Rack Interface Module
The RIM has a set of status indicators which are visible through the rack fascia. The
primary functions and positions are shown above.
Fault indicators will be illuminated during initialisation and during reset. During
normal operation the two green status indicators will be illuminated.
The upper group of four indicators are:
Function Colour Notes
System Run Green System passed all power on tests and ‘healthy’
System Fault Red System watchdog or reset has occurred
Comms active Green Power on confidence tests passed and 'healthy'
Swap Green Reserved for future development
Procedure in the event of faults
(1) Is the rack address set correctly ?
Check that two racks do not share the same address.
(2) Failure to communicate with the modules in the extension rack.
Are any of the I/O modules registered as 'Actual Module' on the Hardware
Definition screen ?
Are analogue input or output modules listed on the screen but no digital I/O ?
Is the inter-rack cable sound ?
Are the modules fitted in the extension rack of the correct type (i.e. any module
except communication or combined analogue input or output) ?
(3) Is the communications link terminated correctly?
Ensure that LK 8 and 9 are fitted to the LAST rack only.
