Entitlements and Expansion Rules for PCS 7 Engineering Bundle 6ES7651-5AA58-0YA0

The SIMATIC PCS 7 V9.0 Engineering bundle order number 6ES7651-5AA58-0YA0 (PCS 7 ES Single Station V9.0) includes an Unlimited AS/OS Engineering license (enabling engineering of unlimited Process Objects on the ES), bundled with a baseline runtime entitlement of 250 AS Runtime Process Objects (AS RT PO) and 250 OS Single Station Runtime Process Objects (OS RT PO). The runtime capacity can be expanded modularly: AS RT POs are increased using expansion packages like 6ES7653-2BA00-0XB5 (100 POs) or 6ES7653-2BB00-0XB5 (1000 POs), and OS RT POs are increased using packages like 6ES7658-2XA00-0XB0 (100 POs) or 6ES7658-2XB00-0XB0 (1000 POs).

Architecture and Scope of the ES Single Station Package

In SIMATIC PCS 7, small-to-medium process plants and pilot installations frequently deploy a combined Engineering System and Operator Station on a single computer (ES/OS Single Station). To streamline procurement, Siemens provides the consolidated bundle package PCS 7 Engineering Software and OS Software Single Station V9.0 under order number 6ES7651-5AA58-0YA0.

This package delivers both the engineering toolset required to program the controllers and design the HMI, and the runtime software required to operate the plant from the same workstation. Understanding the distinction between Engineering POs (which are unlimited) and Runtime POs (which are strictly counted and capped at 250 POs out of the box) is essential for compliant project sizing.

Entitlement Breakdown of 6ES7651-5AA58-0YA0

Purchasing 6ES7651-5AA58-0YA0 supplies the following explicit license keys delivered via USB hardware stick or OSD:

PCS 7 Engineering (Unlimited POs): Authorizes SIMATIC Manager, CFC, SFC, SCL, NetPro, and OS Project Editor for unlimited engineering without Process Object restriction.
AS Runtime Process Objects (250 AS RT PO): Authorizes the execution of up to 250 technological blocks (motors, valves, controllers) loaded into the automation stations.
OS Single Station Runtime (250 OS RT PO): Authorizes WinCC Runtime to operate with up to 250 process objects representing dynamic visual faceplates and archived measuring points.
WinCC Basic Software: Integrated WinCC Single Station runtime environment including Alarm Logging and Tag Logging.

Commercial Accuracy Guardrail: Software order numbers (MLFBs), Process Object counting rules, and expansion compatibility must be verified against current Siemens Catalog ST PCS 7. Final quotations should be validated through an authorized Siemens distributor.

Step-by-Step License Transfer and Capacity Verification

To install, expand, and audit Process Object licenses in Automation License Manager:

Transfer Base Licenses:
- Insert the USB License Stick containing 6ES7651-5AA58-0YA0 into the Engineering Station.
- Launch Automation License Manager (ALM).
- Drag the PCS 7 Engineering V9.0, AS RT PO (250), and OS Single Station RT (250) licenses to drive C:.
Apply PO Expansion Packages:
- Connect the expansion license sticks (6ES7653-2BA00-0XB5 or 6ES7658-2XA00-0XB0).
- Transfer the expansion license keys to drive C:.
- In ALM, confirm that cumulative total counts reflect base plus expansion quantities.
Audit AS Process Object Utilization in SIMATIC Manager:
- In SIMATIC Manager, select the target S7 Program under your CPU.
- Select PLC -> Process Objects -> Display Process Objects.
- The utility queries all CFC charts and displays: Total licensed AS POs, consumed AS POs, and remaining balance.
Audit OS Process Object Utilization in WinCC:
- In WinCC Explorer, verify the status bar external tag counter or run the OS compilation summary to confirm OS RT PO bookings match licensed ALM totals.

Verification

Verify functional licensing:
1. Open Automation License Manager and verify all license keys display a green checkmark indicating validity.
2. Perform a test CFC compilation and verify that compilation completes without Process Object deficit errors.
3. Start WinCC Runtime on the single station and confirm that runtime remains active past the 1-hour demo timeout without licensing alert dialogs.
4. Check the Windows Application Event Log to ensure zero ALM license deficit warnings are logged.

Limitations and Operational Precautions

Single Station vs Server Distinction: 6ES7651-5AA58-0YA0 is exclusively an OS Single Station license. It cannot be used to operate an OS Server serving remote OS Clients without purchasing a Single Station to Server Upgrade package.
Separate AS and OS Accounting: AS RT POs and OS RT POs are independent entitlements. Expanding AS RT POs by 500 does NOT expand OS RT POs; both must be expanded to match the plant's technological scale.
License Upgrades: Upgrading from older releases (e.g., V8.2 to V9.0) requires upgrade packages (6ES7651-5AA58-...) rather than new full packages.

Engineer FAQ

Does 6ES7651-5AA58-0YA0 allow engineering of more than 250 Process Objects?

Yes. The engineering license allows engineering an unlimited number of Process Objects in SIMATIC Manager. The 250 PO limit applies strictly to the runtime execution on the AS controller and WinCC OS.

Can I use 6ES7653-2BA00-0XB5 to expand WinCC OS tags?

No. 6ES7653-2BA00-0XB5 is strictly an AS Runtime PO expansion license. To expand WinCC OS Runtime POs, you must use 6ES7658-2XA00-0XB0 (100 OS PO) or 6ES7658-2XB00-0XB0 (1000 OS PO).

What happens if my AS controller program consumes 300 POs while only 250 are licensed?

The CFC compiler will issue a license shortfall warning. In CPU 410-5H controllers, a Process Object deficit will eventually prevent subsequent changes-only downloads or flag a license violation in CPU diagnostic buffers.

Can an ES Single Station be upgraded to an OS Server later?

Yes. Siemens offers the 'Single Station to Server Upgrade' package to convert the OS Single Station license into an OS Server license capable of serving multiple OS Clients.
