Section 4-3
• When an even node number has been set:
Bits 0 to 3 are used and bits 4 to 7 are not used.
Example: When a Slave with 4 outputs and 4 inputs is set to node number 2,
the rightmost 4 bits (bits 0 to 3) of the area for node number 2 for both output
and input are used.
Slave with 32 Outputs or 32 Inputs
The Slave is treated as four node numbers for output or input and is allocated
2 consecutive words, as follows:
• When an odd node number has been set:
Uses (node number setting
–
1) to (node number s 2)
• When an even node number has been set:
Uses (node number setting) to (node number s 3).
Example: When a Slave with 32 outputs is set to node number 1, it uses the
area assigned for Output Slave 0 to Output Slave 3. The area for Output Slave
0, 2, and 3 cannot be used for another Output Slave.
Slave with Mixed I/O (16 Outputs and 16 Inputs)
Slaves that have both outputs and inputs are also assigned a single node
number, so the same node number is used for both outputs and inputs, and
each is regarded as two node numbers. Outputs and inputs are allocated to
the same words, as follows:
• When an odd node number has been set:
Uses (node number setting
–
1) and (node number setting)
• When an even node number has been set:
Uses (node number setting) and (node number s 1).
• Example: When a Slave with 16 inputs and 16 outputs is set to node num-
ber 3, it uses Output Slave 2 and 3, and Input Slave 2 and 3. Output Slave
2 and Input Slave 2 cannot be used by other Slaves.
