4. Assignment of CC-Link compatible I/O
1
Outline
n NOTE
SIW(n) and SOW(n) are handled as numerical data of word with no sign. SID(n) and SOD(n) are handled as numerical data of double words with a sign.
n NOTE
The dedicated input of the STD.DIO connector provided on the controller will be disabled except for an interlock signal (DI 11). When the external 24V monitor control of system parameters is disabled, the interlock signal (DI 11) will also be disabled.
The I/O expressions used in the robot controller’s program language and the I/O expres- sions for the remote device stations differ. The correspondence is shown below.
