Hi,

 

For asyn based Siemens PLC driver development, currently I am using IP Port driver with below configuration and primary development is working good with block data transfer.

 

drvAsynIPPortConfigure("PLC_SAMPLE_CPU_2000", "10.130.1.109:2000", 0, 0, 1)

drvS7synConfigure("P0_cfg", "PLC_SAMPLE_CPU_2000", 128, 66, 50, "PLCSample 0")

 

Now to handle the redundant PLC configuration, I have to connect to two PLCs, and I will process/pass the data from any one plc out of two, so I am thinking like, to open two connection using IPPort driver and use them both in my driver like below,

 

drvAsynIPPortConfigure("PLC_SAMPLE_CPU0_2000", "10.130.1.109:2000", 0, 0, 1)

drvAsynIPPortConfigure("PLC_SAMPLE_CPU1_2000", "10.130.1.110:2000", 0, 0, 1)

 

drvS7synConfigure("P0_cfg","PLC_SAMPLE_CPU0_2000", "PLC_SAMPLE_CPU1_2000", 128, 66, 50, "PLCSample 0")

 

In this case  I will have problem with registering the port and interfaces for my driver. So will above method will work ? or please suggest the good way to tackle this problem.

 

Thanks and best regards,

Jignesh
