7.18.1 DSB block state after configuration and load
The Slave State (SLAVESTATE) parameter will be "COMMUNICATING." In the event of a communication
loss between the master and the slave device, the Connection Lost Counter (DSBCONNLOSTCOUNT) will
display the count.
Slave Status tab
The Slave Device (SLAVEDEVICE) and the Watchdog On (WATCHDOGON) LEDs will be green in normal
conditions. If a slave device has extended diagnostics, the Extended Diagnostics (EXTENDEDDIA) LED
appears red. Similarly, the corresponding LEDs will appear red based on the error condition.
You can view the extended diagnostics details from the Field Network Configuration tab. See "Viewing the
slave device's extended diagnosis" on page 101.
This tab is only applicable to the Generic DSBs and the DRIVEDSB. After the Generic DSBs or the DRIVEDSB is
loaded, if any of the defined alarms is active, the respective Condition Status (USERCONDITSTA) parameter will be
The Condition Status (USERCONDITSTA) parameter will be "On (1)" if any of the user-defined alarm
PDC tab / IOM Configuration tab
The following values in the PDC tab are updated from the DSB running on the PGM.
PDCSTATE - The state (PDCSTATE) of the PDCs that are configured but not connected to a PIOMB will
be "PDC Configured." The state of the PDCs that are connected to the PIOMB will be "PDC Connected."
However, the state of the PDCs that are not configured will be "PDC not Configured."
DATAMODULENBR - The Data Module Number (DATAMODULENBR) parameter will display the data
module number of the PDC provided by the "Profibus Network Configuration Tool".
PDCDATASIZE - The Data Size (PDCDATASIZE) parameter will display the data size of the data module
provided by the "Profibus Network Configuration Tool" appears in the Data Size column. This number
appears in the Monitoring view after the Generic DSBs is loaded.
