I am facing problem to communicate My PC with PLC S7-200. I have STEP 7-MicroWIN V4 SP3 software on my computer and PPI multimaster cable to connect with PLC. PLC-7-200 and HMI S7 TD200 are connected in my system. Uploading the blocks are successfuly completed but force in ,force out, Edit the ladder and all other on line facilities are not accessable. Moreover I am unable to see any indication from where I can ensure that I am online. Sorry for these basic questions. Actualy I have worked on Allen bradely PLC-3 and SLC-500. I have no idea about seimens PLC.
