SECTION 7
Error Processing
This section covers functions, procedures, and operational differences that are relevant when errors occur in your system.
The table of Section 7-1 provides easy reference to indicator functions, error causes, and appropriate corrective measures.
Section 7-2 shows how to monitor errors through SR words and the Programming Console. The procedures used to locate
transmission errors are outlined in Section 7-3, while Section 7-4 provides two tables that illustrate operational differ-
ences when errors occur in CONTINUE and STOP modes. Finally, Section 7-5 gives three possible methods to achieve
system recovery for errors in STOP mode.
