Configured for removable program and user-data storage in AC500 PLC systems, the ABB 1SAP180100R0001 (MC502 SD Memory Card) provides Flash EPROM storage for controller applications, user data, and project transfer. ABB identifies MC502 as an AC500 SD Memory Card. Current ABB product data lists 2,000,000 kB memory capacity, while older ABB documentation and accessory listings identify the same order code as 512 MB.

Technical Identifier Matrix

ABB's current product page identifies 1SAP180100R0001 as MC502, while ABB catalog material identifies the same order code as an SD Memory Card for AC500.

Hardware Specifications

The physical dimensions above reproduce ABB's published product-dimension fields: 100 mm width, 170 mm height, and 5 mm depth. These database dimensions should not be confused with the actual semiconductor SD media dimensions.

ABB's older AC500 documentation lists MC502, order code 1SAP180100R0001, as a 512 MB SD Memory Card and specifies a 0.020 kg unit weight in that catalog revision.

PLC Memory and Firmware Compatibility

MC502 uses Flash EPROM for both user-data and user-program storage. Within an AC500 configuration, the memory card provides removable non-volatile storage rather than acting as a PLC CPU or I/O module. ABB classifies the device as a PLC memory card under the AC500 accessory structure.

The supplied project-transfer procedure uses ABB Automation Builder to rebuild the application, export the boot project and firmware, and copy the generated file structure to the memory-card root directory. The procedure should be matched to the controller firmware and Automation Builder version used by the target AC500 CPU.

Package Contents & Ordering Information

Field Installation Guidelines

• Verify that the target controller supports MC502 before inserting the memory card.
• Confirm the controller firmware and Automation Builder project version before transferring application files.
• Use the appropriate ABB memory-card adapter where the specific AC500 CPU requires an adapter.
• Do not remove the card during an active read/write operation.
• Keep the card protected from electrostatic discharge during handling.
• Install and remove the card with the controller in the state specified by the applicable CPU hardware manual.
• For project deployment, rebuild the application before exporting the boot project and firmware.
• Copy the generated boot-project structure to the root directory of the memory card rather than introducing an additional parent folder.
• Verify that the card is fully seated before initiating a memory-card operation.

Frequently Asked Questions

• Q: What is the memory technology used by MC502?
  A: ABB specifies Flash EPROM for both user-data and user-program memory functions. The card provides non-volatile storage for AC500 controller data.
• Q: What is the rated capacity of 1SAP180100R0001?
  A: ABB documentation is inconsistent across revisions. Current ABB data lists 2,000,000 kB, while earlier AC500 documentation identifies MC502 as 512 MB.
• Q: What is the operating temperature range?
  A: The specified operating ambient temperature is 0 to +60 deg C. The storage range is -40 to +70 deg C.
• Q: What is the maximum operating altitude?
  A: ABB specifies a maximum permissible operating altitude of 2000 m for the MC502 memory card.
• Q: Does MC502 provide non-volatile program storage?
  A: Yes. ABB identifies the user-program memory type as Flash EPROM, providing non-volatile storage for controller application data.
• Q: Is MC502 an AC500 I/O module?
  A: No. MC502 is classified as a PLC memory card and AC500SD  accessory. It does not provide discrete or analog field I/O channels.
• Q: What protection rating is specified for MC502?
  A: ABB product data specifies IP20. The card should therefore be installed within equipment providing the environmental protection required by the application.
• Q: What software is associated with MC502?
  A: ABB lists PS501-PROG Control Builder Plus for the AC500 platform. Current engineering workflows may use Automation Builder according to the controller generation and project configuration
