Creating data areas in the symbol table

Requirements
Hardware has been successfully configured.
Your modules do not have any errors after the hardware configuration is
loaded.
Addressing channels
The channels in the process image are addressed as described in the online help
for the "Pcs7Cnt1" driver block (FB1833). In the following example, the start
address 512 is used.
The start address can be found in the HW configuration.
Note
It is the first address displayed in the input range.
Channels in the process image:
Channel 0: Start address + 8 bytes = EW 520
Channel 1: Start address + 10 bytes = EW 522
Channel 2: Start address + 12 bytes = EW 524
Channel 3: Start address + 14 bytes = EW 526
You can find information on the use of DWORD data formats in chapter 3.6.9.
Note
Channels outside of the process image:
Channel 4: Start address + 4 bytes = EW 516
Channel 5: Start address + 5 bytes = EW 517
Channel 6: Start address + 6 bytes = EW 518
Channel 7: Start address + 7 bytes = EW 519
The following applies for the addressing of these channels (4-7): start address of
the counter module + channel number.
