I have found a solution for my problem. So, if RCV_PTP returns an OK code (16#0099) but zero LENGTH, I use these conditions to iterate loop call to RCV_PTP until it returns OK code and non-zero LENGTH. It works with only one iteration after zero LENGTH. See the explanation of this behavior in the next post! |

After thorough researching, I have found the answer for my problem. It is described in documentation (System Manual, V4.4 11/2019) on page 1194: When the EN_R input is TRUE and a message is available, the CPU transfers the message
So, I did not enabled EN_R and it was the reason the LENGTH was 0. |
