Function Description
Parametering the BIS C-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
9).
– Simultaneous data transmission for both read/write heads:
With simultaneous data transmission shorter read/write times can be achieved depending
on the amount of data to be read/written and the type of controller.
– 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
– Reset BIS C-60_2 processor through the digital input:
If this function is activated, the processor is reset when the digital input is set to high.

Parametering Bytes
User-Parameter Bytes
For parametering all 6 bytes must always be transferred in Hex. Only the bits mentioned
may be changed. No guaranty will be given for the proper functioning of the
BIS C-60_2 if any of the other bits are changed.
The default values (factory setting) for the 6 bytes are:
1st byte 2nd byte 3rd byte 4th byte 5th byte 6th byte
Hex 00 80 00 82 00 02
Binary 000
00000 10000000 00000000 10000010 00000000 00000010
bit 6
bit 4 bit 7 bit 2 bit 4 bit 1...8
bit 5 bit 5 bit 8 bit 5
bit 8
The bits which serve for parametering have the following functions:
1st byte, bit 5 Activate CRC_16 data checking
2nd byte, bit 5 Dynamic mode on read/write head 1
(for effects on read/write times, see
54/55)
2nd byte, bit 4 Activate Auto-Read function starting at specified address after CT-
Present for Head 1 (the number of bytes read depends on the selected
buffer size minus bit headers for Head 1)
4th byte, bit 8 Arrange a 2nd bit header at the end of the input and output buffers
If this function is selected, then the minimum size of both buffers is 4 words (8 bytes) each.
Please note the basic procedure on
14 and 29...35 and the examples on pages 36...53.
