3.4. Data transmission properties

For reasons of compatibility, within the complete multicon system the data amount is always the same (see table
in chapter 6), no matter how many digits are provided in the display. For example, command "R" (read actual
value) comprises a transmitted data amount of 6 bytes, but only 5 digits are indicated in the

3.5. Broadcast commands

Some specific commands are designated so-called broadcast commands. As soon as the master broadcasts a
command to identifier 99, the command is addressed to every N 150 in the network. Each individual spindle
position display will accomplish the respective command but will not respond any confirmation to master.

3.6. Data saving

Specific parameters are saved in EEPROM (1.000.000 writing cycles). Data saving is via interface upon every
parameter transmission to SPA.
Important:
There should not be a cyclic transmission of these parameters to SPA but only if necessary, for example in case
of parameter alteration. The relevant parameters saved in EEPROM are listed in the charts in chapter
"Command explanations" or "Overview on commands".

4. Command explanations

4.1. General information

The following is describing the individual interface commands broken down into the four groups below:
