METSO PDP403 logical unit module

Panel Bus Topologies • Up to 16 Panel Bus I/O modules can be controlled by a single XCL8010 Controller. • Panel Bus I/O modules must be addressed using the HEX switch. • Maximum distance between controller and Panel Bus I/O module: 40 m. • No bus termination • Polarity-insensitive The LONWORKS Bus is a 78-kilobit serial link that uses transformer isolation so that the bus wiring does not have a polarity. I.e. it is not important which of the two LONWORKS Bus terminals are connected to each wire of the twisted pair. The LONWORKS Bus does not need to be shielded on the controller module side. The LONWORKS Bus can be wired in daisy chain, star, loop or any combination thereof as long as the maximum wire length requirements are met. Configuration The recommended configuration is a daisy chain with two bus terminations. This layout allows for max. LONWORKS Bus lengths, and its simple structure presents the least number of possible problems, particularly when adding on to an existing bus. See also “LONWORKS Mechanisms”, Product Literature no.: EN0B-0270GE51.Via the C-Bus up to 30 C-Bus devices (e.g., controllers, etc.) can communicate with one another and a PC central. The C-Bus must be connected via the individual controllers (open ring). Note Star connection is not allowed because uncontrollable line reflections may occur. Instead of an Excel 800 Controllers, other C-Bus controllers (e.g., the Excel 500, Excel 100, Excel 50) can also be connected.

FTT Specification

 The FTT specification includes two components that must be met for proper system operation: • The distance from each transceiver to all other transceivers and to the termination must not exceed the max. node-to-node distance. • If multiple paths exist, the maximum total wire length is the total amount of wire used.Notes • The cable types listed above are as recommended by Echelon in their FTT-10A User Guide. • The cable recommended by Honeywell is the level IV, 22 AWG, solid core, non-shielded cable. • Belden part numbers are 9H2201504 (plenum) and 9D220150 (non-plenum)In the event that the limit on the total wire length is exceeded, the FTT physical layer repeaters (FTT 10A) can be added to interconnect segments. This increases the overall length by an amount equal to the original specification for that cable type and bus type for each repeater used. For example, adding repeaters for a doubly-terminated bus using JY (St) Y 2 x 2 x 0.8 cable increases the maximum length 900 m (3000 ft) for each repeater.
