”Process interrupts lost” diagnosis
For the modules
• 2DI 24 VDC High Feature (6ES7 131-4BB00-0AB0)
• 4DI 24 VDC High Feature (6ES7 131-4BD00-0AB0) and
• 4DI 24--48 VUC High Feature (6ES7 131-4CD00-0AB0)
the ”Process interrupt lost” diagnosis is not currently available. This function will be
implemented in a future product level of the IM151-3 PN.
Note
Process interrupts should not be used for process-related purposes (such as
periodic generation of process interrupts), because they may be lost in the overall
system.
