Example: Changing a subscription
61161
Task:
The existing subscription (
Example: Subscribing to notifications
(
)) is to be changed.
Instead of the temperature of the IO-Link master, the operating voltage applied is to be transmitted.
Solution:
Overwrite the existing subscription. For this purpose, the parameter values for "cid" and
"callback" in the request must be the same as those of the existing subscription.
