3.3 MNET Error and Status Data
The following topics list the register addresses that contain error and status data.
Use the Database View option from the ProLinx Main Menu to view the contents
of each register. The ProLinx Reference Guide provides the information on using
this option.
3.3.1 MNET Client Error/Status Data
The Client connection Error and Status Data areas are discussed in this section.
The error/status data table is located at the virtual addresses 6000 through 6009.
This data will be available through the Configuration/Debug Port or through the
Server driver, if requested by a remote Client.
The data area is initialized with zeros whenever the gateway is initialized. This
occurs during a cold-start (power-on), reset (reset push-button pressed) or a
warm-boot operation (commanded from the Diagnostics menu or immediately
after a new configuration has been downloaded).
Internal Database Address Description
6000 Command Request Count (total Client commands sent)
6001 Command Response Count (total command responses received)
6002 Command Error Count
6003 Number of Request Packets
6004 Number of Response Packets
6005 Errors Sent
6006 Errors Received
6007 Configuration Error Word
6008 Current Error
6009 Last Error
Registers 6000 through 6006 are counters and are shown as 16-bit signed
integer values in the range of -32768 to +32767. When a count exceeds +32767,
it will automatically rollover to -32768 and become less negative (increment) with
each additional count.
Register 6007, the MNET Configuration Error Word, is a bit-mapped value. Not
all bits are used; some are reserved for future use. The bit-map indicates the
following errors if specific bits are set to 1. Note that, since this is a bit map, if
multiple errors are present, the value displayed with be the sum of the values
shown in the chart for all of the bits set to 1.
Bit Decimal Value Description
0 0001 Reserved
1 0002 Reserved
2 0004 Reserved
3 0008 Reserved
4 0016 Invalid Retry Count (0 to 10)
5 0032 Invalid Float Flag (Y or N)
