4.5 Measured values - CONTACTRON motor manager
EMM
An analog value is represented in a 16-bit data word in two’s complement format
(integer 16).
In addition to error code 8040h, which is generated by the EM-PB-GATEWAY-IFS if it is not
possible to communicate with the assigned slaves, other error codes are defined. They also
relate to the status of the measured value, not the state of the connected device.
The following example shows the scaling of the measured values and the assignment to the
PDC codes.
Table 4-21 Error codes
PDC Error
8001 h Out of measuring/representation range (overrange)
8002 h Open circuit, mains fault
8004 h No valid measured value available or invalid measured value
8010 h Additional error information available
8020 h PDC not activated
8040 h Module faulty or not ready to operate
8080 h Out of measuring/representation range (underrange)
