Barrel Temperature Module
This module provides four zones of Autotuned PID heat/cool temperature control.
Each input functions as the process variable (PV) for a PID loop. The PID algorithm
and tuning-assisted process (TAP) algorithm are performed on the module for each of
the loops. The control variable (CV) output of each loop, either analog or time-
proportioned output (TPO), is sent from the module to the SLC data table. Your
application logic must access the CV value in the data table and send the analog or
TPO data to an output module to close the loop. The module is compatible with SLC
5/02 and higher processors.

Stepper Control Module
The 1746-HSTP1 is a single-axis stepper controller capable of providing up to 250
kHz pulse train output for micro-stepping applications. The module can interface
directly with a quadrature encoder to monitor position. Built-in loop back diagnostics
provide monitoring of pulse train commands. Programmable modes of operation
eliminate the need to set DIP switches.
