*2. Refer to the specifications of the related series for the
Data Allocation Type of I/O modules.
• Dual Communication
: SW3
When two network modules are mounted, one must be
‘Main’ (OFF) network and the other must be ‘Sub’ (ON) net-
work. 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.’

must be assigned to each I/O module
slot 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 position,
and data areas can be specified from the slot No. 1 through
8. Setting for No. 9 and later slots is identical to No. 8.
