b) The maximum numbers of points and registers that can be allocated for the M-NET
Module master (total of ports 1 and 2) are as follows:
(1) The maximum numbers of I/O points and registers that can be allocated for the
M-NET Module master (total of ports 1 and 2) are 64 input bytes and 64 output
bytes.
(2) Digital references (input relays) and register references (input registers) are allo-
cated to the master station in Y mode as input references. Input relays and input
registers can be allocated together.
• Digital input references (input relays) ≤ 256 points
• Register input references (input registers) ≤ 15 registers
(3) Digital references (input relays) are allocated to the master station in T mode as
input references. Input registers cannot be allocated.
• Digital input references (input relays) ≤ 256 points
(4) Digital references (output coils) and register references (output registers) are al-
located to the master station in Y mode as output references. The allocation of
output coils and output registers can be mixed.
• Digital output references (output coils) ≤ 256 points
• Register output references (output registers) ≤ 15 registers
(5) Digital references (output coils) are allocated to the master station in T mode as
output references. Output registers cannot be allocated.
• Digital output references (output coils) ≤ 256 points
c) The number of M-NET Modules that can be connected depends on the number of the
above I/O references that can be allocated by the CPU Module.
2) Installation Locations
a) An M-NET Module can be mounted to any slot of the Mounting Base of any Rack. It
will occupy one slot.
b) The following diagram shows where to mount an M-NET Module.
