Canceling Multifunction Object Processing - Omron NS Programming Manual

Operations When Communications Errors Occur
A communications error will occur if an attempt is made to read or write to a communications address
in an unconnected host. This function is used to set whether or not to continue with subsequent set
operations or to interrupt the operations when such a communications error occurs.
Interruption of operations can only be selected for synchronous communications. Operations will con-
tinue for asynchronous communications.
Continue operations
Example
Write Bit
Write Word
Write String

♦
Whether or not to continue operation after a communications error is set on the Expansion Set-
ting Tab Page in the Property Settings Dialog Box for Multifunction Objects.
♦
If a communications error caused by something other than communications with an unconnected
host occurs, the error message display will be followed by the System Menu. For this reason,
Multifunction Object processing will be canceled.

2-11-5 Canceling Multifunction Object Processing

More than one function can be executed using a Multifunction Object, but if an error occurs during
execution or if the execution of the operation is cancelled, Multifunction Object processing is stopped.
In such cases, the functions set for execution after the cancelled function will not be executed.

Write Word
Write String
