Data Allocation
: SW1, SW2
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 position,
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.

Functions & Data Allocation
Setting
•
Dual Communication
: SW3
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).
•
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 out-
puts ‘0.’
•
LED Function
: SW3
Functions assigned to the front RUN and ERR LEDs can
be selected.
