- repeated errors on poller are only once logged (per poll function / read_* method) - during exception handling, silent=True on a SECoP error indicates that the error is already logged + fix the name of HardwareError + add test for consistency of SECoPErrors + catch socket.timeout in AsynTcp Change-Id: I9df6c775cc19553b22a4d6e39591092adf7ff9a1 Reviewed-on: https://forge.frm2.tum.de/review/c/sine2020/secop/playground/+/28139 Tested-by: Jenkins Automated Tests <pedersen+jenkins@frm2.tum.de> Reviewed-by: Markus Zolliker <markus.zolliker@psi.ch> Reviewed-by: Enrico Faulhaber <enrico.faulhaber@frm2.tum.de>
