FUNCTIONS AND PROGRAMMING
(b) Precautions for access to CC-Link module's self station devices and other
station programmable controller devices
When making access via a CC-Link module, provide interlocks depending on the
link status of the self station and other station.
1) Access to self station device
Create a user program that will provide interlocks to validate data writing to or
data reading from the self station device.
Data becomes effective only when the following conditions are satisfied.
Module error (Xn0) is OFF (normal)
Self station data link status (Xn1) is OFF (in data link).
Module ready (XnF) is ON (operable).
However, even if the above conditions are not satisfied, write/read processing
to/from the self station is normally terminated.
2) Transient access to other stations (other station programmable
controller CPU remote operation and device access)
Create a user program so that access will be made when the following
condition is satisfied, in addition to the interlocks for access to the self station
device.
Data link status of the access target station (Bits corresponding to a
communication target station of SW80 to 83, which are read from the self
station) is OFF (normal communication).
(c) Precautions for access to MELSECNET/H module's self station devices and
other station programmable controller devices
When making access via a MELSECNET/H module, provide interlocks depending
on the link status of the self station.
1) Access to self station device
Create a user program that will provide interlocks to validate data writing to or
data reading from the self station device.
Data becomes effective only when the following conditions are satisfied.
Module status (SB20) is OFF (normal)
Baton pass status (self station) (SB47) is OFF (normal).
Data link status of self station (SB49) is OFF (in data link).
However, even if the above conditions are not satisfied, write/read processing
from/to the self station is normally terminated.
2) Transient access to other stations (other station programmable
controller CPU remote operation and device access)
Create a user program so that access will be made when the following
condition is satisfied, in addition to the interlocks for access to the self station
device.
Baton pass status of the access target station (Bits corresponding to the
communication target station of SW70 to 73, which are read from the self
station) is OFF (normal communication).
Data link status (Bits corresponding to the communication target station of
SW74 to 77, which re read from the self station) is OFF (normal
communication).
