Version 1.20.15 - 2020.7.30

• Internal test version

Version 1.20.12 - 2020.7.7

• Bugs fixed
• An other bugfix in the INAT configuration impoet fixes another IEEE import issue.

Version 1.20.11 - 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.

• In the INAT import in Siemens S7 symbols now the conversion from IEEE is working correctly.

Version 1.20.10 - 2020.6.3

• Bugs fixed
• In the locic table input element a issue is fixed. Now the value is correctly also if sync read is used. Older versions sometimes did deliber wrong values if the variable consists from multiple bytes.

Version 1.20.9 - 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 1.20.8 - 2020.5.22

• PLC Engine Collect Minimum De Luxe and PLC Engine Collect Minimum Database De Luxe added.
• Bugs fixed
• Siemens S7 1500 with firmware 2.8 now allows writing big arrays also.

• Bugs fixed
• In Rockwell PLC access a rarely happen timing effect ist fixes. If did happen if mang global variables are extsing and the first access in startup is a PLC write.
• A rarely occurring effect in conjunction with Siemens S7 1500 models has a special configuration. 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.
• Writing of complete structures containing boolean values now will work with Siemens firmware 2.8.

• The OPC toolkit c# returns correct values for the values in structures.

Version 1.20.5 - 2020.4.6
