12.1.10 Measurement mode
Measurement mode - process data mapping
Measurement mode - process input data
n = offset of input data; depending on extension of station and the corresponding fieldbus.
NOTE
With PROFIBUS, PROFINET and CANopen, the I/O data of this module is localized within
the process data of the whole station via the hardware configuration tool of the fieldbus
master.
For DeviceNet, EtherNet/IP and Modbus TCP a detailed mapping table can be created with
the TURCK BL20 DTM in PACTware.

Bit Description
ERR_24Vdc short-circuit sensor pwr supply
This diagnostics information must be acknowledged with the EXTF_ACK (process output)
control bit.
ERR_DO Short-/open circuit/excess temperature at the output DO1
ERR_PARA
– 1: Parameter error ERR_PARA is a group diagnostics bit. With the separate diagnostics
message bits 3…6 describe the parameter errors in more detail.
– 0: The parameter definition is correct as per specification.
RES_STS_A
– 1: Resetting of status bits running. The last process output telegram contained: RES_STS
= 1.
– 0: The last process output telegram contained: RES_STS = 0.
ERR_LOAD 1: Error with load function
Control bits LOAD_UPLIMIT and LOAD_LOLIMIT must not be set at the same time during
the transfer. The value of LOAD_UPLIMT and LOAD_LOLIMIT was selected outside of the
permissible range.
