The ACE3600 remote terminal unit (RTU) combines the local processing of a PLC with the superior communications of a remote terminal unit for an all-in-one high-performance unit. It allows seamless integration with multiple PLCs, RTUs and Intelligent Electronic Devices (IED). A powerful processor combined with versatile input/output modules allows this RTU to be used for the most demanding SCADA applications, including those in:
Oil and Gas
Water and Wastewater
ACE3600 RTUs can be expanded with multiple, simultaneously operating communication ports in a range of industry protocols. The communication capability is specifically designed to support secure communications over diverse networks.
Remote control and monitoring applications
Water/Wastewater: Improve distribution system or collection system operation, optimize treatment plants and realize chemical and energy savings.
Electric power distribution: Implement Distribution Automation systems by controlling load break switchgear, reclosers and other IEDs (intelligent electronic devices).at substations, pad or pole top locations.
Oil & gas pipelines: Monitor and control flow, pressure, cathodic voltage; perform emergency shutdowns, monitor remote exploration and storage sites.
Early warning/siren control: Perform routine tests and remotely activate sirens for public annunciation of emergency conditions.
Communication network monitoring and control: Perform remote monitoring of critical equipment such as power systems, environmental control systems, tower lights, etc.
Fire station alerting: Quickly dispatch fire equipment and resources with remote control of lights, sirens, voice public address systems, doors, etc.
Versatile communications options
Supports up to 5 ports, ACE3600 can simultaneously communicate over RS-232, RS-485, radio and IP, while using the same/different protocols.

SECURITY against hacking
ROLE-BASED ACCESS CONTROL
Assign specific roles and permissions to perform certain operations based on those roles. i.e. security admin could define roles and assign permission to each role.
Data-at-Rest (DAR) protection ensures all data stored on devices or applications is encrypted with FIPS 140-2 validated AES 256 bit encryption significantly reducing the threat of lifting confidential data from compromised devices. Ensure secure data in transit with end to end encryption with AES 256 bit encryption.
Permit or deny data transmission into your system or device based on rules and established criteria. All IP messages must pass through a firewall which examines each one and blocks those not meeting security criteria.
Monitor any and all activity including suspicious activity or deviations from set security policy. Any attempt of unauthorized access to a secre ACE3600 RTU will be blocked and logged. The security log is encrypted and saved in FLASH memory to prevent malicious alteration and can be retrieved for forensic purposes after the event.
Verify access to an RTU is legitimate from both other RTUs or system users with authentication.
UNUSED PORT DEACTIVATION
The ACE3600 RTU enables unused ports to be disabled, reducing its vulnerability to unauthorized access.
APPLICATION CONTROL SOFTWARE
Block unauthorized applications from your components by allowing only pre-approved programs to run. The ACE3600 RTU have application control mechanisms tested by McAfee Solidifier.
Add additional layer of defense to limit the risk of replay attacks such as disgruntled employee with legitimate access. Timestamps are added to the command messages. The subsequent “action” must be received within a designated time and contain elements that match otherwise the action will be rejected.
INTRUSION DETECTION SYSTEM
Automatically look for malicious activity or violates security policies. The ACE3600 will only allow legitimate traffic to enter and block malicious activity. Unauthorized activity is logged and can be reported to a designated control center.
