Version 1.25.11 - 2020.7.7

• Bugs fixed
• An other bugfix in the INAT configuration impoet fixes another IEEE import issue.
• The timeout in writing the station parameters to a device is longer now. This should prevent the timeout message after the parameter download was completed.
• On the Regor devices now DCHP can be configured on the second network adapter without any error message.

Version 1.25.10 - 2020.6.15

• In Siemens S7 1500 connections in instance data blocks now the TIA standard view can be changed for compatibility with some S7 1500 toolkits. The "static" elements will be dropped if it is the only element containing PLC variables.
• Bugs fixed
• In the INAT import in Siemens S7 symbols now the conversion from IEEE is working correctly

Version 1.25.9 - 2020.6.8

• Siemens S7 300/400 bit write has a new option vor very old PLC models: Do not use the native bit write, use as alternative: Read byte, modify bits, write byte. This is unsave. If the PLC program and the OPC Server are writing in the same element a data loss will be happen.

Version 1.25.8 - 2020.5.22

• Bugs fixed
• Siemens S7 1500 with firmware 2.8 now allows writing big arrays also.

After many hours running the PLC access to some models are breaking the connection for a very short time. The new setting now allows ignoring this interruption, so the OPC client does not see any warning.

• Modbus reading inputs now correctly reads input registers.
• Modbus now handles arrays in the input and output area.
• OSI(H1 now establishes the connections stable also if many connections will be started in a short time.
• In the OPC DA client a stability issue is fixed. This did happen when an OPC Server doesnt return the data type at the function ValidateItems(). With other words a workaround for more compatibility for not compatible OPC Servers.
• The OPC toolkit c# returns correct values for the values in structures.

Version 1.25.5 - 2020.4.6
