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.
