Name
firmwareRestart
Description
Reboots the interface when set to a non-zero value. Invoking this function will cause loss of
communications. The interface will attempt to send a response to an SNMP set request before
restarting. Due to the nature of SNMP, receipt of such a response by the manager is not
guaranteed. Invoking this feature via HMI will cause the HMI to become inoperable until the
interface has completed re-initialization. A successful restart can be verified by reading the
sysUpTime variable. sysUpTime returns to 0 following a restart.
A restart via SNMP may adversely affect an HMI connected host processor. Care should be taken to
insure that a host processor attempting to communicate via HMI during reset can recover from the
HMI’s failure to respond and, further, that the host processor will continue to function properly
following reinitialization of the MI variables to their default or persistent values.
