AB7007 max number of commands


Good afternoon,

I set up some modifications on a AB7007 gateway (Serial Modbus to Ethernet IP).
I don’t manage to add more than 55 commands (all the commands are read holding registers).

Is it possible to send more requests ?

Best regards.



How many bytes of memory are you using. There is a max of 500 bytes so that may be the wall you are up against.


Currently, we are using 260 bytes of memory.

When I try to add a new transaction in Anybus Configuration Manager, I got an error in the software. I have tried to set up a new configuration with this software, and I notice that I have the same error when I want to create more than 55 transactions.

Best regards.


Can you please send me your configuration file?


Here are the files.

Best regards.


Unfortunately, you are exceeding the file size by a combination of the transactions and nodes, but you can combine some of those transactions to make more space. Most of the ones I looked at are only reading 2 registers, and there is a separate transaction to read the next 2 registers, etc.
