Quick Reference Guide Product Definition The adapter is available as: PC adapter 6ES7 972-0CA2x-0XA0 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.
PC/TS Adapter With ’direct connection’, the TS adapter allows you to link programming devices/PCs with S7/M7/C7 systems. With this setup, the TS adapter corresponds in functionality to the PC adapter. With ’modem connection’, the TS adapter enables you to link programming devices/PCs with S7/M7/C7 systems over the telephone network.
Quick Reference Guide Adapter MPI/DP connector RS232 connector Figure 1-3 Adapter The two adapter types differ with respect to the location of the MPI/DP parameters: The MPI/DP parameters for the PC adapter are set in “Set PG/PC interface”. When opening an online display for the first time, ther parameters are transferred to the PC adapter.
PC/TS Adapter Package Components Adapter Quick Reference Guide Mounting assembly (TS adapter only) Accessories (not part of the adapter package) RS232 cable, 6 meters in length 6ES7 901-1BF00-0XA0 (required to operate the PC adapter and to operate the TS adapter in direct connection only). MPI/DP Network A maximum of 32 nodes can be interfaced to an MPI/DP network segment.
Quick Reference Guide Prerequisites for Operation Hardware PC/programming device with a free COM port (COM1 or COM2, 9-pin COM connection). Appropriate adapters for other connector combinations are available in specialist shops, for example 9-pin to 25-pin subminiature D connector. 25-pin subminiature D: Signal: Shield Shield...
Quick Reference Guide General Remarks MPI/DP side: Adapter and S7/M7/C7 system each represent one network node. In networks comprising two nodes (adapter and S7/M7/C7 system), the adapter is plugged directly into the S7/M7/C7 system’s MPI/DP port; in networks consisting of more than two nodes, the adapter is plugged into a Profibus connector’s “PG port”...
PC/TS Adapter As the adapter receives its power supply via the MPI/DP in- terface, only those interfaces can be used which provide 24 V DC and 5 V DC with the voltages and currents specified in the table in the ”Technical Specifications” (Chapter 7). The- refore a connection at the free end of a PROFIBUS cable is not possible.

PC/TS Adapter Function and Operation of the Switch The switch is used for setting the transmission rate (19.2 kbps or 38.4 kbps) on the RS232 side of the adapter variant in direct connection. It has no function with modem connection. The transmission rate set with the switch must agree with the rate parameterized for the PC in “Set PG/PC interface”.
Quick Reference Guide The switch is operated only infrequently and is recessed so that it cannot be operated inadvertently. See Figure 1-11 for the location of the switch. Both switch positions are labeled on the underside of the unit. To operate the switch, please use a ball-point pen (“retractable ball-point”) up to a diameter of 1.7 mm or a blunt instrument of the same size.
