[. . . ] Indicates the internal connection parameters used by the master to maintain the connection information. Metric column PhyAddress column The end result of the routing and connection data is that any device or master can communicate with any other device or Master, regardless of the physical connection of the device. Note that Masters may only be "connected" to each other via Ethernet/TCP/IP. 1 on page 91), NetLinx Studio is running on a PC connected to System #7 as device number 32002. The routing capabilities of the NetLinx Master allow NetLinx Studio to download IR codes to the NXC-IRS4 (S=7 D=24), a master firmware upgrade to NetLinx Master #1, and new touch panel pages to the touch panel on Master #1. All of this is possible simply by having NetLinx Studio connected to a NetLinx Master with M2M firmware. Design considerations and constraints The routing metric limit of 15 usable hops imposes some constraints on the topology of the interconnected NetLinx masters. While the limit of 15 hops may seem very limiting, this is not really the case if you carefully architect the topology. 3 Single dimensional view of the maximum number of interconnected NetLinx masters This shows a maximum of 15 masters connected to each other, such that any master is routeable to any other master. 3 into two dimensions and takes advantage of the fact that each NetLinx master supports multiple connections to masters. FIG. 4 Two-dimensional view of the maximum number of interconnected NetLinx masters NetLinx Programming Language Reference Guide 93 Master-To-Master (M2M) FIG. 4 shows that a maximum of 64 systems can be interconnected using a two-dimensional interconnection topology. Using a three-dimensional topology, even more systems can be interconnected (FIG. 5 Three-dimensional view of the maximum number of interconnected NetLinx masters FIG. 5 shows that a maximum of 512 systems can be interconnected using a three-dimensional interconnection topology. 4 that a single NetLinx master may have up to eight connections to remote masters (all 6 sides of the "box" plus two diagonal connections). The maximum number of TCP/IP connections supported by a single master is 200 simultaneous TCP/IP connections. Another possible connection topology is to establish communication hubs that optimize the traffic with adjacent masters but still allows connections to other masters, as shown in FIG. 6 Clustered master topology When determining the interconnection topology of many NetLinx Masters, special consideration should be made to the Masters that communicate large amounts of information with each other. Thus, if you have 2 systems that share devices, control, or information, they should be side-by-side in the topology, not at opposite ends of the connection Matrix where each message is forced to pass through several NetLinx Masters. 94 NetLinx Programming Language Reference Guide Master-To-Master (M2M) Control/NetLinx Language Support The features of control to M2M include channel control (PUSH/RELEASE/ON/OFF/TO), level control, send commands, and send strings. Channel controls allow one NetLinx master to PUSH/RELEASE a channel on a device of another system via the DO_PUSH/DO_RELEASE functions. Additionally, ON, OFF, TO, and feedback statements can control channels on devices of remote systems. If a channel has a characteristic modifier associated with it, that modifier still applies to the channel, regardless of whether the channel is manipulated locally or remotely. For example, if a group of channels and variables is mutually exclusive, an ON to one of the channels will turn off all other channels and variables in the group prior to turning on the desired channel. [. . . ] Input change: A signal sent by the input function of a channel that alerts NetLinx to scan mainline for a reference to that signal. Integer: In NetLinx, the range of whole numbers from Ø to 65, 535, inclusive. Integer array: An array where each location can hold a value ranging from Ø to 65, 535. Note that an integer array will take up twice as much NetLinx memory than would a character array of the same storage capacity. [. . . ]
