Status control

The status of ten tabs of the DGM200P board is displayed here.

  • NO_RCLK (r) 1 = no receiving clock is detected on the fiber optic input port.

  • SLAVE (r) 1 = the card is configured as "slave." The jumper "master" is removed.

  • FEF (r) 1 = all data has been copied from the input buffer to the DPR.

  • /LFI (r) 0 = link fault indication, one of the following conditions applies:

    • receive frequency out of range

    • receive amplitude too small

    • no flow change in input difference signal for at least 60 cycles

    • receiver is blocked

  • MOD0 (r) 0 = fiber-optical transceiver block is available.

  • TXFAULT (r) 1 = transmitting laser diode is deactivated.

  • LOS (r) 1 = loss of signal, no light at receiver

  • INIT_LWL (rw) A rising edge starts the initialization of the fiber optic link. NOTE: The normal data exchange will be interrupted! Force to zero in normal operation.

  • EN_DGM (r) 1 = m-controller on the card has released transmission/receiving logical control.

  • EN_TR (rw) 1 = release of transmitter
PCI Info

In the PCI Info area of the dialog, you find the following information:

  • Slot Number Number of the PCI slot where the card is plugged in.

  • Bus Number PCI bus connected with this slot

  • Mem. Address Start address of the memory region (hex)

  • Memory Length Size of the memory region (hex), free / reserved
Diagnosis Info

In the diagnosis info area, you will find information helpful for service and support.

  • ms counter a running microseconds counter

  • IRQ mask Interrupt mask / interrupt status (for further information, refer to the card documentation of the manufacturer)

  • Port name Includes the station name. It is only valid after the connection to the data concentrator has been established.

  • Port number Includes the number of the port at the concentrator to which the station is connected via fiber optic cable. It is only valid after the connection to the data concentrator has been established.

  • Max. telegram length After the configuration has been attuned to the concentrator, you will find here the max. length of the telegrams sent by this port. The length is limited to 4096 (incl. overhead). If the microcontroller computes a greater max. length, no message will be send. The message length is only valid after the connection to the data concentrator has been established.

  • CPU load Time in microseconds between falling edge of the SYNC pulse and termination of all tasks.

  • Software version Contains software version as ASCII text

  • Hardware version Contains hardware version (four BCD characters)
Memory view

This view provides more detailed information about the message traffic for our support personnel.
