Allen-Bradley 1747-DPS2: Dual Port SLC 500 Memory Cartridge

The Allen-Bradley 1747-DPS2 is a dual-port memory cartridge designed for use with the SLC 500 series programmable logic controllers (PLCs). It’s an essential tool for engineers and technicians looking to streamline program uploads, downloads, and backups without interrupting operations. From my experience, this module often becomes a go-to solution in environments where downtime needs to be minimized.

Key Features

• Dual Port Functionality: Allows simultaneous connection of two devices, such as a programming terminal and a network interface, reducing the need to disconnect equipment during troubleshooting or updates.
• Plug-and-Play Design: No additional configuration is required—just insert it into the SLC 500 processor slot, and you’re ready to go.
• Memory Expansion: Provides extra storage capacity for larger programs or data logs, which seems particularly useful for complex automation tasks.
• Reliable Data Integrity: Ensures that your program files remain secure during transfers, even in industrial settings with potential electrical noise.

Technical Specifications

Application Fields

The 1747-DPS2 finds its place in industries like manufacturing, food processing, and packaging, where SLC 500 systems are still widely used. For example, I’ve seen it deployed in bottling plants to allow operators to update control logic while keeping production running. In most cases, it’s also utilized in scenarios requiring frequent firmware updates or diagnostic access without halting machinery.

Advantages & Value

One thing I appreciate about the 1747-DPS2 is how it simplifies workflows by enabling parallel device connections. This not only saves time but also reduces the risk of errors during critical operations. Additionally, its compatibility with older SLC 500 systems ensures that upgrading isn’t necessary, which can lead to significant cost savings. You might notice that its robust build quality makes it well-suited for harsh industrial environments, further enhancing reliability.

Installation & Maintenance

Installing the 1747-DPS2 is straightforward—just slide it into the designated slot on the SLC 500 chassis. Ensure proper ventilation around the cabinet to prevent overheating, especially if other high-power modules are nearby. Routine maintenance typically involves checking the physical integrity of the cartridge and ensuring all connections are secure. Firmware updates may occasionally be required to maintain optimal performance.
