Ethernet/IP bus interface for DIOLINE20 Vers. 1.00
Functional description
29/45
4.3.3.1.1.3.4 L-Bus technical data set
Number of supported L-
Bus substations: N = 1 … 10 (N
max
)
Maximum total length of input data: L
imax
= 19 + N
max
*8 = 99 bytes
Actual length of input data:
L
iact
= <Content of Class ID #120, Instance ID #0, Attribute ID #8> bytes
Maximum total length of output data: L
omax
= 1 + N
max
*8 = 81 bytes
Actual length of output data:
L
oact
= <Content of Class ID #120, Instance ID #0, Attribute-ID #9> bytes
4.3.3.1.1.3.5 Heartbeat
The following specifications apply to the heartbeat counter:
-
Output data: incremented by one on each I/O cycle and reset to zero in case of overflow
-
Input data: Is checked during each I/O cycle for change; if the counter has still not changed
after 10 I/O cycles, then Bit 0 is set to station status and the outputs are switched to failsafe
state (taking into account the Output Delay Time)!
