9.4 Link direct device
(1) Definition
MELSECNET/H network modules. Link direct devices are used to directly access the
link devices in the MELSECNET/H network modules.
At END processing of sequence program, a data refresh (data transfer) is performed
between the High Performance model QCPU.
(2) Designation method and application example of link direct device
(a) Designation method
Link direct devices are designated by network No. and device No.
(b) Application example
For link register 10 (W10) of network No.2, the designation would be "J2\W10"
• For a bit device (X, Y, B, SB), digit designation is necessary.
Designation example : J1\K1X0, J10\K4B0
