• Output references: Digital outputs or register outputs ≤ 512 points
(One register is 16 points)
(3) Digital references can be allocated as input references and register references
can be allocated as output references. Also, register references can be allocated
as input references and digital references can be allocated as output references.
c) The number of YENET 1600-D masters that can be connected depends on the num-
ber of the above I/O references that can be allocated by the CPU Module.
2) Number of Modules (in Slave Mode)
a) The YENET 1600-D slaves use I/O references, such as input relays, output coils, in-
put registers, and output registers, for communicating with the YENET 1600-D mas-
ter and other master devices that conform to the DeviceNet protocol. Therefore, I/O
must be allocated to the slot where the YENET 1600-D slaves are mounted, accord-
ing to the following regulations.
b) The maximum number of I/O points that can be allocated to each YENET 1600-D
slave is as follows:
(1) Either digital references (input relays) or register references (input registers) are
allocated as input references. Input relays and input registers cannot be allocated
together.
• Input references: Digital inputs or register inputs ≤ 64 points
(One register is 16 points)
(2) Either digital references (output coils) or register references (output registers) are
allocated as output references. Output coils and output registers cannot be allo-
cated together.
• Output references: Digital outputs or register outputs ≤ 64 points
(One register is 16 points)
(3) Digital references can be allocated as input references and register references
can be allocated as output references. Also, register references can be allocated
as input references and digital references can be allocated as output references.
c) The number of YENET 1600-D Modules (slaves) that can be connected depends on
the number of the above I/O references that can be allocated by the CPU Module.
