Hello,

 

Does anyone use s7plc EPICS support with SIEMENS S7-1200 CPU? I am using CP 1243-1 to establish communication through TCP connection using TSEND_C and TRCV_C instructions.

When I run the IOC I got the following messages:

 

## Register all support components

dbLoadDatabase "dbd/s7-1200.dbd"

s7_1200_registerRecordDeviceDriver pdbbase

#var s7plcDebug 0

s7plcConfigure("s7-1200","192.168.0.2",2000,240,240,1,5000,50)

## Load record instances

dbLoadRecords("db/dio.db")

iocInit

It is shown that IOC is connected but I am not sure if the PLC code configuration in the TIA Portal is correct or not.

Any ideas?

 

Thanks.
