The application problem of the SNMP client function block

PLCnext Technology & PLCnext Controls

We is developing a solution for network visualization. The controller AXC F 2152 will be used.The requirement from the customer is below:

                                               1. About 200 managed switches are monitored，every controller(AXC F 2152) monitor about 20~30 managed switches.
                                               2. About 80 variables(OID) is monitored in each managed switches.

The problem is that the number of variable bindings in SNMP Client function block limit to 2. The data definition is that SNMP_ARR_VAR_BIND_LIST : ARRAY[1…2] OF SNMP_UDT_VAR_BIND. This means we need to poll several times to read all the data we want. It takes a long time to do it. I know that the data length of UDP communication in PLCNext is more than 1460. Theoretically, the number of variable bindings can be more. Would you like to change the code for us?

Hello,

I am facing exactly the same issue described in this thread regarding the SNMP Client limitation.

The data structure:
SNMP_ARR_VAR_BIND_LIST : ARRAY[1..2] OF SNMP_UDT_VAR_BIND
still limits the request to only 2 variable bindings.

I need to increase the SNMP_ARR_VAR_BIND_LIST array up to 10 elements. Would you like to change the code for us as well?
