During the save, a pop-up window is displayed, allowing the user to specify which
configuration has priority.
Selecting “Configuration from EEPROM has priority” means:
The PCD3.T76x will only start up if the configuration from the Master matches the
configuration stored in EEPROM. This function allows a desired I/O configuration to
be pre-defined and saved to the PCD3.T76x. The Master will only start up if it has the
same I/O configuration as the PCD3.T76x.
Selecting “Configuration from Master has priority” means:
The PCD3.T76x will always start up with the configuration received from the Master.
This function is normally used during commissioning, where no Master is yet
connected to the PCD3.T76x. Saving the configuration (set up in the web server) to
EEPROM allows more rapid commissioning.
The configuration stored in this way is taken as the default configuration when the
unit is connected to the Master.
Clear EEPROM
This function is not available in Monitoring mode. This function clears the whole
EEPROM, the PCD3.T76x configuration, the “lock” list and the EEPROM priority.
Clear all “locks”
This function is not available in Monitoring mode. This function clears all “locks” in the
PCD3.T76x RAM; the “lock” in EEPROM is retained.
Start/Stop monitoring
This button enables the user to switch to Monitoring or Configuration mode. Start/
Stop monitoring is only available where the configuration in the device-specific web-
pages for the PCD3.T76x matches that in the PCD3.T76x itself.
Synchronizing the configuration
This tool is based on a complicated mechanism that monitors whether the
configuration in the PCD3.T76x matches that in the device-specific web pages for
the PCD3.T76x. If the two configurations are not the same, some functions, such
as “Start Monitoring” and “Save to EEPROM”, will not be available. In this case, the
buttons for these functions will be blocked, as shown on the next page.
