Can anyone suggest how to do the wiring for TMPOSINPUT-1 (ET 200SP, TM Posinput 1 6ES7138-6BA01-0BA0) using S7 1200 PLC. We are replacing the Existing S5 High speed counter module 6ES5 385-8MB11 25/500KHZ.instead of this module we are using the TM posinput 1.but in the [snip] wiring part we want to know how to do [snip] . Please suggest how to do. i have the Pin assignment of the existing High speed counter . Pin5- Ground Pin8-Supply voltage (24V) pin13-Rectang-wave signal A(24V) Pin14-Rectang-wave signal B(24V) we have only this information. ------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------ |

Division of questions into separate topics (change from "programming" to "wiring", because the user already has a question about the "programming part"). |

Hello, TM supports only SSI, RS422 or TTL. Please see chapter 3.3 https://support.industry.siemens.com/cs/ww/en/view/109780353 |
With best regards, |

Hello, TMPosInput-1 can't evaluate -Rectang-wave signal A(24V). Check whether your S7-1200 has 24V onboard counter inputs. 10.1 Counting (High-speed counters)....................................................................................... 503 10.1.1 CTRL_HSC_EXT (Control high-speed counter, extended).................................................... 504 https://support.industry.siemens.com/cs/ww/en/view/109814829 10.1 Counting (High-speed counters) The basic counter instructions, described in "Counter operations" (Page 209), are limited to counting events that occur at a rate slower than the scan cycle of the S7-1200 CPU. The Highspeed counter (HSC) function provides the ability to count pulses occurring at a higher rate than the PLC scan cycle. In addition, you can configure the HSC to measure the frequency and period of the occurring pulses, or be setup such that motion control can use the HSC to read a motor encoder signal. To use the HSC function, the HSC must first be enabled and configured using the CPU’s Properties tab in the Device Configuration screen. To get started configuring the HSC, refer to "Configuring a high-speed counter" (Page 517). After you download the hardware configuration, the HSC can count pulses or measure frequency without the need for any instructions to be called. When the HSC is in Count or Period mode, the count value is automatically captured and updated in the process image (I memory) each scan cycle. If the HSC is in Frequency mode, the process image value is the frequency in Hz. In addition to counting and measuring, the HSC can generate hardware interrupt events, operate dependent on the state of physical input points, and produce an output pulse according to a specified counter event. Technology instruction CTRL_HSC_EXT allows the user program to control the HSC programmatically. CTRL_HSC_EXT updates HSC parameters and returns the most up-to-date values when executed. You can use the CTRL_HSC_EXT instruction while the HSC is in Count, Period, or Frequency mode.
