Setting up the slaves in the network
Initialising the network
After the parameters of the master setup have been set correctly, the network
should be ready for operation, i.e. after switching on the operating voltage all
slaves in the network should identify themselves with address and start char-
acter "S" to the connected service PC or the host computer (depending on
DIP switch 3
). If, following the initialisation phase (approx. 30 s), neither all
slaves are operational or a time out (Addr.+T) has been output, please refer
to chapter 5.1 "Troubleshooting".
The connected slaves can now be contacted and parameterised from the
master as if they were individual devices.
The only difference is:
Contacting a slave
In the network each data telegram must contain an
ASCII address
which
specifies for which slave the data are intended.

Managing the parameter sets in the MA 30/31
Parameter sets
This MA 30/31 is capable of managing three types of parameter sets.
"Parameter set" (abbr.: PS) refers to a memory area in the EEPROM which
contains in numerical format all settings (parameters) of the connector unit
MA 30/31 (with MA 30, also for the connected read station e.g. code type,
number of characters, output formatting etc.). For the software handling of
the parameter sets, these are sequentially numbered from numbers "0" to
"2".
Notice!
The BCL xx parameters mentioned in the following are relevant only in com-
bination with the connector unit MA 30.
1.
Current parameter set ("0"):
Parameter set which can be modified using online or off-line setup and
contains the current settings of the MA 31 or MA 30 and connected
BCL xx.
2. Customer-specific parameter set ("1"):
A parameter set stored in the MA 30/31 which can be constructed from
a copy of a current, valid parameter set. This is used particularly for sav-
ing to memory customer-specific settings independent of the read head
(BCL). Thus, when the BCL xx is exchanged, all read station (MA 30 +
BCL xx) settings are preserved.
3. Factory default parameter set ("2"):
Leuze standard parameter set which cannot be changed. The settings
correspond to the state upon delivery. A hardware RESET (see
chapter 4.6.2) resets the MA 30/31 and the BCL xx connected to the
MA 30 to the factory settings.
