ACS 800 RETA-02 comms - PPO 4
I've got an ACS800 drive communicating over profinet (RETA-02) to a Siemens S7-1200 PLC. I've got no problems using PPO3, but need PPO4 at least and when I select this, it makes the module status led flash red.
I've configured all the I/O from the Drive (51.18 - 51.26), and matched 51.26 in my PLC configuration for the PPO4.
I don't use constant speeds, and don't need to write anything extra in the drive, but I was told I still need to enter something there. My out parameters are:
And 51.26 1
Am I missing something, or doing something wrong?

Hi, few month ago I had the same task: S7-1215 and ACS800-04 (RETA-02).
I used PPO6 and didn't have any problems.
Which pattern of flashing red light do you have?
The description of the LEDs in PROFINET IO is presented below.
Flashing red (pattern 1) - Configuration error;
Flashing red (pattern 2) - No IP address;
Flashing red (pattern 3) - No station name;
Flashing red (pattern 4) - Failed to initialize the module;
Flashing red (pattern 5) - Temporary host communication lost.
