Section 4-3
Slave Registration
Function Procedure
When the Slave registration function is used, the Output/Input Slave registra-
tion table and registered Slave participation monitoring time must be set in the
Special I/O Unit DM Area, but the power must be turned OFF and ON again or
the Unit restarted to enable the settings.
The following example shows the procedure for using the Slave registration
function. (Information on other Slave registration function settings and con-
nections are omitted here.)

Output Slave Verifica-
tion Error: Slave Miss-
ing
OUT0
When the Slave registration
function is enabled, the bit cor-
responding to the node number
of the Output Slave that caused
the verification error (Slave
missing) will be turned ON.
Bits 00 to 15 correspond to
Output Slave node numbers 1
to 15. When the Slave that
caused the verification error
joins the network, the bit will
automatically turned OFF.
The bits in the Special I/O Unit
Area correspond to the node
numbers actually used by the
Slaves. Therefore, for Slaves
with 16 points or higher, the bits
other than those set for the
node number may also be
turned ON. For example, the
two consecutive bits used by a
16-point Slave or the four con-
secutive bits used by a 32-point
Slave may be turned ON at the
same time.

When the Slave registration
function is enabled, the bit cor-

of the Input Slave that caused
the verification error (Slave

Bits 00 to 15 correspond to
Input Slave node numbers 1 to

OUT0
When the Slave registration
function is enabled, the bit cor-
responding to the node number
of the Output Slave where a
verification error (unregistered
Slave in network) will be turned
ON.
Bits 00 to 15 correspond to
Output Slave node numbers 1
to 15.
Once a bit has been turned ON
the status will be held until the
power is turned OFF and ON
again or the Unit is restarted.

When the Slave registration

Once a bit has been turned ON
