Handwheel interfaces at the Ethernet Bus
The handwheel interfaces at the Ethernet bus are numbered on the basis of the following
considerations:
● The sequence of the operator component interfaces is: MCP1, MCP2, BHG
● Each operator component interface has two handwheel interfaces
● Operator components: MCP 483C IE
A maximum of two handwheels can be connected to an MCP 483C IE via connections
X60 and X61 . The assignment of the connections in the operator component interface is:
– Connection X60: 1st handwheel in operator component interface MCP1 /MCP2
– Connection X61: 2nd handwheel in operator component interface MCP1 /MCP2
● Operator components: HT 8
The handwheel of the HT 8 is always assigned to the 1st handwheel of operator component
interface MCP1 /MCP2 .
● Operator components: HT 2
The handwheel of the HT 2 is always assigned to the 1st handwheel of operator component
interface BHG .

Handwheel interface at the Ethernet bus (y)
1) Numbering of the handwheel interfaces within an operator component interface
2) Assignment of the operator component to the interface via the corresponding FB1 parameter
3) Assignment of the handwheels of the respective operator components to the handwheel interfaces
4) Numbering of the handwheel interfaces at the Ethernet bus -> MD11352 $MN_HANDWHEEL_INPUT[< x - 1 >] = y
