Features

This 4-axis position-control module has these features:

• Open-loop or closed-loop control

• Independent and coordinated axis control

• Position- and time-based control

• Accumulator push-out control

• Zero-scale/full-scale (offset & span) calibration for position inputs

• PID with anti-windup, bumpless parameter changes, setpoint weighting, and 

limited high-frequency derivative gain.

• Profile interpolation (linear or cubic spline) between setpoints

• Converging/diverging tooling (direct/reverse acting control)

• Three hold values per axis: manual position, purge, or die gap

• Independent profile scale and offset adjustments 

• Automatic parison weight adjustment

• Setpoint marking

Shared memory

From the ladder programmer’s perspective, communication with the module is via 

five data files located in shared memory on the module:

Config(G) File

contains information regarding the operational mode and feature 

settings of the module. You specify the contents of this file with 

the ladder logic programming utility (RSLogix500). Entries in the 

file are static and read-only from the module’s perspective (e.g. 

time vs. position based operation). This file is automatically 

downloaded to the module when you switch the SLC processor to Run mode.
