Error Processing
At the occurrence of an error:
•
the corresponding error code is transferred to device
variables
*_ErrCode1 and *_ErrCode2
•
the corresponding error code is stored inside the SSI Unit
•
the Global Error device variable *_GlblErr is turned ON
•
the ERC LED indicator or ERH LED indicator is turned ON
The following errors codes can be reported in device variables
*_ErrCode1 and *_ErrCode2
*_ErrCode 1
*_ErrCode2
Description
0300
Offset (see
configuration
device
variable table
above)
The setting for the Device
Variable is out of range. Use the
*_ErrCode2 offset to identify the
Device Variable.
0310
Offset (see
configuration
device
variable table
above)
The setting for the Device
Variable has an invalid BCD-
code (The range of a valid BCD-
code for a digit is 0-9. If one or
more digits are within range A –
F, an invalid BCD-code is
specified). Use the *_ErrCode2
offset to identify the Device
Variable.
Countermeasure: Configuration errors can be cleared by correcting
the faulty settings in device variables and transferring the new
configuration data to the Unit. To transfer the configuration data:
•
Turn the power of the NJ system ON, or
•
Restart the Unit
*_ErrCode 1
*_ErrCode2
Description
0490
CH
No.
00
Parity error in SSI channel CH No.
Countermeasure: Check if the unit is configured to check for the
correct type of parity (even or odd). Check the SSI-encoder.
*_ErrCode 1
*_ErrCode2
Description
0490
CH
No.
01
SSI-encoder channel CH No. not
ready
Countermeasure: This error appears in case the data line is low right
before the communication with the encoder connected to channel CH
No. is started. Check the cabling between the unit and the SSI-
encoder. Check the SSI-encoder.
*_ErrCode 1
*_ErrCode2
Description
0490
CH
No.
02
SSI-encoder channel CH No. time-
out
Countermeasure: This error appears in case the data line is and
stays low after the mono-flop time has expired on channel CH No.
Check if the unit is configured for the correct encoder settings. Check
the cabling between the unit and the SSI-encoder. Check the SSI-
encoder.
*_ErrCode 1
*_ErrCode2
Description
0002
Time-out in
ms (hex)
A cyclic refresh time-out error was
generated caused by a PLC system
error or you have chosen to disable
the Cyclic Refresh of the SSI Unit
in the NJ-series CPU Unit. This
error will be cleared as soon as
Cyclic Refresh or IORF will take
place.
000E
0000
An error has occurred on the I/O
Bus causing the SSI Unit to be in
an undefined state.
Countermeasure: Turn ON the power supply again or restart the
system. If the error persists then replace the NJ CPU.
