Type of control
The control type must be specied in the Analog Control Byte m+1 (bit 0), so that the 16 bit input
and output values from and for the analog module are correctly interpreted by the control. In the
SINUMERIK 840D sl control, the value "0" must be entered here.
Note
The control type must be set prior to the operating mode so that the rst set of user data is not
misinterpreted. In addition to this, the Analog Control Byte m+0 / m+1 must only be accessed
byte by byte.
Assigning parameters to the analog inputs
The analog inputs (AI) can be operated in the following operating modes:
Operating mode 1st channel Bit 1 Bit 0
No operating mode 0 0
Voltage measurement 0 1
Current measurement 1 0
Temperature measurement (Pt100) 1 1
Operating mode 2nd channel Bit 3 Bit 2
No operating mode 0 0
Voltage measurement 0 1
Current measurement 1 0
Temperature measurement (Pt100) 1 1
Assigning parameters to the analog outputs
The analog outputs (AO) can be operated in the following operating modes:
Operating mode 3rd channel Bit 5 Bit 4
No operating mode 0 0
Voltage output 0 1
Current output 1 0
Impermissible operating mode 1 1
Operating mode 4th channel Bit 7 Bit 6
No operating mode 0 0
Voltage output 0 1
Current output 1 0
Impermissible operating mode 1 1
