7.6.5.2 Signal transmission from/to NC/PLC interface (FC26)
Description of functions
The FC 26 function "HPU_MCP (machine control panel signals of the handheld unit HT8"
transfers the HT 8 specific signals of the following functions between the HT 8 input/output
data area parameterized in the FB 1 function module (parameter: MCPxIn and MCPxOut)
and the NC/PLC interface:
● Operating modes
● INC machine function
● WCS or MCS coordinate system
● Axial traversing keys
● Axis selection
● Feed override
● Rapid traverse override
● Key switch information
Note
The FC 26 function is a part of the basic PLC program. The user (machine manufacturer)
is responsible for calling the function.
Parameter
Parameter Type Comment
BAGNo BYTE Upper Nibble
number of the MCP whose signals are to be transferred. 0 = 1. MCP, 1 =
2nd MCP
Lower Nibble
number of BAG in which the BAG-specific interface signals are to be
transferred. There is no processing of BAG-specific signals for BAG no. 0.
Value range
1st MCP: B#16#00 - B#16#0A
2nd MCP: B#16#10 - B#16#1A
ChanNo BYTE Number of the channel in which the channel-specific interface signals are
to be transferred. There is no processing of channel-specific signals for
Channel no. 0.
Range of values:
B#16#00 - B#16#0A
