Configuring Local Slave Properties: The General page
Original instructions
About us
The General Page
Use the General page to configure the EtherNet/IP communication module to serve as an I/O adapter to a remote device.
The following steps describe a sample configuration of the local slave function. Your configuration may be different.
Configuring the Local Slave
To configure the local slave function, follow these steps:
Step
Action
1
In the Devices window, right click on the EtherNet/IP Local Slave icon, then select Properties in the popup menu.
The General page of the Local Slave properties window opens.
2
Enter settings (refer to the table below) for the following parameters to configure local slave functionality for the EtherNet/IP module.
Note: When using explicit messaging to read the EtherNet/IP module’s assembly object, be sure to allocate sufficient room for the response, because the size of the response will equal the sum of:
  the size of the assembly + Reply service (1 byte) + General Status (1 byte)
Local slave properties are described, below.

The next task is to configure slave inputs and outputs.
Local Slave Properties
The following property settings have been made in this example:.
Setting
Description
Device Designation section:
Active Configuration
  • A selected checkbox indicates the local slave service is enabled.
  • A de-selected checkbox indicates the local slave service is disabled and the current local slave service settings are saved.
In this example, this setting is selected.
Device Name
Assign the local slave a unique name, consisting of up to 32 characters, including numbers, letters, and the underscore character.
In this example, the auto-generated name DEVICE_A is accepted.
Number
The unique number—or identifier—assigned to the device.
In this example, select the number 001.
Comment
User-defined free text comment area. 80 characters maximum. In this example, leave blank.
Connection Health Bit Offset
Auto-generated integer (0...127) indicating the offset of the connection’s health bit in the status byte array of the input area.
Note: This setting is auto-generated only when the local slave settings are input and the network configuration is saved.
Assembly Instances section:
  • O indicates the originator—or I/O scanner—device
  • T indicates the target—or I/O adapter—device
Outputs T -> O Instance
A read-only value always set to 101.
Outputs T -> O Size
The maximum size reserved for local slave outputs, in bytes. An integer from 0...509. In this example, accept the default of 256.
Inputs O -> T Instance
A read-only value always set to 102.
Inputs O -> T Size
The maximum size reserved for local slave inputs, in bytes. An integer from 0...509. In this example, accept the default of 256.
Configuration Instance
A read-only value always set to 103.
Configuration Size
A read-only value always set to 0.
