G-10 KE2700 Instrument Driver Examples Model 2701 User’s Manual
Name Manual Reference Brief Description
Simple6 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 only.
• Triggering – Bus control source.
NOTE: When using a module that has a built-in cold junction,
use the Internal reference junction. Keep in mind that
the buffer 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
Simple7 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).
• Buffer – Store 400 reading strings. Buffer elements include
reading only.
• Triggering – Bus control source.
