Figure 17 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.
Adding Devices to the Configuration Structure
Once the three major System level parameters are entered, it is up to the
user to enter in, each of the ArmorStart devices configuration information.
These parameters are defined by the slot in the Logix chassis where the
EtherNetIP or ControlNet communication card resides. The next parameter
is the EtherNetIP IP or ControlNet node address of the 1738 communication
adapter containing the ArmorStart. Lastly, the slot number on the
ArmorPoint subnet where the ArmorStart is connected also needs to be
entered. An optional parameter is a string that can be entered with a
description of the function of the ArmorStart device. Each device will be
configured by entering its data into a different block of the
Armor_Start_System.Device[] array.
The Following shows the configuration for a communication card in the
Logix chassis 2, AENT IP address 192.168.1.10 and Point I/O slot 3. The
logic determines whether the network is EtherNetIP or ControlNet
depending on whether the ENET_IP_Addr field is blank or the
CNET_Address is zero. One of these two fields must be filled out for the
logic to work correctly. The Armor_Descriptor field is optional and is used
to more easily identify the ArmorStart as to its function in the system.
