ACE3600
The ACE3600 is a new powerful Remote Terminal Unit (RTU) in Motorola’s family of Supervisory Control And Data Acquisition (SCADA) products. ACE3600 provides an advanced data collection and processing unit with the intelligence required to operate in sophisticated SCADA systems. Advanced communication and networking capabilities include data transfer via two-way radio, trunked radio, digital radio, data radio, cellular modems, IP networks, line modem and more.
Local Intelligence
ACE3600 is a microprocessor-based RTU with large memory capacity that can make control decisions on-site, based on status conditions and values from local and remote sources. Local intelligence permits control decisions without the need for real-time messages from other supervisory centers; ACE3600 can operate in sophisticated control systems.
Programmable
ACE3600 uses an advanced symbolic ladder logic application language to develop the data base conditions, values, and RTU profile that must exist for each control action, message transmission, etc. to occur. Routines written in ‘C’ may be executed as a whole or part of the total application. Powerful applications may easily be defined using industry accepted ladder logic and ‘C’. The task is made easier by using the SCADA application development software and a PC-style computer.
Protocols
ACE3600 uses the OSI-based MDLC communication protocol for all data signaling. Third party MODBUS, DNP 3.0 DF1 (Allen Bradley) and IEC 60870-5 protocols are also supported. MDLC was specifically developed for radio use but is completely applicable to Ethernet, wireline, and other media. It permits large volumes of data to be quickly transferred between units using packet transmission techniques. The MDLC protocol enables adding the ACE3600 easily to existing MOSCAD systems where system expansion is required.
Communications
ACE3600 permits communication to occur RTU-to-central and RTU-to-RTU (peer-to-peer). Communication may occur between individual units or may be broadcast to several units simultaneously. Store-&-forward may be employed to pass messages RTU-to-RTU throughout the system. Direct communication, where possible, or repeated messaging over one or multiple communication media, may be intermixed within the system.
Upload/Download
ACE3600, via the MDLC data transfer capability, uploads the data collected and calculated by the application program to a central site. It also receives downloaded changes to the application program and/or to the parameters that control how the application operates. The process being supervised does not need to be static; operational variables and limits, and the process definition itself, can be easily changed and transmitted to the RTU from anywhere in the system’s network. A unique feature of ACE3600, also enables remote firmware safe download from anywhere in the system’s network. This allows remote firmware upgrades. The above features minimize site visits by maintenance personnel after the unit’s initial installation.
Communication Ports
Connectors on the various CPU modules permit the connection for local application programming, or connection to other onsite devices to supervise their operation, and to the communication media device. Multiple connectors, multiple communication types, and variable data speeds allow practically all external data devices to be connected to the CPU module.
Chassis and Enclosures
ACE3600 can be provided on a metal chassis or in a painted steel NEMA-4X (IP56) rated outdoor enclosure that can hold the RTU frame, modules, battery and up to two radios (depending on enclosure size). An optional tamper switch can be ordered with the enclosure.
19" Rackmount
ACE3600 may be ordered with frame and mounting accessories that permit direct mounting onto standard 19” equipment racks. The frame contains space for power supply, CPU module and up to eight I/O modules. Optionally, a 19” metal chassis can be ordered for installation of backup battery, accessories and up to two radios.
What others are saying
"Marc Brauer, Todd Brauer and the rest of the ITS team come highly recommended by Wake County as they have shown us that they are highly skilled in the setup, maintenance, and enhancement of the Motorola SCADA and the Wonderware InTouch product lines."
