Siemens 6ED1055-4MH00-0BA0 LOGO! TD four-line text display

Siemens 6ED1055-4MH00-0BA0 is documented for the stated industrial system role: Displays LOGO! status and message text and accepts the operator's local key input through the connected TD interface.

System function

Rebuilt from individual evidence

System position

The exact-reference data sheet identifies 6ED1055-4MH00-0BA0 as the LOGO! TD text display for LOGO! 0BA6/0BA7 with four text lines and a 2.5 m cable.

The distributor record identifies the Siemens module as an operator console with 12 V DC supply and IP65 rating.

Displays LOGO! status and message text and accepts the operator's local key input through the connected TD interface.

The system position is an explicit inference from the exact-reference evidence.

Unknown: loaded message project, base-module revision, cable condition, panel installation, and current commercial availability.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Displays LOGO! status and message text and accepts the operator's local key input through the connected TD interface.
System position: Sits at the operator-facing boundary beside a LOGO! 0BA6/0BA7 base module.
Upstream / inputs: Receives display data and power through the documented TD cable connection.
Downstream / outputs: Presents four lines of text and forwards local key actions to the LOGO! base module.
Limitations: Unknown: loaded message project, base-module revision, cable condition, panel installation, and current commercial availability.

Inferences

Inferred system position: Sits at the operator-facing boundary beside a LOGO! 0BA6/0BA7 base module.
Confidence: medium
Rationale: The exact-reference sources establish the product identity and documented interfaces; their relationship to the stated upstream and downstream elements is marked as an inference.
