New PLCIO Version 4.3.1 Released

Version 4.3.1 of the PLCIO communications software is now available. This is primarily a bug-fix release for certain issues listed below.

Full Changelog:

  • In the 'enipd' daemon, close CIP connections after 130 seconds of inactivity in order to prevent stale TCP connections from building up.
  • Apply fixes to daemon/plciod.c so that it will compile on HP-UX's native C compiler.
  • Add multipart-PCCC tracking to the 'abeth' and 'enip' modules, so that they can correctly interpret PLC5 multipart PCCC messages interleaved with other single or multipart messages during a plc_receive(). (Multipart messages are all PLC5 Typed Writes greater than 240 bytes in length.)
