High-Level Security Overview

Product Link's end-to-end system is designed with multi-layer security controls and safeguards, to protect against unauthorized access and disclosure. High-level security safeguards include, but are not limited to:

  • Cryptographic security controls to protect against unauthorized Product Link device software changes
  • Encrypted and authenticated remote connection
  • Only outbound remote connection, initiated by the Product Link device is allowed. Device does not participate in or respond to general Internet traffic
  • Caterpillar IT infrastructure secured utilizing generally accepted information security principles and practices
  • Secure web application connection with user login authentication and role-based access controls

Industrial protocols

When the configuration file is loaded into the PLE601, the gateway functionality is enabled. The gateway functionality allows the customer to read equipment data using various industrial protocols over RS-232, RS-485, or TCP/IP. The standard configuration provided by Caterpillar iscustomized to the engine. The configuration also includes a standard protocol mapping that is consistent across all engines.

  • Modbus Master and Slave
  • Allen Bradley Ethernet I/P
  • Siemens S7

The gateway functionality can also be used to bring data to the PLE601 from other devices and added to the Customer Defined Parameters.
