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.

• Dual Communication: SW3-1
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: SW3-2
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.’

• Main/Sub Switching Control: SW3-3
The host PC or PLC can choose whether ‘Main’ or ‘Sub’ bus
is used when the switching control is set to ‘Host.’
In ‘Normal’ mode, ‘Main’ bus is normally used, while ‘Sub’
bus is when the main communication has failed.
Be sure to match this control mode for both network mod-
ules in dual communication mode.
