Codesys 3.5 Bacnet

CODESYS
1

In CODESYS 2.3, I used the following method to store RETAIN values in BACnet objects:

PROGRAM BACNET_Retain_320
VAR
    FbBY2305_320_001_RT900_DMS_CMD : FbRetainSetpoint_MV;
    FbBY2305_320_001_RT900_SW_S_SP : FbRetainSetpoint_AV;
    FbBY2305_320_001_RT900_SW_W_SP : FbRetainSetpoint_AV;
    FbBY2305_320_001_RT900_DAYS_SP : FbRetainSetpoint_AV;
END_VAR

VAR RETAIN PERSISTENT
    Retain_BY2305_320_001_RT900_DMS_CMD : typRetain_MV;
    Retain_BY2305_320_001_RT900_SW_S_SP : typRetain_AV;
    Retain_BY2305_320_001_RT900_SW_W_SP : typRetain_AV;
    Retain_BY2305_320_001_RT900_DAYS_SP : typRetain_AV;
END_VAR

FbBY2305_320_001_RT900_DMS_CMD(
    BACNET_MULTISTATE_VALUE := BY2305_320_001_RT900_DMS_CMD,
    typRetain_MV := Retain_BY2305_320_001_RT900_DMS_CMD);

FbBY2305_320_001_RT900_SW_S_SP(
    BACNET_ANALOG_VALUE := BY2305_320_001_RT900_SW_S_SP,
    typRetain_AV := Retain_BY2305_320_001_RT900_SW_S_SP);

FbBY2305_320_001_RT900_SW_W_SP(
    BACNET_ANALOG_VALUE := BY2305_320_001_RT900_SW_W_SP,
    typRetain_AV := Retain_BY2305_320_001_RT900_SW_W_SP);

FbBY2305_320_001_RT900_DAYS_SP(
    BACNET_ANALOG_VALUE := BY2305_320_001_RT900_DAYS_SP,
    typRetain_AV := Retain_BY2305_320_001_RT900_DAYS_SP);

Now I am using CODESYS 3.5 SP19 Patch 7 with the ** WagoAppBACnet Library (version 1.1.1.2)**. How can I achieve the same functionality (retain BACnet values like Present_Value) using this setup?

Can you provide an example of how to make a FbAnalogValue_medium retain its rPresentValue across power cycles?
