Fig. 45: ELX3312 - Process data
In the case of the EL3312, two sets of process data are available, one for each measurement channel.
• Underrange: Measurement is below range
• Overrange: Range of measurement exceeded ("Cable break" together with "Error")
• Limit 1*: Limit value monitoring 0: ok, 1: Limit value overshot, 2: Limit value undershot
• Limit 2*: Limit value monitoring 0: ok, 1: Limit value overshot, 2: Limit value undershot
• Error: The error bit is set if the process data is invalid (cable break, over-range, under-range)
• TxPDO State: Validity of the data of the associated TxPDO (0 = valid, 1 = invalid).
• TxPDO Toggle: The TxPDO toggle is toggled by the slave when the data of the associated TxPDO is
updated. This allows the currently required conversion time to be derived.
• CJCompensation: Externally measured temperature of the reference measuring point for cold junction
compensation
For detailed information on settings and operating modes, please read the chapter Process data and
