Do=More Warnings

[PLCGuy]

i am setting up a D2-DMH1 system. The WARNING light in on at the bottom of the software screen. I click on it and that brings up the large box showing the warning. Nothing specific. I then click on the option to config IO. The left pane opens showing all 4 Thermocouple modules in yellow. Clicking on them just tells me the rack is reporting there is a problem with the modules, again nothing specific. I suspect because I did not hook up the thermocouples, that is the warning. Shouldn't there be some SP bit set or something when there is a problem with the thermocouples? Should I be getting better info of what is causing the warnings?

The I/O System View consists of 2 panes - the top part is a tree that hierarchically lists out all your I/O.  The bottom (or right) pane is detailed information for the currently selected item in the tree.  Click on the module in the top pane, then look at the text in the bottom pane.  It should tell you something about the warning or error, in addition to online links to the specific module's .PDF manual and .PDF spec sheet.

There is a DWORD structure member in the LocalIOMaster heap-item structure .Slot0_31.  The corresponding bit of that DWORD (0..31) would be ON if the module in that corresponding SLOT was in ERROR.  So if slot 4 was in error, bit 4 would be ON, so then LocalIOMaster.Slot0_31 would equal 0x00000010 (remember that slots are 0-based and bit numbers are 0-based, so bit 4 is the 5th bit).

You can also look at Help Topic DmD0208 Memory Locations with System-Assigned Nicknames.  Specifically look at

bits: ST10, ST11, ST135, ST136, ST148, ST152, ST153
dwords: DST5 DST6 (these are just DWORD mappings of the ST1xx bits above)
