OPERATION MANUAL CompoBus/S

Checking Operations for CS-series, C200HX/C200HG/C200HE-(Z)E, and C200HS Master Units Section 6-2
Status Flag Functions The status flags have the following functions. These flags are automatically
cleared to 0 when the power is turned ON or the system is restarted.
Active Output Slave Flags
These flags indicate whether the corresponding Output Slaves are active
nodes in the CompoBus/S communications.
Flag status Meaning
0 (OFF) The corresponding Slave is not participating in communications.
(OFF if the Slave didn’t participate even one time.)
1 (ON) The corresponding Slave is participating in communications.
(Not changed even if the Slave is withdrawn from communications.)

Active Input Slave Flags
These flags indicate whether the corresponding Input Slaves are active nodes
in the CompoBus/S communications.
Output Slave Communications Error Flags
These flags indicate whether a communications error has occurred with the
corresponding Output Slaves.
Input Slave Communications Error Flags
These flags indicate whether a communications error has occurred with the
corresponding Input Slaves.
Note Input from Input Slaves and output to Output Slaves are enabled when the
CompoBus/S System is started up and the Active Node Flag corresponding to
the Slave turns ON. During actual operation, it is recommended to create ladder
programming that processes Slave I/O after checking that Active Node
Flags are ON and Communications Error Flags are OFF.
