LED Indicators ....................................................................................... 34
The module provides information on diagnostics and troubleshooting in the following
forms:
LED status indicators on the front of the module provide general information on the
module's status.
You can view status data contained in the module through the Configuration/Debug
port or the Ethernet port, using the troubleshooting and diagnostic capabilities of
ProSoft Configuration Builder (PCB)
.
You can transfer status data values from the module to processor memory and can
monitor them in the processor manually or by customer-created logic. For details on
Status Data values, see Error Status Table.
4.1
Reading Status Data from the Module
The MVI46-PDPS module returns a 20-word Status Data block that can be used to
determine the module’s operating status. This data can be located in the module’s
database at registers at the location specified in the configuration. This data is
transferred to the SLC processor continuously with each read block.
4.1.1
Definition of Module’s Extended Diagnostics Data
The Extended Diagnostic Data is reported during startup and initialization sequence
when the master requests diagnostic data from the module. The Extended Diagnostics is
"Device Related" type providing status data (the extended diagnostic bit 3 in standard
diagnostic byte 1 is set = 0). The data length is normally 14 (0E) bytes displayed in the
following format:
