12.1.7 Count mode
Count mode - process data mapping
Count 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 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
This diagnostics information must be acknowledged with the EXTF_ACK (process output)
control bit.
ERR_PARA
– 1: There is a 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_DO_PARAM, LOAD_CMP_VAL2, LOAD_CMP_VAL1, LOAD_PREPARE
and LOAD_VAL must not be set at the same time during the transfer. An incorrect value
was transferred with the control bits. Example: Values above the upper count limit or
below the lower count limit were selected for ”Load value direct” or ”Load value in
preparation”.
STS_LOAD Status of load function is set, if the Load function is running.
STS_DN 1: Status direction down.
