SmartSlice I/O System Errors

Communication Unit
TS Colour
Not Lit --- Power is not being supplied to the Unit.
Flashing Green Joining SmartSlice I/O Units to network.
(1 Hz)
There is a possible break in the connection
between individual slices, or one of the Smart-
Slice sockets has not been connected properly
to its left neighboring connector.
The TS LED Indicator on all correctly connected
slices are flashing, whereas the TS LED Indica-
tors on the non-correct Units are Not Lit (OFF).
The End Unit is not (properly) attached. Smart-
Slice Communication does not start up.
The TS LED Indicator on all SmartSlice I/O Units
slices are flashing.
Red SmartSlice bus communication error occurred.
When the registration table function is enabled,
the actual configuration does not match the reg-
istered configuration.
The total number of I/O points in the SmartSlice
I/O Systems exceeds the maximum.

If power supply to the Unit and the SmartSlice I/O Units is correct, the Unit will
start initialization at power up. During the Initialization process the RUN LED
indicator will remain OFF. Once the initialization has been completed cor-
rectly, the RUN LED indicator will be ON.
The table below indicates the states which can occur during startup and oper-
ation of the Unit.
Probable cause
If power supply to the Unit is correct and the Unit has initialized correctly,
problems in the SmartSlice I/O system can be determined using the TS LED
indicators on the PROFIBUS Communication Unit as well on the individual
SmartSlice I/O Units. When lit or flashing, the TS LED indicator can be either
Green or Red.
The tables below lists the TS LED indicator options.
Probable cause
Correction
--
Replace the Unit.
Restart the Unit. If the problem persists, replace
the Unit.
Correction
Refer to section 4-2-1 Power Supply Errors.
Wait until the SmartSlice I/O Units have been
added to the network.
Check the connection between slices at the point
where the first Unit is located with its TS LED
Indicator OFF.
Ensure that all slices are connected correctly to
each other.
Check the End Unit connection and ensure that it
is correctly connected to the SmartSlice system.
Check whether the SmartSlice I/O System's
base block is connected properly.
Correct the configuration and turn the power ON
again.
Correct the Unit configuration and number of I/O
points and turn the power ON again.
Wait until the restore operation is completed.
Wait until the backup operation is completed.
