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).

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.
