Function Description
Parametering the BIS L-60_2 processor
Parameters,
Overview
There are 6 user parameter bytes stored on the Profibus master that can be used to activate
and deactivate various functions. Setting is done directly by linking a device to the Profibus
master. The parameter default settings are stored in the GSD file.
– CRC_16 data check:
If this function is activated, the correctness of the read or written data is ensured by a
CRC_16 data check (see
8).
– Dynamic operation on read/write head 1 or 2:
If dynamic operation is parametered, a read/write job can be sent even though there is no
Data carrier in the active zone of the head. As soon as a Data carrier passes by the head,
the command is immediately carried out.
– "Auto-Read” for read/write head 1 or 2:
If this function is activated, the processor reads out the first (max. 31) bytes from the Data
carrier starting at a defined start address as soon as the tag enters the active zone of the
read/write head. The start address must first have been stored in the processor’s EEPROM
with the command ID 07
Hex.
– 2nd bit header at end of in- and output buffer:
The 2nd bit header (factory setting) prevents data from being accepted by the bus as long
as it is not fully updated.
– Display state of the digital input in the bit header of the input buffer:
If this function is activated, the IN-bit displays the state of the digital input of the processor:
IN = 0 → digital input low; IN = 1 → digital input high

Function Description
Parametering the BIS L-60_2 processor
Parameters,
Overview
(continued)
– Reset BIS L-60_2 processor through the digital input:
If this function is activated, the processor is reset when the digital input is set to high.
– Selecting the data carrier type for processing:
Depending on the selection, either all or only specified data carriers may be processed.
– Output data carrier model and serial number:
If this function is activated, at CT Present the data carrier model and serial number (UID =
unique ID) are output.
At data carrier model BIS L-1_ _-01 the serial number is 4 bytes. At all other data carrier
models the serial number is 8 bytes.
If this function is activated and dynamic mode is not set, no read data are output at
CT Present, but rather only the model and UID.
