5.3.1.1

Transmit-PDO (from the IKM360R to the master)

PDO transfer from the IKM360R to the bus master can be initiated as a result of various
events:



asynchronous, controlled by an internal device timer



synchronous as a response to a SYNC telegram



as a response to an RTR message

The TPDO1 contains the slope long16. The transfer behavior of TPDO1 is determined via the
objects 1800h and 1A00h and is assigned to asynchronous transmission. Synchronous data
transmission is set at delivery. Other TPDOs are not supported.

COB ID

Byte 0 (LSB)

Byte 1 (MSB)

TPDO1
180h + Node ID

Slope long16

Table 9: TPDO message

Asynchronous data transmission

If a TPDO1 is to be sent cyclically, 254 (FEh) or 255 (FFh) must be entered in object 1800h,
sub-index 02h. The cycle time can be entered in milliseconds in object 1800h, sub-index 05h.
The TPDO1 will not be sent if the value 0 ms is written. The function is disabled. The minimum
value to be set is 1h (= 1 ms).

Synchronous data transfer

As delivered, the device responds to every SYNC Message received with the output of the
TPDO1 message. 1h is entered for synchronous transmission in object 1800h, sub-index 02h.
If a value n is entered between 1d and 240d (= F0h), the device will respond to every nth
SYNC message.

RTR

Queries can be sent via RTR (see chapter

) toTPDO1.

5.4

Parameter data exchange

5.4.1

Transmission of Service Data Objects (SDO)

Service data objects serve mainly device configuration via the directory of objects. SDOs in
the expedited Request/Response and in the normal Request/Response are supported.

The identifier is set to 11 bits and cannot be changed.

Two SDO services are available:



SDO (rx) (Master



Slave): 600h + Node ID



SDO (tx) (Slave



Master): 580h + Node ID

Two SDO services are available!
