AS-Interface Master Module
The AS-Interface master module can be used with the all-in-one 24-I/O type and any slim type CPU modules to communi-
cate digital data with slaves, such as sensor, actuator, and remote I/O data.
One or two AS-Interface master modules can be used with one CPU module. The AS-Interface master module can con-
nect a maximum of 62 digital I/O slaves. A maximum of seven analog I/O slaves can also be connected to the AS-Interface
master module (compliant with AS-Interface ver. 2.1 and analog slave profile 7.3).
For details about AS-Interface communication, see page 24-1 (Advanced Vol.).
