10. Series 8 I/O Troubleshooting
10.1 Initial checks
This section offers checks that you can make to help isolate a problem. The checks are
arranged but not in a particular order.
Checking Control Builder error code reference
An indication of a problem may be in the form of an error dialog that includes an error
message and possibly an error code in Control Builder.
The syntax for a typical Control Builder error message is as follows:
Connection to device is not open EPKS_E_CL_NOCONN(6L.101.3326)
In this syntax, the error code is the last four digits in the message or 3326.
Refer to the Control Builder Error Codes Reference Guide for applicable error code
information.
Checking front panel display and LEDs
Check the Series 8 module character display and Series 8 IOTA light emitting diodes
(LEDs) indications.
