• Data Allocation: SW1, SW2
5
Data Allocation Type* must be assigned to each I/O module
position to specify how many data areas (four types) are to
be occupied by each.
Two bits from SW1 and SW2 are assigned to each posi-
tion, and data areas can be specified from the module No. 1
through 8. Setting for No. 9 and later modules is identical
to No. 8.

• Dual Communication: SW3-1
When two network modules are mounted, one must be
'Main' (OFF) network and the other must be 'Sub' (ON)
network. For single communication, the network module
must always be set to 'Main' (OFF).
SW
SW3-1
• Input Error Data: SW3-2
Hold: When the communication from an input module is lost
due to the input module error, the network module holds the
signal and stands by until the communication recovers.
Set to '0': When the communication from an input module
is lost due to the input module error, the network module
outputs '0.'

Note: Be sure to set unused SW3-3 and 3-4 to OFF.
