8.3.3.2 Class 2 Functionality
This attribute controls the Class 2 functionality regarding diagnostic data and operating mode.
0 Disable Not enabled (Class 1)
1 Enable Enabled (Class 2) Default setting
Mode Class 1 resets any scaling enabled. The encoder then uses the default set-
ting for the scaling parameter.
8.3.3.3 Commissioning Diagnostics Control
Encoder profile-specific designation for the behaviour of the device at standstill, regarding addi-
tional diagnostic data (extended DP diagnostics). The input value for rotary encoders
remains
without
importance, since the diagnostic function is always enabled. For linear encoders, the
value is optionally adjustable (default setting is (1) = enabled).
8.3.3.4 Scaling Function
The physical resolution of the encoder can be changed, using the scaling parameters
• Measuring Units per Revolution -- (Octet 10-13)
• Total Measuring Range -- (Octet 14-17)
if this attribute is enabled. Otherwise, there will be no scaling.
0 Disable not enabled
1 Enable enabled Default setting
8.3.3.5 Enabling the SSA Service
Optional function to change the subscriber address by telegram "DDLM_Set_Slave_Address"
(SAP 55).
0 OFF Function not enabled Default setting
1 ON Function enabled
A change of address by telegram is only accepted if "EEPROM" is selected as
the address source (see octet 9, bit 7).
8.3.3.6 Selection of the Address Setting
This attribute defines the source of the address of the slave (encoder). The information is only
evaluated during power-up. The setting is stored in the EEPROM.
A change of the attribute only becomes effective at next power-up.
0 OFF DIP switch Default setting
1 ON EEPROM
A change of the value to "EEPROM" may cause the allocation of a new address
for this subscriber at next power-up. This depends on which value was param-
eterised before (Set_Slave_Address) and stored in the EEPROM. -- The default
address is "1".
