7.3 Set-Up
After the MSR300 System has been assembled, it must be programmed with information
about the system modules configuration. This data is stored in non-volatile memory and
compared with the configuration detected each time the system is switched on. Any
difference between the freshly detected configuration and the programmed configuration
is interpreted as an error condition. This prevents unintentional modifications in the
system configuration.
Configuration detection and saving:
Unintended modifications to MSR300 Systems are prevented by design. The system
configuration is automatically checked when it is first started up, and this information is
stored in non-volatile memory (EEPROM) in the Base Module. Whenever the system is
started up (or restarted) thereafter, the current system configuration is checked against
the stored configuration. If a discrepancy is detected, a fault response is immediately
generated, with appropriate diagnostic indication and output.
The Base Module is set up in auto-detection mode as default. If it is powered up the first
time it will automatically read in the configuration of the connected modules.
Follow the procedure below for changes or modifications of the configuration.
Procedure for auto detecting and storing a new system
configuration:
1. Disconnect Expansion Modules from the Base Module.
2. Insert the bus terminator plug into the left bus connector.
3. Power up the Base Module:
a) The "Status" LED blinks to indicate that the Base Module
is in configuration detection mode. LED indication:
b) The previous configuration is erased.
4. Disconnect the power after at least one blink of the LED.
5. Remove the bus terminator plug from the Base Module, and
then connect the required Expansion Modules to the Base
Module.
6. Insert the bus terminator plug into the free bus connector of
the last Expansion Module.
7. Power up the system. After powering up, the current
configuration is detected and stored by the Base Module in
internal EEPROM.
8. The MSR300 System then automatically steps into normal
operating mode.
