DESIGN PRECAUTIONS
• Refer to Chapter 13 in this manual for the status of each station when a communication
error occurred in the data link.
• When executing control (data changes) to an operating PLC, construct an interlock circuit in
the sequence program so that the entire system always works conservatively.
In addition, when executing control such as program changes and operation status changes
(status control) to an operating PLC, thoroughly read the manual and sufficiently confirm
safety in advance.
Especially in control from external equipment to a PLC in a remote place, problems in the
PLC may not be able to be handled promptly due to abnormality in data transfer.
Construct an interlock circuit in the sequence program. At the same time, determine the
actions in the system between the external equipment and the PLC CPU for protection
against abnormalities in data transfer.
