16#005F 
A nonexistent file is read from the 
memory card, or a nonexistent file 
is written to the memory card. 
Check whether the file path is correct. 
16#0060 
The CPU module can not create a

1. Check the actual network configuration, and check 
whether the number of TCP connections exceeds the 
upper limit supported by the CPU module. 
2. Retry the TCP connection later. (This error does not 
cause the PLC to stop running. Users can perform the 
corresponding remedy by means of the related flag in
