Product details

That range covers platform topsides, arctic-term pipelines, and desert-process skids without requiring additional climate control. It shares the standard 130 mm × 100 mm × 75 mm footprint, so it drops into a standard S7-1200 panel without rewiring.

Compared to the later-order-code peer 6AG1215-1AG40-4XB0, this -AG31-2XB0 shares the same temperature rating and communication hardware. The difference lies in firmware version and possibly fieldbus software options. If your application does not require the latest firmware feature set (e.g., extended security functions), this unit is a direct drop-in replacement.

Frequently asked questions

What programming languages does 6AG1215-1AG31-2XB0 support?

It supports FBD, LAD, and SCL as listed in the specification.

What is the operating temperature range?

The CPU operates from -40 °C to +70 °C ambient.

Does it have PROFINET and MODBUS?

Yes, PROFINET (as client and server) and MODBUS TCP/UDP are included.

How much memory does it have?

It has 4 Mbyte integrated work memory.

Can I replace 6AG1215-1AG40-4XB0 with this unit?

The -AG31-2XB0 and -AG40-4XB0 share the same form factor, temperature range, and communication interfaces. The -AG40-4XB0 is a later firmware revision; confirm your application software compatibility before swapping.
