5.1.5 Direct key interface
X11 on the operator panel (OP) fronts can be used to fetch the state of the direct keys. The
connection of a 20-pin ribbon cable allows the direct keys to evaluate the following components:
• Direct key module (DTM)
• X70 in the machine control panels (MCP, MPP) and the handwheel connection module (HAM)
• X205 on the Thin Client Unit (TCU)
The signals are then forwarded to the control over the various communications networks.
Note that DTM and HAM can be operated only with PROFIBUS DP.
