Chapter 4. FUNCTION BLOCK
4.3 Remote Function Block
4.3.1 Module Initialization :
Module Initialization function block is a program for the use in setting the location number of the slot on
which the communication module of A/D conversion module of the master station is mounted, the address
number of communication module which a remote I/O station has, the base location number, and the slot
location number, and specifying the available channel enable, a data type for A/D conversion, filter process
data, and average process data.
