11-6 ArmorStart® to ArmorPoint® Connectivity
Shown below is the array size that will also need to be changed to
match the Armor_Start_System.Max_Devices value.
Figure 11.6 System Array Size
Armor_Start_System.Max_Parameters defaults to 262, because the
maximum number of parameters in any existing ArmorStart product
is 262 or less. This amount can be easily be changed, and doing so
will also proportionally change the size of the System Array structure
and the Logix memory that holds it. Shown below is the array size
that will also need to be changed to be 1 greater than the
Armor_Start_System.Max_Parameters value. This is because the
parameters are stored by parameter number, and since there is no
parameter 0, that storage location is unused.
Figure 11.7 Array Size Parameter
Armor_Start_System.Num_Devices defaults to zero and is defined as
the total number of ArmorStart products connected to the control
system that need to be configured. It is important that this value be
set before the configuration routine is executed.
It is to the users best advantage to trim the structures down to the
minimum values that match their system because this will save a
considerable amount of Logix processor memory. However, some
room should be left in the structures to handle any future additions of
ArmorStart devices to the system.
