PLC S7-200 SMART To HMI Pro-face Communication


PLC S7-200 SMART to HMI Pro-face Communication. In this post, 365electricalvn shows you: ” How to Connect Siemens PLC S7-200 SMART And HMI Pro-face Use RS485 Port” Use GP-Pro EX 4.09 and Step 7 MicroWIN SMART 2.6 Programming Software.

Communication S7-200 SMART PLC to HMI Pro-face

On GP-Pro EX programming software, we do not see the S7-200 SMART PLC in the device support list. We used the S7-200 PLC in the device support list to connect Proface HMI to PLC S7-200 SMART. And it is successful, we can monitor and control the PLC from HMI via RS485 Port.

To communicate Pro-face HMI to PLC S7-200 SMART we used:

  • S7-200 SMART to HMI Pro-face – Hardware:
    • Siemens S7-200 SMART PLC CPU ST20.
    • Pro-face HMI GP 4402WW
    • COM 9 pins (Male and Female) for communication cable.

  • PLC S7-200 SMART to HMI Pro-face – Software:
    • Step7 Micro/WIN SMART latest version for S7 200 SMART PLC programming.
    • GP-Pro EX 4.09 SP1 for Pro-face HMI programming.

Connection S7-200 SMART To HMI Pro-face On The Software

On Siemens S7 200 SMART PLC Software

  • Open Step 7 Micro/WIN SMART and create the project with the device.
  • Set the parameter for RS485 port: Address and Baud rate

On Proface HMI Software

  • Open GP-Pro EX and create the project with the device.
  • On the “Device/PLC” step, select:
    • Manufacturer: Siemens AG
    • Series: SIMATIC S7 MPI Direct
    • Port: Select the RS485 port (COM 2)
  • add-device-on-gp-pro-exClick “New Screen” and then click on “Project” -> “System Settings” -> “Device/PLC”. Set the parameter:
    • Speed: Same as the baud rate on PLC.
    • Device-specific settings set PLC Type: S7-200; Target node: PLC address.
    • Tick on “Use Tag Data” and add the tag to the list with the address from PLC.
  • Create the HMI object with the address from the tag list above. 
  • Check the error and download the project to HMI.  You can download the program via Ethernet, or a USB flash drive. Refer to the previous post for more information.  

Communication Cable Proface HMI To PLC S7 200 SMART

  •  You can buy the “MPI cable (3.5m) by Pro-face” to connect Pro-face HMI and PLC S7 200 SMART.
  • mpi-cable-use-gp-pro-exOr make the cable for connect S7-200 SMART to HMI Pro-face following the below diagram
  • pro-face-hmi-connect-s7-200-smart-diagramFinally, turn on the power and check the communication Proface HMI to PLC S7 200 SMART by try change some values on HMI and check on PLC or vice versa.
