Hello, I am not very experienced with Siemens PLC's I want to change program in one S7-200 CPU 226 (profibus). I have never connected my laptop to it before and I don't have that PLC's program. I have PC Adapter USB A2 cable for that and V4.0 STEP 7 MicroWIN SP7 program. I connected the cable, opened the program and tried different settings for connection, most of times the test in diagnostics says that status is OK. But! in communications window when ever I try to refresh the adapter is gives me error: "Class not registered" So I'm not able to upload the program from PLC to my laptop. Can anyone give me support?
We recently obtained a new Vendor ID (VID) Number from ODVA, 1477 for the purposes of developing an EtherNet/IP scanner device. When we try to use that number with the Allen-Bradley PLC & Studio 5000 Logix Designer, our data type REAL's are showing up in Studio 5000 as SINT's. We have seen this mangling of data types before when using the Omron VID, 47 with the same Allen-Bradley PLC/EIP Scanner. The data types are being misinterpreted, or mangled from REAL to SINT, e.g. the *.eds file defines 32 REALs for Input and 32 REALs for Output, but within Studio 5000 we see 128 SINTs each for Input and Output. It is as though the Allen-Bradley/Studio 5000 database does not have our Vendor ID. When I change the *.eds file, Vendor ID Number from #1477 to #1 then we see the *.eds file being properly read and interpreted, e.g. 32 REALs for Input and Output show up as 32 REALs each. Does anyone know what file we need to modify in Studio 5000 ??? We want to add our Vendor ID #1477 to that file. Hardware: EIP Scanner: Allen-Bradley Compact Logix L18ERM EIP Adapter: Delta Tau Power PMAC Motion Controller (EIP OpeNer Stack) Thanks in advance! See screenshots below. within Studio 5000, see screenshots
vinny posted a topic in Other PLCsHi I just given a swanky new laptop at work, which is lovely and everything, but does not have an ethernet port. Unfazed by this, I just got hold of a USB to LAN adapter and got to work. My primary development environment is Beckhoff TwinCAT, and was rather gutted to find there are no real-time ethernet devices on the machine(attached image for reference). I was wondering if there was any adapter that I could use for real-time ethernet device. I am aware of latency issues and this would only be used to test communication and make sure everything talk to each other. Cheers
