When the timer is in operation the communications cycle time is fixed at the specified value independent of the number of events that occur Refer to 4 77 Data Link Characteristics for the formula needed to calculate the communica tions cycle time when the data link is set for automatic generation Maximum Node Address This parameter sets the maximum node address that a node can have and still be a part of the network Nodes with node addresses greater than the maximum node address will not be polled and therefore will not participate in network communications This eliminates unnecessary polling of units with node addresses above the maximum and thus reduces the time required for communications Set the maximum node address above the highest node address set on the SYSMAC LINK Units currently connected unless you specifically want to exclude one or more nodes from system operation Number of Polled Nodes This parameter determines how many nodes will be polled by the polling node during a polling cycle Setting a high number of Units increases the communi cations cycle time but reduces the time required to recognize that nodes have been removed from or added to the network Maximum Number of Frames This parameter determines how many event transmissions can take place during a token cycle when data links are operating With the default value of 10 frames up to 4 event transmissions can be issued Event transmissions includ
