The initial value of the SECNDS point is set by a PPCL command.
  • The SECNDS point can be set to a maximum value of 9,999.
  • SECNDS points do not roll over. The present value will stay at 9,999 until it is written to a value less than 9,999.

Example

890  IF (SFAN.NE.PRFON) THEN SECNDS = 0

Notes

For APOGEE automation stations, each program has a unique SECNDS point. This point can also be viewed in the interface using the program name, system delimiter (:)SECNDS format.

SECNDS are also local variables and can only be seen locally in the device, not over BACnet. If necessary, they can be linked to BACnet AV, BV, or MSV to be read over the network.
