(3) Access via MELSECNET/H module
The following explains the accessible range and devices when access is made via a
MELSECNET/H module.
(a) Accessible range
This section provides a system configuration for access via a MELSECNET/H
module and a table showing accessibility of each target CPU.
1) System configuration
2) Accessibility table
The following table indicates whether access can be made or not for each
case.
The self station and connected station CPUs are all accessible.
: Accessible, : Inaccessible
* 1 Access is allowed when the MELSECNET/H module of the connected station is in the
MELSECNET/H mode.
* 2 Access is allowed when the MELSECNET/10(H) module of the connected station is in the
MELSECNET/10 mode.
