Logix Database Filtering

Descriptions of the parameters are as follows:

l Impose Array Element Count Limit: When checked, an array element count limit is imposed. Tags in

the controller can be declared with very large array dimensions. By default, arrays are completely

expanded during the tag generation process, which becomes time consuming for large arrays. By

imposing a limit, only a specified number of elements from each dimension are generated. Limits only

takes effect when the array dimension size is exceeds the limit. The default setting is unchecked.

l Element Count Limit: This parameter is used to specify the element count limit. The default setting is

2000.

1761-NET-ENI Setup

1761-NET-ENI provides a means of communicating with ControlLogix, CompactLogix, FlexLogix, MicroLogix, SLC

500, and PLC-5 Series PLCs on Ethernet with the Allen-Bradley ControlLogix Ethernet Driver.

Requirements

MicroLogix, SLC 500, or PLC-5 series PLC supporting Full Duplex DF1 utilizing the CH0 RS232 channel.

1761-NET-ENI Device Series A, B, C, or D.

ControlLogix, CompactLogix or FlexLogix PLC utilizing the CH0 RS232 channel.

1761-NET-ENI Device Series B and newer.

Note 1: For communications parameters, database settings, and project/protocol options, ENI ControlLogix,

CompactLogix, and FlexLogix users should refer to the "Logix Setup" book in the Table of Contents.

Note 2: To turn on the CompactLogix Routing option (located in the utility's ENI IP Addr tab), use the ENI /

ENIW utility supplied by Allen-Bradley. This was tested on an ENI module with Firmware revision 2.31.

Important: The ENI module has a limited number of TCP connections. As such, users should avoid applications

that communicate with the module (such as RSLinx/RSWho) so that connections are available for the driver.

ENI Device ID

The device ID specifies the IP address of the 1761-NET-ENI. Device IDs are specified as the following:
