The 6ES7194-2MN10-0AB0 is a 10-meter shielded PROFINET bus cable with angled M8 plugs at both ends for SIMATIC ET 200AL. The 90° connectors keep the cable parallel to the module face — the right choice when adjacent I/O blocks or wiring duct block the perpendicular exit a straight plug needs.

10 meters vs. 15 meters — how do you choose?

Ten meters covers the majority of in-cabinet and machine-mounted ET 200AL runs. It reaches from one end of a standard 2-meter control cabinet to the other with slack for routing through trunking, or bridges two stations on opposite sides of a machine frame. If the run exceeds 10 meters and a switch in between is not practical, the 15-meter variant (6ES7194-2MN15-0AB0) provides the extra reach. The tradeoff is purely mechanical — longer cable = more routing discipline needed to avoid EMI sources and maintain bend radius. Both share the same shield construction and electrical characteristics.

Green vs. gray — the rule that saves hardware

Green jacket = PROFINET bus, shielded. Gray jacket = 24VDC power, unshielded. The ET 200AL module has a green port and a gray port side by side. Cross-plugging sends 24V into the PROFINET interface and destroys the PHY. The color code is the first line of defense: always match jacket to port color. No exceptions.

Frequently Asked Questions

What is the difference between 6ES7194-2MN10-0AB0 and -0AA0?

The -0AB0 has angled (90°) connectors at both ends. The -0AA0 has straight (180°) connectors at both ends. Both are 10m, green, shielded PROFINET bus cables. Angled wins when clearance is tight; straight wins when the port has open access above it.

Does this cable need separate shield grounding?

No. The shield is terminated inside the molded M8 plug body and connects to the ET 200AL module's functional earth through the connector housing. No external shield clamp or pigtail is needed — the plug-to-socket mating completes the shield path automatically.
