Document Type and Number:
WIPO Patent Application WO/1989/002100
Kind Code:
A1
Abstract:
A signal trace control system for tracing and storing particular signals in a programmable machine controller (PMC). Designated trace signals are supervised by a supervising means (21) which collects them in one place (R510), and trace signals are written in a trace buffer (2) by a write control means (22) in response to trace control signals from the supervising means (21). Since signals to be traced are collected in one place, there is realized a signal trace control system having a short tracing time.
