Reference Brief Description
Advance6 None Use Case 6 — Scan 160 channels using 7703 module (see
NOTE):
• Type K thermocouple (TC) temperature measurements.
• Reference junction – Simulated.
• Measurement speed (rate) – 0.01 plc.
• Filter – Disabled (no filtering).
• Buffer – Store 160 reading strings. Buffer elements include
reading and channel #.
• Triggering – Bus control source.
• Data retrieval – Continuously store data into buffer. Retrieve
data for every 32 readings.
NOTE: When using a module that has a built-in cold junction,
use the Internal reference junction. Keep in mind that the
buffer and data retrieval will have to be modified to
accommodate the number of scanned channels. Modules
that have cold junction include:
7700 and 7706 modules – 20 available TC channels
7708 module – 40 available TC channels
Advance7 None Use Case 7 — Ten 40-channel scans using 7702 module:
• Channel 1 uses an external reference junction.
• Measurement speed (rate) – 1 plc.
• Filter – Repeat, 25 readings.
• Channels 2 through 40 are connected to type K thermocouples.
• Measurement speed (rate) – 1 plc.
• Filter – Disabled (no filtering).
• Open thermocouple detection – Enabled.
• Buffer – Store 400 reading strings. Buffer elements include
reading, real time clock, and channel #.
• Triggering – Bus control source.
• Data retrieval – SRQ when buffer
