Analog I/O Data of Analog Slaves
The I/O data for a maximum of seven analog slaves (four channels for each slave) on the AS-Interface bus is stored to AS-
Interface data registers in the CPU module. The analog slave addresses (1 to 31) are in the ascending order. The input data
for each analog slave is allocated to data registers D1700 to D1731, and the output data is allocated to D1732 to D1763.
The AS-Interface master module is compliant with analog slave profile 7.3.
• The maximum number of analog slaves that can be connected to the AS-Interface bus is seven. Do
Caution
not connect eight or more analog slaves to one bus, otherwise the slaves will not function correctly.
• When data registers D1700 through D1731 allocated to analog inputs contain 7FFF, do not use this
data for programming, because this value is reserved for a special meaning as follows:
Unused channel on a slave allocated to analog slave. (For a channel on a slave not allocated an
analog slave, the corresponding data register holds an indefinite value.)
Data overflow.
Communication between the master and analog slave is out of synchronism.
• When using analog slaves, read the user's manual for the analog slave to process the data properly.
