Modbus TCP limited to number of simultaneous slaves to 10?

I read in one of the posts that you can have as many masters in a modbus TCP environment but only 10 slaves simultaneously. Is this correct so if I had 50 slaves I would require (5) modbus tcp ethernet ip anybus gateways?

Also just double checking if I have a devicenet network i need to connect to and other network would be ethernet ip the gateway would have a devicenet terminal block and on the other end there will be (2) ethernet ports to communicate to my plc? also up to 63 devicenet slaves?

what would you recommend I use if im wrong. thank you

Hello @lkl8082 ,

What anybus device are you using? Can you share the article number? Our modbus TCP master is capable of connecting to 64 slave. This may be a device limitation, the modbus TCP protocol is not limited to 10 slave. You can see details regarding what connection can be made from the the product page.

Again, what is the article number for the devicenet device? Most of our EIP slave interfaces offer 2 ports on the ethernet/ip interface. The deviceNet interface uses a phoenix connector as seen in the installation guide. ABX-DEVM.indd (anybus.com)
