More Information

Overview Manuals Panel Operation DP & MPI Rack Expansion Engineering

Features:

  • CPU 315-2DP control and OP17 operation share one panel-mounted station.
  • MPI and PROFIBUS DP support engineering, operator, and distributed-I/O communication.
  • An integrated IM 360 extends the S7-300 side across multiple rack rows.
Siemens 6ES7634-2BF02-0AE3 places control execution, local text operation, and distributed communication inside the C7-634 DP assembly.

The OP17 portion of 6ES7634-2BF02-0AE3 presents messages, process values, and recipes that are tied to the integrated CPU project.

STEP 7, ProTool, rack expansion, and panel sealing must be coordinated when installing or restoring 6ES7634-2BF02-0AE3.

The Siemens 6ES7634-2BF02-0AE3 C7-634 DP Compact Station may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6ES7634-2BF02-0AE3 SIMATIC C7-634 DP Compact Station Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Integrated OP17 Resources

  • Text display: The backlit LCD presents eight lines with up to forty characters per line for process and message views.
  • Key operation: Sixteen function keys and eight softkeys send the configured operator commands to the station project.
  • Message handling: Operating and fault-message buffers retain entries so the operator can review current and recorded events.
  • Recipe storage: The 20 KB recipe area groups process parameters that are transferred between the operator project and controller.

Two Communication Roles

  • MPI path: MPI connects programming devices, PCs, operator stations, and S7 partners at up to 187.5 kbit/s.
  • DP master: The second interface can control distributed PROFIBUS DP slaves at rates up to 12 Mbit/s.
  • DP slave: The same interface can instead present the compact station as a configured DP slave to another master.
  • Address capacity: A DP station can exchange up to 122 bytes while the master configuration supports as many as 64 slaves.

Local S7-300 Extension

  • Integrated coupling: IM 360 provides the expansion path from the compact station to additional S7-300 rack rows.
  • Row limit: The documented arrangement extends across a maximum of three rows.
  • Module capacity: Up to 24 expansion modules can be assigned within the supported rack and address resources.
  • Resource planning: Analog, digital, function, and communication modules consume different I/O addresses and recommended processor resources.

Controller and HMI Project Coordination

  • CPU project: STEP 7 defines the controller program, hardware arrangement, addresses, and communication relationships.
  • Operator project: ProTool assigns screens, messages, keys, passwords, recipes, and process-variable links to the OP17 portion.
  • Shared tags: The operator variables must reference addresses and data structures that exist in the loaded CPU project.
  • Panel boundary: The IP65 front rating applies at the installed panel face, while the IP20 rear requires enclosure protection.
Description
Siemens 6ES7634-2BF02-0AE3 is the SIMATIC C7-634 DP compact control station that unites an S7-300 CPU 315-2 DP, a SIMATIC OP17 operator interface, an IM360 expansion connection and a PROFIBUS DP master. It executes the machine program, presents operator data and coordinates distributed I/O from one enclosure.

Inside 6ES7634-2BF02-0AE3, the CPU uses work memory for active logic while FEPROM or RAM load memory holds program blocks and project data. The operator section reads controller variables for its display and returns key entries to the logic, so the STEP 7 and ProTool projects must describe the same tag relationships.

The integrated DP master of 6ES7634-2BF02-0AE3 exchanges process data with assigned PROFIBUS slaves at the configured bus rate. MPI provides the engineering and controller communication path, while the IM360 interface extends the local S7-300 I/O arrangement into the permitted expansion racks.

Panel mounting places the IP65 face of 6ES7634-2BF02-0AE3 at the operator side and leaves its IP20 electronics within the enclosure. The 24 V DC supply powers the combined station, so cabinet wiring must account for the CPU, display and communication sections as one product rather than as separate modules.

Technical notes
Siemens 6ES7634-2BF02-0AE3 combines the CPU 315-2 DP, OP17 and IM360 functions in one C7-634 DP housing. Confirm the saved STEP 7 and ProTool projects together because controller logic and operator-screen configuration belong to different integrated sections.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can the OP17 display of 6ES7634-2BF02-0AE3 show values while a key command has no effect?
For 6ES7634-2BF02-0AE3, compare the ProTool key assignment with the CPU address, password level, operating mode, and loaded STEP 7 data structure.
What should be checked when 6ES7634-2BF02-0AE3 cannot reach a PROFIBUS DP slave?
Verify the 6ES7634-2BF02-0AE3 DP-master role, station address, transmission rate, slave configuration, cable continuity, shield bonding, and both segment terminations.
Can 6ES7634-2BF02-0AE3 be configured as a PROFIBUS DP slave instead of a master?
Yes. The second interface of 6ES7634-2BF02-0AE3 supports either DP-master or DP-slave operation, but the STEP 7 hardware configuration must match the selected role.
Why must both STEP 7 and ProTool files be retained for 6ES7634-2BF02-0AE3?
The 6ES7634-2BF02-0AE3 CPU logic and hardware configuration reside in STEP 7, while OP17 screens, messages, keys, and recipes are defined in ProTool.
How is the IP65 protection of 6ES7634-2BF02-0AE3 maintained?
Siemens 6ES7634-2BF02-0AE3 provides IP65 at the front only when installed with the specified panel cutout and sealing; the rear remains IP20.
