3.4.6.2 Event-controlled process-data objects, optionally with adjustable cycle
time
The event-controlled process-data must be linked to the individual system blocks, like the cyclical
process-data.
Here too, there are 8 bytes available for a data object.
A transmission of the output data follows:
• always, if a value has altered in the 8-byte user-data
• with the cycle time set under C0356/2 (CAN2_OUT) and 356/3 (CAN3_OUT)
You can set the appropriate monitoring times for the inputs under C0357/2 (CAN2_IN)and C0357/3
(CAN3_IN).
Event-controlled process-data telegram CAN1_IN to the drive
The process-data telegrams to the drive have a user-data length of 8 bytes, and the following
structure:
Byte 1
Identifier
Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8
Abb. 3-25 Event-controlled process-data telegram to the drive
Assignment of the user data:
Byte word assignment (16-bit) individual bit assignment double-word assignment (32-bit)
1 CAN1_nInW1_a (LOW-Byte) CAN1_bInB0_b 0 CAN1_bInB15_b CAN1_dnInD1_p
2 CAN1_nInW1_a (HIGH-Byte)
3 CAN1_nInW2_a (LOW-Byte) CAN1_bInB16_b 0 CAN1_bInB31_b
4 CAN1_nInW2_a (HIGH-byte)
5 CAN1_nInW3_a (LOW-byte)
6 CAN1_nInW3_a (HIGH-byte)
7 CAN1_nInW4_a (LOW-byte)
8 CAN1_nInW4_a (HIGH-byte)
Bytes 1-2 and bytes 3-4 can be simultaneously used as 32 individual binary/logic signals, as 2
separate 16-bit data-words (”quasi-analog signal”) or as one double-word (32-bit).
