ACS 800 RETA-02 comms - PPO 4
Hi all!
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:
51.18 1202
51.19 1203
51.20 1204
51.21 1205
Input parameters:
51.22 106
51.23 104
51.24 105
51.25 320
And 51.26 1
Am I missing something, or doing something wrong?
Cheers!

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.
Module Status:
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.
