The NC writes/reads the axis data to the corresponding I/O area of the PLC/DP master on
the basis of the I/O addresses entered in the following machine data and the message frame
type of the machine axis:
● MD13050 $MN_DRIVE_LOGIK_ADDRESS[ n ]
● MD13060 $MN_DRIVE_TELEGRAM_TYPE[n]
1. Machine axis: I/O address 4100
Message frame type 102
2. Machine axis: I/O address 4140
Message frame type 102
