Statusword
At word 14, the module returns a binary statusword where each bit indicates a state or
condition within the module. To interpret these states, note which bits are ON and use the
chart below to match each bit location to the state it represents.
For Example: If the statusword is 69 (45 hex) with a binary value of 0000 0000 0100
0101, bits 0, 2, and 6 are on. Bit 0 indicates an A/D conversion error, bit 2 indicates
status is ON and bit 6 indicates a shutdown error.
STATUSWORD bit positions refer to these variables:
