The 6ES7194-2MH03-0AB0 is the shortest angled PROFINET bus cable for ET 200AL—0.3 meters long with angled M8 plugs at both ends and a green PUR jacket. It daisy-chains bus communication between tightly spaced modules while keeping the cable profile flat to the mounting surface.

When do you need 0.3 meters instead of 1 meter for bus?

Within a single enclosure, adjacent ET 200AL modules are 50–150mm apart. A 0.3m bus cable links them directly—no excess to coil, no loop to secure, no slack to snag during maintenance. In a high-density I/O station, eight 0.3m bus links produce a visibly cleaner panel than eight folded 1m cables. The 1m variant (6ES7194-2MH10-0AA0 or 0AB0) is the right tool when modules sit in separate enclosure sections.

Why angled connectors on a 0.3m bus link?

Angled connectors route the cable parallel to the module face rather than perpendicular to it. At 300mm, the cable is too short to loop away from the enclosure door even if you wanted to—the angled orientation ensures the cable runs flat along the mounting plate from the moment it leaves the port. This also eliminates the risk of a straight connector snagging on a closing door or a technician's sleeve during commissioning.

Frequently Asked Questions

Is the green bus cable compatible with third-party PROFINET devices?

The M8 connector and PROFINET protocol are standard. However, third-party devices may use a different pinout or port gender—verify the target device's M8 bus port specification before connecting. Within the ET 200AL ecosystem, all M8 bus ports follow the same pinout.

What is the difference between this and the 0AA0 (straight) variant?

The 6ES7194-2MH03-0AA0 has straight M8 plugs—same 0.3m length, same green shielded construction, but with connectors that project perpendicular to the module face. Choose 0AB0 (angled) when door clearance or machine routing demands a low profile; choose 0AA0 (straight) when clearance is adequate and ease of handling is the priority.
