Check IM 155-6PN HF Compatibility Before Replacing an ET 200SP Interface Module
Do not assume 6ES7155-6AU00-0CN0 and 6ES7155-6AU01-0CN0 are interchangeable in PCS 7 V9.0 SP3. A reported system produced hardware errors when AU00 was configured but AU01 installed; matching the AU01 GSDML reportedly cleared them, while PCS 7 channel-driver blocks remained unavailable. This report does not establish release status or a universal workaround.

Reported configuration
The source describes PCS 7 V9.0 SP3 with interface modules 6ES7155-6AU00-0CN0 and 6ES7155-6AU01-0CN0. AU00 configured/AU01 installed reportedly raised hardware errors; matching AU01 GSDML reportedly cleared them, but without channel-driver blocks.
Compatibility checks
A matching device description may address identification mismatch, but does not prove release status, driver generation, alarms or Maintenance Station integration. Confirm exact firmware, GSDML, PCS 7 update, controller and required diagnostics against Siemens compatibility data.
Test and acceptance
Test hardware diagnostics, PROFINET communication, module/channel quality and required PCS 7 drivers in the exact configuration. A clean compile or disappearance of one message is not full acceptance.
Verification
Confirm configured order number matches the physical module, inspect diagnostics, then verify runtime I/O and every required channel-driver and maintenance function.
Limitations and Operational Precautions
The source had no test system or exact error text. Siemens compatibility lookup was inaccessible. The device catalog below is not proof of PCS 7 V9.0 SP3 driver support; do not call this workaround universal.
Engineer FAQ
Does matching AU01 GSDML prove support? No. It is a case-specific report; verify release status and PCS 7 driver functions separately.
