Safety Notes

BIS L-4_ _ processor together with the other BIS L system components comprise the Iden­tification System and may only be used for this purpose in industrial applications corre­sponding to Class A of the EMC Directive.

Installation and operation are permitted by trained specialists only. Unauthorized modifica­tions and improper use will result in loss of the right to make warranty and liability claims.

When installing the processor, follow exactly the connection diagrams provided later in this
document. Take special care when connecting the processor to external controllers, espe­cially with respect to the selection and polarity of the connections including the power
supply.

Only approved power supplies may be used. For specific information, see the Technical
Data section.

When deploying the identification system, all relevant safety regulations must be followed.
In particular, measures must be taken to ensure that any defect in the identification system
does not result in a hazard to persons or equipment.

This includes maintaining the permissible ambient conditions and regular inspection for
proper function of the identification system and all the associated components.

At the first sign that the identification system is not working properly, it should be taken
out of service and guarded against unauthorized use.

This document applies to the processor BIS L-405-03_-00_-05-MU (Software version V1.2
and higher).

Introduction
BIS L-405 Identification System

This manual is intended to guide the user in installing and commissioning the components
in the BIS L-405 identification system, so that start-up time is reduced to an absolute
minimum.

Principle

Applications

System component
function

The BIS L-405 identification system belongs to the category of

This function enables applications in which information which has been pre-coded into the
data carriers can be read out and used for further processing.

The main areas of application include

– in production for controlling material flow

– in process materials organization.

The processor and the read head form a compact unit which is contained in a plastic
housing.

The data carrier represents an independent unit. It does not require line-fed power and
receives its energy from the integrated read head in the BIS L-405 identification system.
The read head continuously sends a carrier signal which supplies the data carrier as soon
as the latter has reached the required distance from the read head. The read process
takes place during this phase. The data are output in 8-bit blocks over 8 parallel data lines
and made available to the host system. These host systems may be:

– a control computer (e.g., industrial PC) having a parallel port, or
– a programmable logic controller (PLC).

read-only, non-contacting systems.

(e.g., for part-specific processes),
in workpiece transport using conveying systems,

for obtaining safety-relevant data,

Application

Signal description

Tag Present (TP): Indicates a data carrier in the field.
Address (ADR): Signal change outputs the next data carrier address.
Strobe (STR): This signal acknowledges the data output on the parallel interface.
ReStart: Deletes the data memory in the BIS L-405 and sets all data outputs to

D0..D7: Data outputs
When supply voltage is applied, the data outputs are in an undefined state for approx.

100 ms. Then they switch to 0. The first byte cannot be read until the ADR signal changes.

0. The data carrier is then read again or, if no data carrier is present,
only the data outputs are set to 0. This signal is also used to turn off
the read antenna. If two read heads are installed close together and
interfere with each other, this can deactivate one read head as long as
the other needs to be available.

Timing

Data carrier

Application
BIS L-405-... Processor

Detection of a new data carrier is indicated by the TP signal. The first data value is not
output until the ADR input signal changes. Each time ADR changes, the value of the next
address is given to the data outputs. As an acknowledgement of the data change, the
processor invertes the STR signal. Once the last byte is output, a change in ADR is
followed by a data value output of 0. Any further change to ADR does result in a change to
the STR signal, but the data remain 0. This is how the end of data can be recognized.
If the data carrier leaves the read head before all the data have been output, the data
remain stored for a subsequent data read. Before a new data carrier is recognized by the
read head, data transmission must have been completed.

If the next data carrier enters the read zone before the data have been picked up, the "Tag
Present" (Overflow) LED will indicate this by flashing. The data from the new tag are not
output, and a ReStart must be performed to resynchronize.

ReStart

If a ReStart is detected while a data carrier is in the active zone of the read head, the data
outputs are switched to 0 and acknowledged with STR. As soon as ReStart goes low
again, first the STR signal is inverted as acknowledgement and the data carrier is read out
again. From there the process is the same as for a newly detected data carrier.

With this function you can force a re-read of a data carrier.

Cable test

Timing

The cable test can be used to check the wiring of the outputs. "ReStart" is switched to
"high" and acknowledged with STR. The first data output D0 is not switched until the ADR
signal changes. Each time the ADR signal changes the next data output is switched. The
STR signal is switched to acknowledge the data output change. Once the last data output
D7 has been tested, a change in ADR results in the software version number (2 bytes)
being output. Any further change to ADR does result in a change to the STR signal, but the
data outputs remain at 0.

Application
BIS L-405-... Processor

The data lines from up to 8 BIS L-405 processor can be connected in parallel. Since no
data is output until there is a request ("ADR" signal), there is no signal collision among the
processors. It is imperative that you communicate with only one of these processors and
that the output protocol is completely finished before beginning communication with
another processor. If the data lines are wired in parallel, be sure that the data lines have at
least a 10 mA load. If necessary, install appropriate load resistors. If this recommendation
is not followed, the signal change on the data lines can be falsified, resulting in incorrect
data being sent.

CRC data check with
BIS L-405-037-... Processor

The BIS L-405-037-... processor checks for correctness of the data read using a CRC_16
checksum. This CRC_16 checksum is located in Byte 3 and Byte 4 of the data carrier. This
ensures especially high data integrity.

Initialize data carrier

In order to use the CRC_16 procedure, data carriers of type BIS L-10_-05/L must first be
initialized using a BIS L-60_ _ processor and the BISCOMRW.exe PC software. Only 3
bytes of user data are then available on the data carrier.

The BIS L-405-037-... processor can only be operated with initialized data carriers
of type BIS L-10_-05/L.

Data carriers of type BIS L-10_-05/L should not be used with the BIS L-405-033-...

CRC data check with
BIS L-405-037-...

If the BIS L-405-037... processor detects a data carrier with an incorrect CRC_16 checks­um, the output TP remains Low. The output STR is inverted to indicate the CRC error. The
"Tag present" LED flashes slowly.
The incorrect data can only be retrieved by changing ADR (see p. 8). The processor sets
the CRC_16 checksum to 0x00 0x00.

If you do not begin with retrieving the incorrect data, the new data will be output
the next time a data carrier with a correct CRC_16 checksum is detected.

Installation

Installation
BIS L-405

When installing two BIS L-405 on a metal base, there is normally no mutual interference. If
a metal frame is located in an unfavorable location, problems may result when reading out
the data carriers. In this case the read distance will be reduced to 80 % of the maximum
value.

Testing is recommended in critical applications!

Power TP

Metal frame

Once a data carrier has been processed in front of a read head, the next data carrier must
wait 400 ms before being introduced into the active field. This can be implemented by
means of a stopper. If a stopper is not used, there is a rule of thumb which takes into
account the conveyor speed. Distance between the data carriers in m = (0.4 x conveyor
speed in m/s) + 0.25 m.
Example: Conveyor speed = 1 m/s

Distance = (0.4 x 1 m/s) + 0.25 m = 0.65 m
This is an approximation for the worst case.
When using small data carriers and/or small read heads, the distance is reduced considerably!
