Introduction

1746 Process Control is orderable as:1746-BTM, 1746-BLM

Blow Molding Module. This module features four independent axes of PID control plus one discrete I/O pair per channel for channel synchronization. The 1746-BLM module provides 256 points of resolution for each parison channel with interpolation, and has loop update times of 100 microseconds. Configurations include accumulator push-out control and three parison axis, and two accumulator push-outs and two parison axis.The Blow Molding Module is designed to work in a variety of applications, including accumulator machines, continuous extrusion machines, and reciprocating screw machines. The module performs its servo control task independently from the processor, but receives its configuration and run-time information from the processor.

Barrel Temperature Module. This module provides four zones of Auto tuned 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.
