Version 1.30 from 17.07.09

• V 1.29 ported to Linux, S7-LAN-Link have now the same interface as IP-S7-LINK, but runs only with S7-LAN, so the transition to IP-S7-LINK for the user is a simple
  

Version 1.29 from 20.04.09

• Assembly Interface for .Net Rd method with 32 Bit Integer was reading Bit, now 32 Bit
