Data management - DDL buffer size

[Hudson]

Hello,

 I saw the DDL receive buffer max. size is 1000 bytes(see attachment), but my OpconData length is longer than 1000 byte, I tried to set the buffer to 5000KB,  but not available, still keep 1000 bytes in the TwinCAT, How to change the buffer size? need your help, thank you.

TwinCat can only show 1000 variables online in array.

Size from the buffer you change in OES/CPS for everry Message and one time for DDL connection

the problem is from station data manager addon,  in the configuration page, I set the target service to Opcon.Xml(see attachment),  there is no about buffer change option and I saw the buffer variable in the TwinCAT is a var variable ' _ddlMessageRecvBuffer : ARRAY [1..5120] OF BYTE;'. Can it be modified from CPS? thank you
