A.3 Link relay (L area)
The L area is used when the computer link module (Cnet) or data link module (Fnet) is mounted
on the system. See the user’s manual of Cnet or Fnet for detail information.
A.3.1 When Cnet module is mounted
(When the Cnet module is mounted on the slot 0)

If the Cnet module is mounted on other slot than slot 0, please refer the following formula to
calculate the device number of L area.
Link relay number of RS-232C : L = ( 80 × n ) + [ the hexadecimal value of (m –1) ]
Link relay number of RS-422 : L = ( 80 × n ) + [ the hexadecimal value of (m –1) ] + 40
where, n : slot number on which the Cnet module is mounted. ( 0 ~ 7 )
m : frame number ( 1 ~ 64 )
