Description

The Allen-Bradley 1746-BLM is a dedicated specialty module engineered for the SLC 500 platform to facilitate precise control in plastic blow molding applications. As an intelligent co-processor, it handles complex parison profile management and servo-loop execution autonomously, effectively offloading these compute-intensive tasks from the main SLC 500 processor. This module is compatible with various molding architectures, including continuous extrusion, reciprocating screw, and accumulator head systems.

Features

Four independent axes of PID control, supporting flexible configuration for parison and accumulator push-out operations.
High-speed loop update rate of 100 microseconds for real-time responsiveness.
256-point profile resolution with advanced interpolation for consistent wall thickness and part quality.
Dynamic profile adjustment capability, allowing for weight modification without compromising the integrity of the established parison shape.
Integrated 14-bit resolution for both analog inputs and outputs, ensuring high-precision signal processing.

Installation Guidelines

Ensure the SLC 500 chassis power is disconnected before installing or removing the 1746-BLM module.
Handle the module using proper ESD precautions to prevent damage to sensitive internal circuitry.
Secure the module firmly into the designated SLC 500 I/O slot to ensure reliable backplane communication.
Route signal wiring away from high-voltage cables or high-EMI sources to maintain signal integrity for the 14-bit analog channels.
Verify that the backplane power supply capacity is sufficient to support the 110 mA (5V) and 85 mA (24V) requirements of this module.

FAQ

What type of blow molding machines does the 1746-BLM support?

This module is versatile and supports continuous extrusion, reciprocating screw, and accumulator head blow molding machinery.

Does the module require the SLC 500 processor to handle the PID loops?

No, the 1746-BLM functions as an intelligent co-processor. It executes the PID control and profile management independently, which reduces the scan time impact on the main SLC 500 processor.
