Access target
Alternative method
The access target is a network module on the own
station.
Configure the refresh setting so that a device of C Controller module, M, B, D, W, or ZR is refreshed by
a link device of a network module.
Use the MELSEC data link functions to access a device of C Controller module, M, B, D, W or ZR.
The access target is a network module on the other
station.
Configure the refresh setting for CPU module on the other station so that a device of C Controller
module on the other station is refreshed by a link device of a network module.
Specify the other station to the network number and station number in the MELSEC data link functions
to access a device of CPU module on the other station.
Access target
Alternative method
The access target is a network module on the own
station.
Open a communication line by specifying 'bus interface' to the channel in the mdOpen function.
Specify the module access device (DevSPG) to the device type in the MELSEC data link functions, and
access the area to which link devices are assigned
in the buffer memory of a network module.
The access target is a network module on the other
station.
Open a communication line by specifying the channel name corresponding to each network to the
channel in the mdOpen function.
Specify the other station to the network number and station number in the MELSEC data link functions.
Specify the module access device (DevSPG) to the device type in the MELSEC data link functions, and
access the area to which link devices are assigned
in the buffer memory of a network module.
