Hi there, I am using LMqtt library from (https://support.industry.siemens.com/cs/ww/en/view/109748872 ). I was able to perform publishing at a rather good rate of 40-60 messages per second on unencrypted channel. However, upon activation of secure channel, the CPU crashes after 3-4 messages sent out with the following error of sort:
The CPU recovers after power cycle but will crash again after 3-4 encrypted messages. I am wondering if any one else has encountered a similar problem before? CPU details as follow: CPU: 6ES7 214-1AG40-0XB0

The encrypted MQTT library is only available for the s7-1500 (means it only works with the s7-1500). |
