Peripheral address:
n This parameter is available in CPUs from VIPA or in S7-300 CPUs from Siemens.
n Configured base address of the input area of the System SLIO frequency measure-
ment module, which is to be read from. The address is hexadecimal.
n (Example: Address 100: LADDR_IN: = W#16#64)
HW identifier:
n This parameter is only available in S7-1500 CPUs of Siemens.
n Enter at HW_ID the HW identifier, with which your module can be addressed accord-
ingly.
