Dear Sir,
I havePCADAPTERUSB (6ES7 972-0CB20-0XA0) and CPU 224 (6ES7 214-1AD23-OXBO) S7 200.The problem is the same before.I try to doyour advise to configure in control panelPG inerface set toPCADAPTERPPI, but the problem is stillthere.I read some of your manual aboutMPI cable isaround 0.3 meters for technical reason and, i will use comercial cable RS232 9pin around 1.5 meters.I buy in computer shop.My original MPI cable together with the PC ADAPTER USB is damaged already. So i try to use a comercial cable RS232 9pin.In S7 300 Simatic manager, its working. Only in S7 200 Microwin V4.0 service pack 8 is not working.Posible the CPU224 is the problem or the MPI cable?I hope to hear you regarding this matterThanks and best regards to your helpful forum.
