    Properties Properties The FM 450-1 is a fast counter module to be used in the S7-400 automation system. There are two counters on the module which can work in the following counting ranges as required: • 0 to 4 294 967 295 (0 to 2 - 1) •...
  • Page 10 1.2 Properties Load value You can determine an initial value (load value) for each counter on the FM 450-1 The counter is set at the initial value if a software or hardware-related signal to the module comes up. Hardware interrupts When comparison values are reached, for overflow, underflow and/or for zero crossing of a counter, the FM 450-1 can trigger a Hardware interrupt.

  • Page 19: Gate Functions

    Many applications require that the counting process should be started or stopped at a specifically defined point in time, depending on other events. In the case of the FM 450-1 starting and stopping the counting process like this take place via a gate function. If the gate is opened, count pulses can reach a counter and the counting process is started.

  • Page 95: Data Error

    Data error When do data errors occur? If new parameters are transferred to the module, the FM 450-1 checks these parameters. If errors occur during this check, the module reports these data errors. Wrong parameters are not accepted by the module.

  • Page 96: Operator Error

    How are data errors acknowledged? Correct the values for the parameters to comply with the specifications. Transfer the corrected set of parameters to the FM 450-1 again. This again checks the parameters and deletes the data error in DB 1.
  • Page 97 Mode cannot be started using the SW gate. Mode cannot be aborted. Permitted only if OD is active How are operator errors acknowledged? Acknowledge the error with parameter OT_ERR_A in DB 1. Counter module FM 450-1 Equipment Manual, 03/2022, A5E03648739-AC...
