MD30210

The number of the module within a bus segment (MD30210 $MA_ENC_SEGMENT_NR[n])

through which the encoder is addressed must be entered in the MD.

For axes on PROFIBUS/PROFINET, the number of the drive assigned via MD13050

$MN_DRIVE_LOGIC_ADDRESS must be entered here (MD30220 $MA_ENC_MODULE_NR=n

consequently points to MD13050 $MN_DRIVE_LOGIC_ADDRESS[n]).

The index[n] of the machine data has the following coding:

[Encoder no.]: 0 or 1

Related to:

MD30110 $MA_CTRLOUT_MODULE_NR[n]

(setpoint assignment: drive number/module number)

For PROFIdrive only:

Logical I/O addresses of the PROFIdrive drives on the PROFIBUS/PROFINET. An

address is assigned to a drive.

This MD is the link to the description of the PROFIBUS/PROFINET configuration

in SDB.

The MD value is the address index of the logical I/O drive address assigned

with HW-Config (SIMATIC Manager S7).

Example:

DRIVE_LOGIC_ADDRESS[1] = 272 (The start address 272 is assigned to drive 1.)

The SDB defines the logical I/O address of the drives on the PROFIBUS/PROFINET.

An address is assigned to a drive or to a slave.

The address index is used for actual-value and setpoint-value assignment

(MD30220 $MA_ENC_MODULE_NR[n], MD30110 $MA_CTRLOUT_MODULE_NR[n]).

Note:

The same drive (I/O address) must be assigned to the MD30220

$MA_ENC_MODULE_NR[0] and MD30110 $MA_CTRLOUT_MODULE_NR[0]

of a machine axis.

Each drive or slave must be assigned to a single logical address index.

The index [n] of the machine data has the following coding: [Drive index]:

Drive 1 -->n-=0

Drive 2 -->n-=1,
