8645 - 57
Object 3000 hex - Write EEPROM
Writing of system-specific data to the EEPROM.
Length: 8 Bit
value Description
1 The actual module list (object 001 hex) is projected onto the nominal module list
(object 002 hex) or stored in the EEPROM.
A voltage reset is obligatory in order for the nominal module list to become valid.
2 The failsafe values (object 6206 hex, object 6207 hex), settings for input filter (object 6207) and
the activation and deactivation of the output messages (object 621F hex) are transmitted from the
RAM to the EEPROM of the Fieldbus module CANopen. The data must have previously been
transmitted to the module using the specified objects.
Object 3001 hex - Actual module list
List of the active subscribers switched on connected to the sub bus.
Length: 8 Byte
Structure of the module list:
Each module has a 4-bit identifier (see table Module identifier). The identifiers are enumerated in succession,
starting from the first expansion module M1 up to the last module (max. up to M16) and result in a hexadecimal
string. Here the intermediate modules are recorded first, then the RIO modules in their addressing sequence.

M1 M2 M M4 M5 M6 M7 M8 M9 M10 M11 M12 M1 M14 M15 M16
Module identifier: value [hex] Meaning
0 Empty/no module
1 Intermediate module
2 RIO module 8645
 RIO module 8640
Example:
CANopen FBM Intermediate module 1 Intermediate module 2 Intermediate module

RIO module 8645 Address 0
RIO module 8640 Address 1
RIO module 8645 Address 2
The right-hand example configuration results in the following list:
0x 1 1 1 2   0 0 0 0 0 0 0 0 0 0
RIO module 8645 Address 2
RIO module 8640 Address 1
RIO module 8645 Address 0
Intermediate module

Intermediate module 2
Intermediate module 1
Object 3002 hex - Nominal module list
List of the configured active subscribers connected to the sub-bus. Here the intermediate modules are
recorded first, then the RIO modules in their addressing sequence. The structure corresponds to that of the
actual module list under object 001 hex.
Length: 8 Byte
