IP address
The IP address is required for identification of the encoder in the EtherNet/IP. This is
obtained for the encoder from a DHCP server (
see "Assigning the IP address via DHCP",
) or permanently entered via address switches (
).
•
If the IP address is obtained via DHCP, then any address range is possible.
•
If the IP address is set via address switches, then the address range is set to
192.168.1.xxx.
3.7.3
Slave sign of life
The absolute encoder supports the slave sign-of-life functionality.
It is transmitted in bit 30 of the Fault header. It is used so that the controller can
determine whether the encoder is in operation even if the position data does not
change (e.g. at a standstill).
The bit changes its value in the configured update cycle.
The update cycle is formed from the requested packed interval (RPI) and an update
factor. The RPI can be between 5 and 750 ms:
Update cycle = RPI × update factor × 6
The update factor is determined with attribute 6Ah of the position sensor object (
The supported value depends on the RPI time of the encoder connection. The update
cycle should be at least twice as long as the RPI (so 1500 ms for RPI = 750 ms).
3.7.4
Code sequence
The code sequence determines at which direction of rotation, starting from a viewing
direction on the shaft, the position value increases.
