Hello Can you help me,

S7 1200 plc et200 module connected. But et200 module don't use to counter. ( ET 200S, 1 COUNT 24V/100KHZ )

First, check your datasheet on the encoder.  You mention TTL (implied +5V), but the counter card is +24V (HTL).  Make sure it is compatible or you will destroy the encoder.

In my limited experience with SEW encoders, I don't remember a +UB, only a UB, so check its function also. 

To connect to the counter card, you will only be using the A, B and Power supply, so

A --> Terminal 5
B --> Terminal 1
UB --> Terminal 6 (+24V)
0V --> Terminal 7 (0V)

Ground your shield to PE close to the counter card.

The rest of the wires are not used.  Keep in mind also that your cable length should be less than 15m.

New question published by candemirhalil is split to a separate thread with the subject S7-1200 and ET200: How to make the wire connecting diagram ? .

Hello,

one logical tip, pls take to account from where you selected that instruction/block for HSC operation. I expect from S7-1200 library, correct? But you don't control HSC on S7-1200 but on external S7-300/400 distribution system and via PN channel so I want only point to this.
