Product details

The 6AG1211-1AE31-4XB0: Programming is supported in FBD, LAD, and SCL. The onboard PROFINET interface handles MODBUS TCP, UDP, and AS-Interface, and it can function as both client and server.

Confirm your enclosure’s ambient extremes before specifying. Backup time of 480 h typical lets the CPU retain program and data memory for up to 20 days without power. For longer interruptions, consider a UPS or external memory card. Supply voltage is 24 V DC with a permissible range of 20.4 V to 28.8 V. The CPU draws its power from a standard 24 V bus; a separate load supply is not required for the module itself.

Frequently asked questions

What programming languages does this CPU support?

FBD, LAD, and SCL are all supported, per the evidence.

What communication interfaces are built in?

PROFINET with MODBUS TCP/IP and UDP, plus AS-Interface and PROFIBUS, with client and server capability.
