7.2.2 Explanation of declaring the global variables:
For accessing communication RAM, global variables of data type
IEI_PLC_BMSTRUCT
are already declared for each option module slot in template "BM4_O_PLC01".
These are the following global variables (for example in PROPROG wt II):
_IEI_Ctrl_Slot_G AT %MB3.2258000 : IEI_PLC_BMSTRUCT;
_IEI_Ctrl_Slot_H AT %MB3.3258000 : IEI_PLC_BMSTRUCT;
_IEI_Ctrl_Slot_J AT %MB3.4258000 : IEI_PLC_BMSTRUCT;
_IEI_Ctrl_Slot_K AT %MB3.5258000 : IEI_PLC_BMSTRUCT;
_IEI_Ctrl_Slot_L AT %MB3.6258000 : IEI_PLC_BMSTRUCT;
_IEI_Ctrl_Slot_M AT %MB3.7258000 : IEI_PLC_BMSTRUCT;
If these variables are no longer in the PROPROG wt project, create – in dependence on
the slot (G to M) – the global variable
_IEI_Ctrl_Slot_G
(to
_IEI_Ctrl_Slot_M
) of
data type
IEI_PLC_BMSTRUCT.
At declaration of the global variables, this variable must be connected to the base address
of the BM4-O-IEI-01 option module.
