Features

System limitations:

  • At source time stamped events online change service is not available.

  • Internal PLC variables can not be timed stamped using at source time stamping solution.

  • No selection of transition edges on time stamped events in a BMX ERT 1604 T module (events are time stamped on rising and falling edges).

  • In a Modicon M340 local drop, the maximum number of BMX ERT 1604 T modules depends on the local drop CPU type, refer to Compatibility and Limitations topic for more details.

  • In a Quantum application, only 25 BMX ERT 1604 T modules are supported per application.

  • In an M580 application, the number of BMX ERT 1604 T modules per application is not limited.

    NOTE: For M580 CPU with OS version ≤ 2.40, the number of BMX ERT 1604 T modules per application is limited to 25.

  • A Modicon X80 Ethernet RIO drop supports up to 36 expert channels. A BMX ERT 1604 T module is counted as 4 expert channels.

  • Maximum of 9 x 140 ERT 854 10 modules in a S908 drop.

  • Maximum of 8 x 140 ERT 854 20 modules in a S908 drop.

  • Maximum of 2500 discrete I/Os per Quantum PLC.

  • Maximum of 144 discrete inputs per Modicon M340 PLC (local drop).

  • The CCOTF function is not supported by BMX ERT 1604 T modules.

Compatibility:

  • A Hot Standby system is compatible with applicative time stamping. For more details on Hot Standby system, refer to the Modicon Quantum Hot Standby System User Manual.

  • A Quantum Safety PLC is compatible with applicative time stamping. For more details, refer to the Modicon Quantum, Quantum Safety PLC, Safety Reference Manual.
