CHAPTER 6 – Functions and Methods
Note that the PLC may not be opened immediately after the statement has been executed. The
processed flag will be set at a later time when the operation has been completed. Therefore, if using
statements which require the operation to be completed create an On Condition script containing the
code to be executed after the PLC is opened with the 'processed' flag as the expression (this is
generally more efficient).
PLCCommsFailed
Syntax
returnstate = PLCCommsFailed("plcname")
Remarks
Argument
returnstate

Typical Example
IsFailing = PLCCommsFailed ("controlPLC")
The point IsFailing is set to true if the PLC called controlPLC is currently not communicating.
Otherwise it is set to false.
Note: This function returns to TRUE from the time when a communications timeout error
with the named PLC occurs, until successful communication with the PLC takes place.
PLCMonitor
Syntax
returnstate = PLCMonitor("plcname")
Remarks
Argument
returnstate
plcname
Typical Example
PLCMonitor("controlPLC")
The monitor dialog for the PLC called controlPLC is invoked. This dialog can be used to check PLC
status, change mode, etc.
