Remedied from?
Communication module Profibus E94AYCPM FW 1.05
Eliminated function restriction?
The communication module the DP-V1 communication can be executed without deceleration.
Which products are affected?
Communication module Profibus E94AYCPM FW 1.00
What happens?
The DP-V1 communication (acyclic parameter channel) fails during communication.
When does the problem occur?
If a DP-V1 response from the communication module is followed too quickly by a new DP-V1 request sent to the communication module.
Possible diagnostics?
A DP-V1 request is not answered anymore by the communication module.
Short-term measures/recommendations?
Decelerate the DP-V1 communication on the PLC side.
Evaluation
Since it is a parameter communication, no critical states may occur.
