C6015 C memory running low - low performance

[JohnnyNx]

Hello everyone,
we use a C6015 to implement a second control panel with HMI on the back of the machine. The connection is then established via a route to the main controller (VPB40.4). The problem is that the C6015 reacts extremely slowly after a certain time and the memory on C is getting less and less. The Nexeed Master Image V3.31 with the TwinCat version 4022.30 is used on both controllers. The image has already been reloaded on the C6015. Nevertheless, the problem persists. How to solve this problem?

Hello,

try following:

1. Remove unnecessary addons from HMI for C6015. This PLC has not enough power to run all addons.
2. Disable start of TwinCAT runtime if you do not need it. If I understand correctly you do not need to run PLC on the C6015.
3. Open OpconSystemStartup.bat at the target system and suppress execution of unnecessary runtimes.
4. I also remember DataSetAcces was source of memory issues in some cases. The solution was cleanup of OpconApp\DataSetAccess\Config folder at the target.
