Quick Reference Guide PC/TS Adapter 1 Product Definition The adapter is available as: PC adapter 6ES7 972-0CA2x-0XA0 or TS adapter 6ES7 972-0CA3x-0XA0 Note Where ’adapter’ is referred to below, the text applies to both variants. The PC adapter connects a PC to the MPI/DP interface (Multipoint Interface) via the serial COM port of an S7/M7/C7 system. This does not require a PC slot, that is, the adapter is also suitable for use in non-expandable PCs such as notebooks. 1) 19.2/38.4 kbps PC ada
