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

bit 7 bit 2 bit 4

bit 1...8

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.
