Device Status Word (DSW): The 16 bits in <strong>the</strong> device status word are set as a result ofdetected error conditions occurring during <strong>the</strong> execution of an immediate command to<strong>the</strong> I/O module. The operating program is notified of <strong>the</strong>se error conditions by returningcondition code 1 to <strong>the</strong> processor. If o<strong>the</strong>r commands are attempted before resetting <strong>the</strong>DSW bits, condition code 1 continues to be returned to <strong>the</strong> program.The significant bits in <strong>the</strong> DSW and <strong>the</strong>ir meanings are:Significant Bits Meaning1 Command reject. The analog input module cannot execute <strong>the</strong>command. (For example, an interruption-causing command issuedto <strong>the</strong> device when it is disabled for interruptions.)14 Data check. The analog input module has detected a parity errorinvolving data. The operation that caused this condition usually canbe retried successfully if <strong>the</strong> error condition is intermittent.11-8 GA34-0003
