Lenze C520 - Address assignment

conguraon is based on the designator (STRING). If a slave has to be contained in a
conguraon (Mandatory Slave), it is marked by an 'X' in the following sample table.
Address 1001 1002 1003
Inverter i700 9400 CiA 9400 AS
Conguraon 1: All inverters are
congured.
X X X
Conguraon 2: The 1st and 2nd
inverters are congured.
X X
Conguraon 3: The 1st and 3rd
inverters are congured.
X X
The conguraon le does not necessarily have to be available.
Precondions:
•
Manual address assignment via the L_ETC_MMCAssignAddress funcon block
•
Operaon of the EtherCAT master in the "RUN_WITHOUT_CHECK" mode
Dependencies between conguraon les and services
Depending on the selected service, informaon from the machine conguraon le "mmc-0-
conf.csv" and the le for further idencaon features of the slaves "mmc-0-ident.csv" is
required. If the les are not available or if there is a "Parsing Error", one of the following error
messages results when a service is acvated: "CONFIG_FILE_ERROR" or "IDENT_FILE_ERROR".
8.1.11.4 Address assignment
Before the EtherCAT master in the modular machine conguraon can switch to the operang
mode "RUN_[...]" each EtherCAT slave has to be assigned a "Second Staon Address" (alias
address). For this purpose, the funcon block L_ETC_MMCController oers the services
"ADDR_ASSIGNMENT_EXTERNALLY" and "ADDR_ASSIGNMENT_CONFIG_SLAVEORDER".
For all address assignment services, the EtherCAT master reads out the relevant informaon
from the slaves to create a temporary conguraon and sets the slaves to the "Pre-
Operaonal" state. For this purpose, the master assigns the addresses for the slaves
connected in ascending order starng with "1". Thus, the address is idencal to the posion of
the slave in the network.
ADDR_ASSIGNMENT_EXTERNALLY service
For this service, the "Second Staon Address" (alias address) can be assigned manually from
the PLC applicaon (e.g. via a visualizaon). This service provides the CoE funcon blocks.
Parameters such as vendor ID, product code, revision, and serial number can be read out from
the slave or parameters can be described for "Opcal Tracking". If a slave has been clearly
idened and assigned, the L_ETC_MMCAssignAddress funcon block can be used to write
the address to the slave.
ADDR_ASSIGNMENT_CONFIG_SLAVEORDER service
For this service, the "Second Staon Address" (alias address) is automacally assigned. For
this purpose, a conguraon has to be specied, e.g. via the machine conguraon le
"mmc-0-conf.csv". Based on the conguraon, the EtherCAT master receives informaon on
which slaves are to be expected at the bus. If the slaves are actually available, the "Second
Staon Address" is wrien to the slaves. Here, in addion to the vendor ID and product code,
the current ascending order of the slaves at the bus is important.
