Publication 1746-UM010B-EN-P - April 2001

P-2 Preface

SLC Processor

The 1746-BTM module is compatible with any SLC processor that

supports M0/M1 files, such as the SLC 5/05, SLC 5/04, SLC 5/03, and

SLC 5/02 controllers.

Vocabulary

In this manual, we refer to:

• the barrel temperature control module as the “1746-BTM

module,” the “BTM module,” or as “the module”

• the programmable controller as the “SLC processor”, or “the

processor”

• a thermocouple as a “TC”

• a time-proportioned output as “TPO”

• the tuning-assisted processes as “TAP”

• proportional-integral-derivative as “PID”

• cold-junction compensation as “CJC”
