Chapter 7 - Trouble-shooting Communications
Ports (NOT Pseudo Slave Ports) to communicate with their Master nodes.
If the top level node does NOT have a Slave port, then ACLINK (or the
Workbench 'Build' command) will incorporate ANY existing node routing
table into the load. As long as the high slave address values are correct
throughout the network, peer-to-peer communication may work with an
incorrect node routing table, since the Master Module actually uses local
communications (although it will report a -23 error on its STATUS_2
signal if there is no node routing table present.) Attempts at global
communications, however, will almost certainly fail.
If the top level node DOES have an active, connected Slave Port, it is
permissible to download via the Pseudo Slave Port, however, global
communications will not be available until a time synchronization with
the master (which includes a Node Routing Table transmission) has
occurred. To avoid this delay, it is best to follow the rule of downloading
via the Slave Port.
[ ] 3. FOR BSAP NETWORKS ONLY: IF YOU HAVE A PSEUDO
MASTER PLUGGED INTO A LOWER LEVEL NODE, MAKE SURE
YOU DOWNLOAD TO THE CORRECT NODE:
For DOS-based Tools (UOI, AIC, Toolkit, Taskspy):
If you are working with a section of the network, and download via a
Slave port, then you should have used the Communications Setup Menu
to identify the NAME of the node to which you are connected. Otherwise,
the system will "believe" that the current node is a Top-Level Node as
defined in NETTOP and messages will almost certainly not be directed to
the proper nodes.
For Open BSI 2.3 (or earlier) Users:
If you are working with a section of the network, and download via a
Slave port, make sure the "Local" option is selected, and the correct
node is selected in the Communication Line Parameters dialog box of
the Open BSI Setup Tool. Otherwise, the system will "believe" that the
current node is a Top-Level Node as defined in NETTOP and messages
will almost certainly not be directed to the proper nodes.
For Open BSI 3.0 (or newer) Users:
Establish
Downloader from within LocalView. This will ensure you are downloading
to the correct node.
