S
Max Masters: Defines the highest MS/TP Master MAC
address on this MS/TP network. For example, if there are
3 master nodes on an MS/TP network, and their MAC
addresses are 1, 8, and 16, then Max Masters would be set
to 16 (since this is the highest MS/TP MAC address on
the network). This property optimizes MS/TP network
communications by preventing token passes and “poll for
master” requests to non--existent Master nodes (i.e., in
the above example, MAC address 16 would know to pass
the token back to MAC address 1 instead of counting up
to MAC address 127). Each MS/TP master node on the
network must have their Max Masters set to this same
value. The default is 127.
S
MaxInfo Frames: This property defines the maximum
number of responses that will be sent when our controller
gets the token. A valid number is any positive integer.
The default is 10 and should be ideal for the majority of
applications. In cases where the controller is the target of
many requests, this number could be increased as high as
100 or 200.
NOTE: MS/TP networks can be comprised of both Master
and Slave nodes. Valid MAC addresses for Master nodes are
0 -- 127 and valid addresses for Slave nodes are 0 -- 254.
NOTE: See RTU--MP 3rd Party Integration Guide for
Protocol Maps.
