P714 (CB parameter 4)
P699 (CB parameter 4)
Number of process data to be sent in the case of PZD-send
With this parameter, the number of process data to be sent in the case of
PZD-send is specified. Valid values are 1 to 16 words. From this information,
the actual number and the length of the CAN data telegrams are determined.
If the number of process data is outside the valid range (1 to 16), error F080
appears when status 4 "hardware configuration" is left. After
acknowledgement of the error, you are in the "hardware configuration" status
again and can correct the incorrect parameterization.
Example:
The basic identifier for PZD-send in P713 / P698 is set to 200. The node
address in P918 is 50. This results in a CAN identifier of 200 + 50*4 = 400 for
the first CAN data telegram of PZD-send. If the number of process data (P714
/ P699) is now 10, a CAN data telegram with four words with CAN identifier
400 and a telegram with CAN identifier 401 is sent as is a CAN data telegram
with two words and CAN identifier 402. These are the entered 10 words of
process data. CAN identifier 403 is unused and is not sent.
P715 (CB parameter 5)
P700 (CB parameter 5)
Up-date rate for PZD-send
With this parameter, the up-date rate is set in milliseconds for PZD-send, i.e.
the time base in which new actual values are to be sent from the unit.
Meaning of the parameter values:
•
0:
Actual values are only sent on request (remote transmission
requests).
•
1 to 65534: Actual values are sent according to the time set in ms or on
request (Remote Transmission Requests).
65535: Actual values are sent if the values have changed (event) or on
request (remote transmission requests). This function should only be
used if the values to be transferred only rarely change because,
otherwise, the bus load becomes very high.
