32 I/O Slave
Using an Analog Terminal
An Analog Terminal uses 16, 32, 48, or 64 points. I/O allocations are shown in
the following table.
Number of points

64 points
SRT2-AD04: 4 inputs
48 points
SRT2-AD04: 3 inputs
32 points
SRT2-AD04: 2 inputs
SRT2-DA02: 2 outputs
16 points
SRT2-AD04: 1 input
SRT2-DA02: 1 output
Do not use words for the node number outside the words allocated in the
Master Unit. If words outside the specified output or input areas are used, the
Unit cannot participate in communications and the COMM indicator will not
turn ON.
The functions of the flags in the status area are described below.
• Active Output Slave Flags
These flags indicate which Output Slaves (0 to 15) are active nodes in the
system. When the corresponding flag is ON, the Slave is an active node.
All of these flags are reset when the power is turned ON or operation is
restarted.
0 (OFF): No communications participation
The node hasn't participated in communications even once.
1 (ON): Communications participation
The flag won't change even if the node is withdrawn from the system.
• Active Input Slave Flags
These flags indicate which Input Slaves (0 to 15) are active nodes in the
system. When the corresponding flag is ON, the Slave is an active node.
All of these flags are reset when the power is turned ON or operation is
restarted.
0 (OFF): No communications participation
The node hasn't participated in communications even once.
