AS-P Server Communication Ports

An AS-P server has the following communication ports:

  • 2 Ethernet 10/100 megabit ports

  • 2 RS-485 ports

  • 2 LonWorks (TP/FT and RS-485) ports (not available on the AS-P-NL and AS-P-NLS model s )

  • 1 USB host port

  • 1 USB device port

  • 1 backplane I/O bus port

  1. The AS-P server models AS-P-NL and AS-P-NLS do not support LonWorks.

The Ethernet communication is performed over a 10/100BaseTX, 10 or 100 Mbit/s, twisted pair network. The AS-P servers have two Ethernet ports with RJ45 connectors.

The two Ethernet ports can be configured in three different modes: switching enabled, second port disabled, or dual IP networks. One port should be connected to the site network. When switching between the two ports is enabled, the other port can be used to connect computers running WorkStation or WebStation, Modbus TCP units, or BACnet/IP devices such as MP controllers, but not another EcoStruxure BMS server. To limit access to the system, you can disconnect the second port. When the two ports are configured in dual IP mode, y ou can connect a separate network of IP devices to the second port. The automation server has the option to act as a DHCP server on this network. You can lock the DHCP network and only allow current DHCP clients to communicate with the automation server.

The USB host port (facing down) can be used for connecting devices such as the Advanced Display (AD) and Wireless Adapter - Advanced. For more information, see Connecting AD v3 to an Automation Server and a 24 VDC Power Supply .For more information, see Wireless Adapter - Advanced .

The USB device port on the front is intended for program download from a PC by means of Device Administrator. It is connected to a PC or a downstream port of a hub.
