Chapter 9 – Bus Monitor Functions
9.1.9 ApiCmdBMIni
Prototype:
AiInt16 ApiCmdBMIni ( AiUInt32 ul_ModuleHandle, AiUInt8 biu );
Driver Command:
API_BM_INI (0xB0)
Purpose:
This function is used to initialize the chronological Bus Monitor of the AIM board.
Execution of this function will:
(1) Enable the capturing of all RT Transmit and Receive Subaddresses and Mode
codes. (This can later be modified using the ApiCmdBMFilterIni function.)
(2) Set the BM Status Word Exception Mask to 0x07FF such that all error/status
bits in the Status word will be evaluated by the Bus Monitor for triggering and/or
BM Error Word (Status word exception) indication. (This can later be modified
using the ApiCmdBMSWXMIni function.)
(3) Disable the Illegal Command/Mode code tagging feature of the Bus Monitor for
all RT Transmit and Receive Subaddresses and Mode codes. (This can later
be modified using the ApiCmdBMIllegalIni function.)

equal to API_OK the function ApiGetErrorDescription can be used to obtain an
error description.
