Scanning
t^okfkd
The 7702 module is designed to handle DC peak voltages up to 300V
generated by external and potentially unlimited energy type sources.
When the 7702 module is used in conjunction with the 7751/7753 mod-
ule, it can be used safely up to the full output voltage capability of the
7751/7753 V-source (500V DC peak). This DOES NOT imply the 7702
module can be used with EXTERNAL SOURCES (i.e., non-7751/7753
derived) above 300V DC peak.

Standard scanning can only be performed using a 7702 switching module. To
scan through 7751/7752/7753 channels, use memory patterns (
Section 2 ).
• Scanning fundamentals — Explains channel assignments (slot/channel program-
ming format), the difference between sequential and non-sequential scans, and the
basic scan process. Block diagrams (known as trigger models) are provided to help
explain the STEP and SCAN operations.
• Scan configuration (7702 only) — Provides the step-by-step procedures to con-
figure a simple scan or an advanced scan. Covers other scan options, including
delay, monitor, auto configuration, saving setups, and auto scan.
• Scan operation (7702 only) — Provides the step-by step procedures to perform a
basic scan, a manual/external trigger scan, and a monitor scan.
• Remote programming — scanning — Provides the commands used for scan
operation and includes a simple scanning programming example. Also summarizes
various aspects of remote scan operation.
• Scanning examples — Provides a couple of typical scan operation examples (front
panel and remote programming).
