AC500 Modbus TCP No of Socket
In AC500 PLC it is mentioned in the document that there are 12 Sockets available for Modbus TCP/IP. When we set the Server Conections to 12 the System is allowing only 9 sockets for Modbus TCP.Remaining 3 sockets are reserved for system.
As pre the document the system should 12 sockets for Modbus TCP. We cannot increase the server connection more than 12 as it is not accepting in Automation Builder 1.1.0.
PLC Frimware Version (PM573-ETH): V2.4.4.
Is the information on the Help file is wrong or is there any other settings to do to use 12 sockets for Modubs TCP.
If you are using ETH_ICMP_PING blcok it will also cosnume socket,without any Port no. mentioned.
Also as per your attachement yu are consumed 5 out of 16,in that4 is system and 1 is Modus Server.
Please do give your program details also, sothat I think we can help you out if you are coming across any connectivity issue.
Also for better undestanding you can refer attched Manual.

I dont have such details of sockets. May be it is reserved internally and do remember your codesys and if any touch panel which you have connected will reserve sockets.
But in our project we are making loop of ETH_MOD_MAST block when no of slaves are exceeding more than 8.
You can take done bit of ETH_MOD_MAST and enable of second block throug it.
This is the way generally we are doing it.
Hope it helps you.
