Hi Stefano, Hi Chris,
I tried to pull the latest 0.8.0-SNAPSHOT from the Apache repo (I think I saw
you pushed it there). Thanks for the link to the Wiki page for a local build,
will try this as well later.
I did a quick run with plc4j-driver-s7-0.8.0-20200831.122123-1 (I hope this is
the right one) but it stops at:
16:55:34.460 [nioEventLoopGroup-2-1] DEBUG
org.apache.plc4x.java.spi.GeneratedDriverByteToMessageCodec - Sending bytes to
PLC for message
TPKTPacket[payload=COTPPacketData[parameters=<null>,payload=S7MessageRequest[tpduReference=10,parameter=S7ParameterReadVarRequest[items={S7VarRequestParameterItemAddress[address=S7AddressAny[transportSize=BOOL,numberOfElements=1,dbNumber=20,area=DATA_BLOCKS,byteAddress=5,bitAddress=0]]}],payload=<null>],eot=true,tpduRef=10]]
as data 0300001f02f08a32010000000a000e00000401120a10010001001484000028
Best regards,
Sebastian
