The 16-bit value, Gateway Status, provides two pieces of information, the bottom 14-bits provide the current
state of all the major functions within the Hardy Gateway Module (HGM) and the top 2 bits of the 16-bit
value, are a cyclic “IO table count”, which will increment by a count of one every time a new “input table” is
generated, following a 0, 1, 2, 3 then repeat cycle. If the input table count value remains the same in two
consecutive reads from the HGM then the communication or the measurement function has failed and the
appropriate action needs to be taken. The bottom 14-bits reflect the status of all the major functions in the
HGM and should be used in conjunction with the “measurement update count”, and the individual status for
each WPM, to determine the health of the HI6600 system.
The Parameter ID; is an echo of the value sent in the output table, while the Parameter Value is the value
for the specified Parameter ID.
Portion of the INPUT table used for Weigh Processing Modules (WPMs)
A 32-bit value, Module Status, provides the current state of all the major functions within the selected Weight
Processing Module (WPM). The top 5 bits provide the module number selected in the output table, and the
next 3 bits are a simple cyclic “measurement update count”, which will increment by a count of one every time
a new measurement value is taken, following a 0 to 7 then repeat cycle. If this value remains the same in two
consecutive reads from the WPM then the communication or the measurement function has failed and the
appropriate action needs to be taken.

The bottom 24-bits reflect the status of all the major functions and should be used in conjunction with the
“measurement update count” to determine the health of the WPM.
Status Word bit 0 (0x0001): ADC Error
Status Word bit 1 (0x0002): WPM channel not enabled
Status Word bit 3 (0x0008): reserved

Status Word bit 8 (0x0100): Missing sample value
Status Word bit 9 (0x0200): reserved
Status Word bit 10 (0x0400): Failed to save to nonvolatile memory
Status Word bit 11 (0x0800): Module update in progress
Status Word bit 12 (0x1000): Failed to update module firmware
Status Word bit 13 (0x2000): Saving to nonvolatile memory
Status Word bit 14 (0x4000): IT test in progress
Status Word bit 15 (0x8000): Parameter ID not found
Status Word bits [23:16]: reserved
The Net and Gross Weight values are always provided, in the next two variables
The final value for the selected WPM is the Parameter RD Value, which is the read only value for the user
selectable parameter ID value set in the output table. If a 0x0000 is placed in the Parameter RDx ID value, or
the requested parameter does not exist a 0x0000 value will be returned.
