C200HW-SRM21-V1 Master Unit for CS-series, C200HX/C200HG/C200HE-(Z)E, and C200HS PLCs
Section 4-1
• Example: When a Slave with 16 inputs and 16 outputs is set to node num-
ber 3, it uses Output Slave 2 and 3, and Input Slave 2 and 3. Output Slave
2 and Input Slave 2 cannot be used by other Slaves.
An Analog Terminal uses 64, 48, 32, or 16 points. I/O allocations are shown in
the following table.
Do not allow allocations for the node numbers that are actually used to extend
beyond the words allocated to the Master Unit. Participation in communica-
tions will not be possible and the COMM indicator will turn OFF if the words
allocated to the Master are exceeded for either inputs or outputs.
Status Flag Functions
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The flag won’t change even if the node is withdrawn from the system.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.
