parity and stop bits. By definition, a hardware handshake
is not provided for.
– Click on the Save button.
– If you have connected only one barcode scanner, click on
the OK button in the EXAConnecT Setup window.
If you have connected a second or third barcode scanner, you
can configure it with the same work steps via the Device on
COM2 or Device on COM3 dropdown list field.
Connecting a Signal Lamp (see figure K)
You can connect a signal lamp 38 via the programmable logic
controller (PLC) or directly to the access point without a PLC.
Signal lamps and stack lights are not offered by Bosch.
Observe their operating instructions.
Signal lamps that require less than 10 W overall power can be
connected directly to the access point.
Otherwise the signal lamps require their own power supply.
– Remove the maintenance cover plate 8 (see "Connection
Work", page 26).
– Loosen the locknut 12 on the middle right-hand cable
gland 11 and feed the cables of the signal lamps through
the opening in the cable gland to the "OUT+" terminals on
the terminal strip.
The 24 V output is constructed with optocouplers for poten-
tial-free output of 24 V signals. Up to 3 A can be connected.
– Connect the 4 wires of the signal lamps to the "OUT+" ter-
minals.
The following configuration is recommended:
Terminal
Description
OUT1+
Signals that the "screwdriver is unlocked" e.g.
for the yellow signal lamp 43 at the "OUT1"
output.
OUT2+
Signals a flawless single screwdriving action
(individual result OK) e.g. for the green signal
lamp 45 at the "OUT2" output.
OUT3+
Signals a flawed single screwdriving action (in-
dividual result NOK) or a flawed series of
screwdriving actions (overall result NOK) e.g.
for the red signal lamp 46 at the "OUT3" out-
put.
The switch-on duration of the signal can be
configured in the Screwdriver Setup window,
via the Output Settings tab.
OUT4+
Signals a flawless series of screwdriving ac-
tions (overall result OK) e.g. for the blue signal
lamp 44 at the "OUT4" output.
The switch-on duration of the signal can be
configured in the Screwdriver Setup window,
via the Output Settings tab.
The signal ceases automatically once the next
single screwdriving action or the next series of
screwdriving actions begins.
– Feed the 4 wires of the signal lamps to an external power
supply 47 and from there to the corresponding "24 V+"
terminals of the "24 V-" output.
Bosch Power Tools
– When the connection work is completed, screw the main-
tenance cover plate 8 securely back onto the access point
using the two Phillips screws 2 .
– Retighten the locknut 12 on the middle right-hand cable
gland 11.
– Configure the signal lamps like a standard PLC.
PLC Connection (SPS)
The access point has 4 built-in 24 V inputs and outputs which
can be configured differently using the software.
Please note that the "IN n" 24 V inputs and the "OUT n" 24 V
outputs are only switching elements which have a potential-
free construction with optocouplers for 24 V signals. Up to 3
A can be connected. An external power supply is required
for the PLC switching functions.
– Remove the maintenance cover plate 8 on the voltage-free
access point by unscrewing the bottom two small Phillips
screws 2 (see figure A).
In this way, you can access the terminal strip 18
(see figure B).
– Loosen the locknut 12 on one of the middle cable glands
11 and feed the cables from and to the PLC through the
opening in the cable gland to the 24 V input or to the 24 V
output depending on the desired switching. See the exam-
ples listed below.
Example 1: 2 screwdrivers with different signals
(OK/NOK) or 4 screwdrivers with uniform signal (OK)
– Feed a cable from the positive 24 V output of the PLC ei-
ther to the "OUT1+" or "OUT4+" terminal of the 24 V out-
put of the access point and wire it in series via the "OUT+"
terminals.
– Feed a cable back from each "OUT-" terminal to a positive
input on the PLC.
The access point can now transmit the signals to the PLC for
two screwdrivers with different signals as follows:
– "OUT1-" reports the OK signal from screwdriver 0.
– "OUT2-" reports the NOK signal from screwdriver 0.
– "OUT3-" reports the OK signal from screwdriver 1.
– "OUT4-" reports the NOK signal from screwdriver 1.
The transmission is as follows for 4 screwdrivers with the
same signals, when for example only the successful screw-
driving tasks are to be recorded:
– "OUT1-" reports the OK signal from screwdriver 0.
– "OUT2-" reports the OK signal from screwdriver 1.
– "OUT3-" reports the OK signal from screwdriver 2.
– "OUT4-" reports the OK signal from screwdriver 3.
Example 2: 2 screwdrivers with different signals (OK and
NOK) are also unlocked by the PLC
– Feed two cables from positive 24 V outputs of the PLC to
the "IN1+" and "IN2+" terminal at the 24 V input of the ac-
cess point.
– Feed one cable each from the "IN1-" terminal and the "IN2-
" terminal to a negative input of the PLC.
The PLC can now, for example, unlock screwdriver 0 with a
signal to the "IN1+" terminal at the access point.
