Cautions on design
•
For the status of each station in the case in which the PC CPU stops its operation or communica-
tion error has occurred in the data link, read thoroughly the contents of "5.
Data Link Processing Time" of the user manual of the master unit.
Construct an interlock circuit in a PC program so that the system can operate conservatively using
the communication status information (SB, SW).
If the interlock circuit is not correctly constructed, wrong output or malfunction may occur, and an
accident may occur at the end.
-
Receive data from the master station or a local station in which a data link error has occurred
1 )
Remote input (RX), remote output (RY)
The data varies depending on setting of the condition set switch on the unit and setting of the
input data (SW4) in a station in which a data link error has occurred.OFF: Data is cleared (All
OFF).
ON: The data just before an error occurred is held.
2 )
Remote register (RWw, RWr), remote input (RX), remote output (RY)
The data just before an error occurred is held without regard to setting of the SW4.
•
Never bind the communication cable together with the main circuit, the power cable, etc. Never
locate the communication cable near the main circuit, the power cable, etc.
Keep the communication cable by 100 mm or more from the main circuit, the power cable, etc. If
this distance is not kept, malfunction may occur due to noise.
