Field Manager
Multi-Applications Field Process Manager
The FM-AA01 is the device that manages all the field processes of the different applications and the interactions among the applications.
The most important capability is the peer-to-peer communications of the FM-AA01 present in the system which allows a totally “server independent” integrated security system.
Field Managers are intelligent “multi-application” units with an autonomous database that the XAtl@s software updates in on-line mode. It can execute all field processes related to different applications (access control, intrusion detection, time & attendance, …) autonomously. The failures of a Terminal, a Field Device, the System Server, or of a communication line, does not affect the Field Manager functionalities.
Field Managers communicate with each other in peer-to-peer mode via Ethernet with TCP/IP protocol. The same interface and protocol are used to communicate with the system server running XAtl@s.
The interface of the Field Managers with the external environment and users is managed by the Field Devices connected via Field Bus or Terminals connected via Ethernet or other serial interfaces. The FD-BUS is a proprietary bus that uses the same UTP cable for data and power distribution.
If you are configuring a multisite plant, you can assign Field Managers to each site in order to manage controls. In this way, the supervision center will send homogeneous site-specific data to the group of Field Processors responsible for controlling a given site.
Functional characteristics
The main characteristics of FM-AA01 are:
• CPU GEODE SCx200 266MHz processor (Pentium II class)
• 128Mbyte RAM
• 64Mbyte CompactFlash memory
• LAN 10/100BaseT communications port (Fast Ethernet)
• Manages 2 separate FD-BUS backbones
• Optically isolated RS485 on FD-BUS-B for interfacing with third-party terminals
• 32bit PCMCIA slot (Cardbus) for expansion with high speed devices (WIFI, ADSL)
• Host USB port for expansion with low-speed devices (modem, WEB cam, Bluetooth, biometric sensors)
• RS232 serial port for diagnosis and configuration (BIOS)
• Autonomous clock & calendar
• Tamper (anti-opening) protection
• Linux operating system
• Programming language:JavaTM
• Encrypted communications (SSL) on Ethernet LAN
Protection
The equipment is protected against the following events:
• polarity reversal on cables (RJ45) connecting to the FD-BUS
• voltage surge in the power supply
Modes of Operation
The FM-AA01 module is part of the Orangelink system and can perform Field Manager functions.It can control either OrangeLink Field Devices and third party’s devices on both the FD-BUS A and FD-BUS B backbones (from 300 baud to 115 Kbaud). The two backbones can communicate at two different speeds at the same time. The normal speed for OrangeLink Field Devices is 115 Kbaud. The module is fully configurable remotely over the LAN.
Applications are activated as soon as the FM-AA01 has received the configuration database from its supervisor.
Once it has received the database, the FM-AA01 is able to operate autonomously even without the LAN.
Visual indicators
The FM-AA01 module can give indications to the user by means of:
• Red + green LED for BIOS status
• Red + green LED for Ethernet status
• Red + green LED for application (link) status
• Red + green LED for FD-BUS A status
• Red + green LED for FD-BUS B status
