功能块输入 "Zone "需要一个Mc6DZoneType 类型的区段引用。

区段引用通过MC_BR_AsmGetZone_Acp6D 获取。输出区段引用的地址可直接用于功能块。

也可将此区段引用存储在Mc6DZoneType类型的过程变量中，以便日后使用。

 

功能块输入 "Zone "的地址分配

ST file:

IF(MC_BR_AsmGetZone_Acp6D_0.Valid ==  TRUE) THEN
MC_BR_ZonePowerOff_Acp6D_0.Zone:= ADR(MC_BR_AsmGetZone_Acp6D_0.Zone);

 

or

Var file:

VAR
    ZoneRef: Mc6DZoneType;
END_VAR

 

ST file:

ZoneRef:= MC_BR_AsmGetZone_Acp6D_0.Zone;
MC_BR_ZonePowerOff_Acp6D_0.Zone:= ADR(ZoneRef);

 

---

Function block input "Zone" requires a zone reference of type Mc6DZoneType.

The zone reference is retrieved with MC_BR_AsmGetZone_Acp6D. The address of the output zone reference can be used in the function block directly.

This zone reference can also be stored in a process variable of type Mc6DZoneType and used at a later time.

 

Address assignment to function block input "Zone"

ST file:

IF(MC_BR_AsmGetZone_Acp6D_0.Valid ==  TRUE) THEN
MC_BR_ZonePowerOff_Acp6D_0.Zone:= ADR(MC_BR_AsmGetZone_Acp6D_0.Zone);

 

or

Var file:

VAR
    ZoneRef: Mc6DZoneType;
END_VAR

 

ST file:

ZoneRef:= MC_BR_AsmGetZone_Acp6D_0.Zone;
MC_BR_ZonePowerOff_Acp6D_0.Zone:= ADR(ZoneRef);
