Refreshing time of Variables for Communication propose What is the frequence of updating of Variables available for communication in ATV68 EX: W1030 if configured to be a Speed in RPM?
The ATV68 decides between the PZD communication channel and the PKW.
At the Profibus link both parts have to be transmitted from PLC to the drive. (PPO1- PPO4). Each PZD telegram will be worked out within a 5 ms task. A PKW telegram (read/write a parameter) will be worked out in a 100ms
task. Using the Profibus connection, it will be necessary to send the PKW request as long until you get a response.
By using the Gateways (separated PKW and PZD telegrams)for serial connection the time for the RS232 communication from drive to gateway has to be added.
