If automatic addressing is used, no addresses may be used
between 1 and 14 (1 to E).

Setting the output data length for valves

The number of valve outputs can be set with bits 3 and 4 on the
S6 switch. Here there is an option to optimize the data range
needed in the controller with smaller valve units.
This setting only applies to the valves. Connected output
modules will be automatically recognized and added to the set
data length. The data length may be 4 bytes maximum.
Select the desired data length in accordance with the following
table.
Table 15: Selecting the output data length on the S6 switch,
bits 3 and 4
Data length Valve solenoids Bit 3
1 byte 8
2 bytes 16
3 bytes (default) 24
1)
4 bytes (24)
1)
The 4-byte mode enables conformity with 16-bit PLC systems. However,
only the first 3 bytes are transferred to the valve outputs. No more outputs may
be connected.
Changes are only taken over after a voltage reset. When
making changes, turn the DDL line supply voltage off and
then on again.
Further information on the addressing rules can be found in
the "DDL Drive & Diagnostic Link" system description
R499050030 (German), R499050031 (English).
