  • Page 101 APPENDIX A.7 Trace The J.NET module collects trace data for each network (N1, N2). Trace is started in the error stop mode (error occurrence, trace stop) when the CPU is reset or power is recovered. Trace data is recorded in transmission or reception units of each service. The trace data structure is shown below.
