I am using the ABTCP3/SSTAB drivers and it reports 'Error 0x10100'. What could be the reason? 

'Error 0x10100' means the PLC is out of buffer space. The buffers are used in communications between Citect and the PLC. There are a number of reasons why it may run out of buffers:
  1. There may be multiple computers (using Citect, programming software, another SCADA package etc.) that may be trying to communicate to the PLC. The PLC may not be able to handle this many clients requesting data.
  2. The buffers may not be released after the last request by Citect before Citect requests again. The overcome this try the CITECT.INI parameter [ABTCP]Delay=10 then 20, 40 etc.
