• Data Allocation
: SW1, SW2
Data Allocation Type* must be assigned to each I/O mod-
ule 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.

‘Main’ (OFF) network and the other must be ‘Sub’ (ON)
network. For single communication, the network module
must always be set to ‘Main’ (OFF).

• Input Error Data
: SW3
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.’
