Communications Functions Section 1-9
Note 1. When the maximum number of CompoBus/S nodes is set to 16, IN8 to
IN15 can be used as work bits.
2. CompoBus/S Terminals with less than 8 points are allocated bit addresses
from either 0 or 8.
3. CompoBus/S Terminals with 16 points can be set for only even number ad-
dresses.
Status Flags The communications status between CompoBus/S terminals is output
through AR04 to AR07 Slave Add Flags and Slave Communications Error
Flags.
Note 1. IN0 to IN15 are the input terminals and OUT0 to OUT15 are the output ter-
minals.
2. When the maximum number of CompoBus/S units is set to 16, IN8 to IN15
and OUT8 to OUT15 cannot be used.
3. The Slave Add Flag turns ON when a slave joins the communications.
When the power to the CPU Unit is turned OFF and ON again all bits will
turn OFF.
4. The Slave Communications Error Flag turns ON when a slave participating
in the network is separated from the network. The bit will turn OFF when
the slave re-enters the network.
