17.6 Read and write Buffer Memory of Special Function Module
Special function module No.
Specify the last input/output signal (I/O address) of the special function module. (Specify the upper 2-digit in 3-digit
representation.)
Convert the numerical value to 2-digit ASCII code (hexadecimal), and send it from the upper digits.
■Special function module No. which occupies 1 slot
Special function module No. is the upper 2 digits of the input/output signal (I/O address) of the last number represented with 3-
digits on the slot where the module is mounted.
■Special function module No. which occupies 2 slots
For a special function module which occupies two slots, the number of occupied points for each slot is fixed for each module.
Special function module No. specified for the operation procedure is the upper 2 digits of the input/output signal (I/O address)
of the last number represented with 3-digits of the slot assigned as a special function module on the slot.
For details of the assigned slot for each module, refer to the manual of the modules.
Ex.
A module that assign the first part of the slots as empty slots (AD72, A84AD, etc.)
Ex.
A module that assign the last part of the slots as empty slots (A61LS, etc.)
Ex.
A module in which both assignment of special function module and I/O assignment exist (A81CPU)
