Set Read Timeout
The Read Timeout is the maximum time allowed for the decode. The NJ/NX controller project has the Read
Timeout set to 2,000 milliseconds by default. This default value is defined by the value entered in the Initial Value
field for the HMI_ReadTimeout variable. This variable can be changed at runtime by the operator using the HMI
user interface. To aid in the setting of this variable, the last read time is accessible by monitoring the ReadTime
variable via the HMI or watching this value in SYSMAC Studio.
