Chamo Posted February 16, 2005 Report Posted February 16, 2005 Hi there. I’m new in communication between HMI Siemens and PLC Simatic S7-200. I need to communicate a CPU 226XM with a HMI TP270 and I don’t know how to do this. May anybody help me please?. I need MPI cable pin-out too. Thanks a lot for your help. Regards Chamo PLC Quote
Guest Fritz_frederix Posted February 16, 2005 Report Posted February 16, 2005 Hello, Normaly all S7 PLC communivate with TPxxx on a plug & play manner, so connect your touchpanel with your PLC and it should work( keeping in mind you select the right communication parameters in you TP configuration menu. for the MPI pin-out do a search in this Forum Rudi Quote
Chamo Posted February 16, 2005 Author Report Posted February 16, 2005 Hi Rudi. Well, I try connection using pins 3 and 8 from ports IF1B (TP270) and PORT1 (CPU226). IF1B configuration is OK, but I believe that I have problems with PORT1 configuration and Area Pointers in Protool for TP270. Dou you have any idea about these configurations?. Regards Chamo Quote
