Operating The Ma 21 As Multinet Plus Slave; Managing Parameter Sets In The Ma 21 - Leuze electronic MA 21 Technical Description

6.2

Operating the MA 21 as multiNet plus slave

Initialising the network
• Set the appropriate slave address on the address selection switch (see also
chapter 3.1).
• The last slave address must be set on the address switch on the MA 30.
• Set the "operation" operating mode on the slaves.
• Switch on the voltage supply.
Acknowledgements on the terminal window:
i> 00 M
i> 01 s
i> 02 s

i> nn s
If, following the initialisation phase (approx. 30 s), not all slaves are yet operational or a time-
out (Addr.+T) has been output, please refer to chapter "Troubleshooting".
The connected slaves can now be contacted and configured from the master as if they were
individual devices.
The only difference is:
Contacting a slave
Within the network each data telegram must contain an ASCII address that specifies for
which slave the data are intended (cf. chapter 3.4)
Service mode: structure of the data frame.

Managing parameter sets in the MA 21

Parameter sets
The MA 21 is capable of managing three types of parameter sets
A "parameter set" refers to a memory area in the EEPROM that contains all settings (param-
eters) of a read station such as code type, number of digits, output formatting etc. in numer-
ical form. The BCL-Config configuration software facilitates menu-driven parameter setting.
For the software handling of the parameter sets, these are sequentially numbered from "0"
to "2".
1. Current parameter set ("0"):
parameter set that can be changed via an online or offline setup and that contains the
current settings of the MA 21.
