28: AS-INTERFACE MASTER COMMUNICATION
« FC4A MICROSMART USER’S MANUAL » 28-19
I/O Data for AS-Interface Master Module
The AS-Interface master module can process digital I/O data and analog I/O data. Digital I/O data can be a maximum of 4
digital inputs and 4 digital outputs per slave. Analog I/O data consists of 4 channels of 16-bit analog input or output data
per slave.
Digital I/O Data of Standard Slaves and Expansion Slaves
The digital I/O data for standard slaves and A/B slaves (sensors and actuators) on the AS-Interface bus are allocated to the
AS-Interface internal relays in the ascending order starting with slave 0. The input data image (IDI) for each slave is allo-
cated to M1300 through M1617, and the output data image (ODI) is allocated to M1620 through M1937. For example, in
the case of slave 3A, the input data is allocated to M1314 (DI0) through M1317 (DI3), and the output data is allocated to
M1634 (DO0) through M1637 (DO3).
