Technical Importance: Disaster Recovery and OEM Protection
The 1763-MM1 is an essential accessory for machine builders (OEMs) and maintenance departments alike. It allows for the «Load on Power-Up» or «Load on Error» features within the MicroLogix 1100. If the controller detects a memory corruption, it can automatically reload the master program from the 1763-MM1, restoring production in seconds without the need for a technician and a laptop. Furthermore, the 1763-MM1 is used to simplify field updates: an OEM can mail a programmed 1763-MM1 to a customer, who simply plugs it in to update the entire machine’s logic. It provides an extra layer of security beyond the standard 1763-BA battery, making it indispensable for critical infrastructure where program loss is not an option.
Installation Advice: Module Orientation and Software Settings
When installing the 1763-MM1, the PLC must be powered down. Remove the protective side cover of the MicroLogix 1100 and firmly seat the module into the slot. Once installed and powered up, you must configure the «Memory Module» properties within RSLogix 500. Here, you can decide whether the PLC should always load from the module or only if the internal memory is invalid. We recommend using the «Compare» function after a download to verify that the code on the 1763-MM1 perfectly matches the internal CPU memory. This ensures that in the event of an automatic load, the machine behaves exactly as intended.
Maintenance and Lifecycle Management
The 1763-MM1 is a solid-state flash device with no moving parts, making it extremely durable. However, it should be kept in its protective slot to prevent dust from contaminating the gold-plated pins. If the «Fault» LED on the controller is flashing after a memory load attempt, check for physical damage to the 1763-MM1 pins. Sourcing your 1763-MM1 from Atlantechdrives ensures you get a genuine Allen-Bradley accessory that provides the data integrity and read/write cycle endurance required for industrial environments.
FAQs
Q: Does the 1763-MM1 store the IP address?
A: Yes, if configured in the software, the Ethernet settings and IP address are stored along with the logic file.
Q: Can I remove the 1763-MM1 while the PLC is running?
A: No. Always power down the controller before removing or inserting any memory module to prevent electrical damage.
