11.7.1.1 Switching on and initialization the BMC-M-SAF-02
m
After being switched on, a basis initialization of the b maXX safe PLC is carried out
which is necessary for the further initialization. H9 (blue) will turn on once this basis ini-
tialization is complete.
m
The b maXX safe PLC module will then wait for the global ready message of the fol-
lowing modules:
n
Power supply module for the b maXX controller/safe PLC
n
Modules plugged in to the left of the b maXX safe PLC (such as the ethernet with
CANopen master module).
This phase is indicated by an LED pattern rotating to the left. In the process, four LEDs
will light up in the sequence H1 (green)
→
H5 (green)
→
H6 (red)
→
H2 (red)
→
H1
(green) etc. at an alternation of 500 ms. H9 (blue) is off again.
If the modules’ ready message is not given within a maximum of 8 seconds, H4 (red)
will turn on.
Troubleshooting and rectification
from page 83 onward in order to remedy the
cause of an error.
m
After the modules’ global ready message, the b maXX safe PLC will initialize the I/O
bus.
This phase is indicated by an LED pattern rotating to the right. In the process, four
LEDs will light up in the sequence H1 (green)
→
H2 (red)
→
H6 (red)
→
H5 (green)
→
H1 (green) etc. at an alternation of 500 ms.
If the I/O bus is cannot be initialized within a maximum of 8 seconds or an error appears
during the initialization of the I/O bus, H8 (red) will turn on.
Both of the above-described procedures can be completed very quickly, so that it is not
absolutely crucial to observe the related operating displays.
Afterward, a PROPROG communication can generally be carried out via the serial RS232
interface (X1) between the PC and the b maXX safe PLC.
Starting now, the PROPROG communication is also possible by means of TCP/IP, if a
module with ethernet functionality (such as the ethernet with CANopen master module)
is plugged in on the left side of the b maXX safe PLC and has been configured for com-
munication with the b maXX safe PLC.
m
If a boot project is present, the boot project will now be loaded (the boot project is read,
translated and stored in the SDRAM as an executable program code by Flash). The
loading of the boot project is indicated by a rapid blinking of LEDs H1 and H2.
The LEDs will show the following PLC-specific operation statuses at the end of the run-
up phase:
m
No project present, status “POWER ON”
→
LED H5 (green) and H6 (red) light up.
NOTICE!
If the modules’ ready message has not been given (H4 [red] is on), it will
not be pos-
sible
to run
any
user program code; a PLC error message will be generated. The
PLC will remain in “STOP” status.
