Product details

I/O and communication handling

The 6ES7211-1AE31-0XB0: I/O address space is 1 024 byte each for inputs and outputs. Onboard communication includes TCP/IP, MODBUS (client and server), PROFIBUS, and AS-Interface. Forcing and watching variables is supported over variables covering inputs, outputs, memory bits, DBs, distributed I/Os, timers, and counters.

Environmental and approvals

Backup time is 480 h (typical) for the real-time clock, enough to survive a long weekend power loss without recalibration. Approvals pile up: cULus, CE, FM, UL, CSA — all present, which keeps integration straightforward for North American and European machine builders.

Frequently asked questions

What programming languages does this CPU support?

The 6ES7211-1AE31-0XB0 supports FBD (function block diagram), LAD (ladder logic), and SCL (structured control language).

What communication protocols are built in?

It includes TCP/IP, MODBUS (client and server), PROFIBUS, and AS-Interface. The PROFINET interface supports autocrossing.

Does this CPU have safety certification?

It is not PROFIsafe enabled (PROFIsafe: No). For safety applications, you need a separate F-CPU or safety module.

What approvals does this CPU carry?

It has cULus, CE, FM, UL, and CSA approvals, covering most global machinery markets.
