Specification CANopen Safety (IEC 61508) and CANopen for absolute encoder TBN/TRN 1 Intended use The rotary encoder TBN and TRN are intended for use in CANopen and in CANopen safety-relevant systems. The version TBN is a singleturn and the TRN is a multiturn absolute encoder. Thanks to its robust design, the encoder can be used in applications with harsh environmental conditions. Both encoders are designed for connection to a control system (PLC) which evaluates the measured values transmitted via the CAN bus and, in the event of error messages or the absence of process data, reacts...

Specification CANopen Safety (IEC 61508) and CANopen for absolute encoder TBN/TRN 7 CANopen functionality 7 CANopen functionality The CANopen interface enables operation via CANopen Standard and secure operation via CANopen Safety. The CANopen profile definition for the encoder is executed once according to CiA 301 application layer and according to EN 50325-5 framework for safety-relevant communication. The sensor system (position registration) is designed in redundant form. The sensor system's measured values are supplied to the self-monitoring controller on separate interfaces (SPI)....

Specification CANopen Safety (IEC 61508) and CANopen for absolute encoder TBN/TRN 8.2 Communication service data objects (SDO) 8.2 Communication service data objects For every modification of the encoder via SDO communication the device must be set preoperational first. It is recommended to wait for the response message of the encoder before sending another SDO message. Then you can be sure that the SDO message (e.g. parameterization) is worked out properly, save procedure (1010) as well. Or implement a time constant between the SDO commands which is long enough (e.g. 50 ms). Please don't...
