Table 13-19 Error Codes For Communication Errors - Hitachi S10VE User Manual

13. Troubleshooting
(b) Return code errors
When a J.NET module detects an error on the communications line, the module sets the ALM of the S
register and the error flag of the NET status to ON. The module then writes an error code in the S table
to record the error information.
