1734 AENT serie B point io and fanuc ethernet IP scanner

You'll find there's a 8 byte header on the input image. I suggest getting the 1734 Assembly manual from Rockwell. 1734-UM016B-EN-P The manual will also show the different configs. I'm working on the very same setup using 1734. So far I've been trying to connect via roboguide but with the same results. For now it's on the backburner due to travel but if/when I figure it out I'll definately post the results.

If you have access to RS Networx I would give it a try. I have a feeling there will need to be a config string created. To quote the setup manual; "Some EtherNet/IP adapters accept or require a non-zero
length configuration string. This configuration data can only be configured on the robot using a third party configuration tool such as RSNetWorx for EtherNet/IP"

This is for a 1734-AENT Series B point i/o with 4 1734-IBB and 4 1734-OBB connected to a fanuc via ethernet

Vendor ID:1
Device Type:12
Product Code:108
INPUT SIZE (bytes):8
OUTPUT SIZE (bytes):4
RPI (ms):20
Assembly Instance (Input):103
Assembly Instance (Output): 100
Configuration Instance: 102
Size: 0
Rack:89
Slot:1
Start Pt:1

You will need to add 3 bytes (one for each output card) to your number of input cards so it will be 9 bytes for the input size

INPUT SIZE: (bytes) 9
OUTPUT SIZE: (bytes) 3

EDIT: Correction

screen shot your settings both adv and regular, screen shot Ethernet IP page.

Is there anything else connected to the point i/o?

Thanks

I use these units all the time try this setting

Vendor ID:1
Device Type:12
Product Code:108
INPUT SIZE (bytes):17 base module uses 8 input bytes input cards are 1byte output card use 1byte 8+6+3=17
OUTPUT SIZE (bytes):3 output card use 1byte 1+1+1=3
RPI (ms):32
Assembly Instance (Input):101
Assembly Instance (Output): 100
Configuration Instance: 102
Size: 0

place the input modules in the rack as 1-6 first the 7-9 the output modules if not then setting below will not work
If input cards are not first then you must figure out new start pt based on how many output cards are before the input card example would be if 2 output cards came before the first input card the start pt would be 81 for the input card

Rack:89 For inputs
Slot:1For inputs
Start Pt:65 For inputs
DI RANGE [1-48]

Rack:89 For outputs
Slot:1 For outputs
Start Pt:1 For outputs
DO RANGE [1-24]

Also set IO AUTO CONFIG VARIABLE TO FLASE
AND AUTO UOP CONGFIG TO FALSE

The Allen Bradley unit 1734 also must be programmed for the proper chassis size it will not automatically set the chassis for you this must be done via ethernet with IE explorer

ahhh, i was forgetting the OB8 input bytes.
jrv5207 posted the config to remove the 8 byte header. Unless you want all of that status info, 103 will work the same only minus the 8 bytes on the input assembly. It'll help save some IO.

Attached is from the 1734-UM016B-EN-P Assembly Connections for POINT I/O and ArmorPOINT I/O EtherNet/IP Adapters User Manual that is available in pdf on google.

I need to configure 1794-aent Flex IO somebody could help me please. I don't have the data of assembly Instance. I have used one Plc Twincat 2 to configure.

You can add another connection.

I am having trouble getting this to work on my robot. I do have the Ethernet Scanner option.

Attached are screenshots of my config. I have one 1734-AENT and one card a 1734-OB8E. I tried different config sizes not sure what the setup is supposed to be at this point.

I have tried input size 2 output size 2

I have tried input size 10 output size 2

Input size 1 output size 1 and a whole bunch of others. I am looking for some guidance on this issue.
