Changing EtherNet/IP settings

With the following products the settings can also be changed by ADS.

The Store Category must be defined in the System Manager for the setting. This is entered in the object 0xF800:2B "Advanced options" for all EtherNet/IP devices in the scanner or, for the slave interface, in object 0x8000:2B or 0x8010:2B for the optional 2nd slave.
If the corresponding flag is set, the IP address from the memory is used; if nothing is entered there the flag is ignored and parameters from the System Manager are used.

Changing EtherNet/IP settings 1:
Object 0xF800, Master Settings

ADS-Write command

AMSNetId:
In the case of the EL6652(-0010) this is the same as the EtherCAT AmsNetId; in the case of the supplement the AMSNetId is to be taken from the System Manager.
Port:
When using the EL6652(-0010) the port number is the corresponding EtherCAT Slave address of the terminal. In the case of the EtherNet/IP supplement the port number is to be permanently set to 0xFFFF.
IDXGRP: 0x0001F480
IDXOFFS: 0x00000000

After adjusting the settings a TwinCAT restart is to be carried out in the case of the supplement, as well as switching once to PreOp mode in the case of the EL6652. The new settings are then accepted on transition to the OP mode.

Setting for setting (4 bytes + object size (256 bytes))

Byte Offset 0: 0x45
Byte Offset 1: 0x23
Byte Offset 2: ObjIndex LoByte (e.g. 0x8000 for Slave 1 and 0x8010 for Slave 2 and 0xF800 for the Master)
Byte Offset 3: ObjIndex HiByte
Byte Offset 4-260: Data of the object (see object description below)

Setting for resetting (4 bytes)

Byte Offset 0: 0x00
Byte Offset 1: 0x00
Byte Offset 2: ObjIndex LoByte (e.g. 0x8000 for Slave 1 and 0x8010 for Slave 2 and 0xF800 for the Master)
Byte Offset 3: ObjIndex HiByte

Store Category
The "Store Category" defines, which *.tsm settings should be overwritten with settings from the remanent memory. To do this, bits 9 & 8 must be set accordingly under "Flags" in the System Manager project. In order to modify both, both bits must be set.
(Bit9=Cat2, Bit8=Cat1)

ADS-Read command

AMSNetId:
In the case of the EL6652(-0010) this is the same as the EtherCAT AmsNetId; in the case of the supplement the AMSNetId is to be taken from the System Manager.
Port:
When using the EL6652(-0010) the port number is the corresponding EtherCAT Slave address of the terminal. In the case of the EtherNet/IP supplement the port number is to be permanently set to 0xFFFF.

Slave:

IDXGRP: 0x44818000
IDXOFFS:ID of the slave interface
LEN: 256

The ID of the slave interface is taken from the setting in the System Manager, the ID is set by the system and can only be read.

Changing EtherNet/IP settings 2:
Object 0x8000: slave settings

Master:

IDXGRP: 0x4481F800
IDXOFFS:0x00000000
LEN: 256

The data are saved in the data array as described above.

Example for TwinCAT 2.11 R3 and EL6652 or EL6652-0010, reading and writing the IP setting:
