PLC parameters
The below table contains all parameters which are relevant for the PLC configuration. The parameters
which can be set depend on the selected communication channel.
Parameter name
Meaning
Communication channel
Selection of the connection between PC and PLC.
•
See chapter 2.1, ”Connection to the PLC”.
Response time
Maximum time in [s] within which the PLC is expected to respond.
•
Unless the PLC responds within the selected time, it is likely that a
communication error has occurred and an error message will be
indicated.
•
Normally, the default settings need not be changed.
PLC address
1)
Address of the PLC connected to the PC.
•
When using an MPI/PROFIBUS connection, you only have to select the
MPI/PROFIBUS address.
•
When using an Ethernet connection, you have to select the MPI
address and the IP or H1 address.
CPU slot number
2)
PLC slot into which the CPU card is plugged.
•
Default: 2
Mounting rack number
2)
Mounting rack which includes the CPU card of the PLC.
•
Default: 0
PC-MPI address
1) 3)
MPI or PROFIBUS address of the PC
Baud rate
3)
MPI bus transmission rate between PC and PLC
Max. MPI address
3)
Highest device address on MPI bus
Only master
3)
Select this checkbox, if the PC is the only master on the bus. Otherwise,
the system might stop if a token is lost in case of a communication error.
Routing in MPI/TCP/H1
sub-networks
Selection of the sub-network type if the selected communication channel
allows routing in sub-systems.
•
For communication channels and PLCs which support the routing
function.
Sub-network ID
Identification of the sub-network.
Target MPI/TCP/H1 address
Address of the PLC in the sub-system.
DB number of the OPC list
1)
Number of the data block which is used for data exchange between PC
and PLC.
•
This number is detected by the scan function.
•
Unless the numbers of the enclosed Lenze blocks are changed, enter
”80” for DB80.
Maximum number of devices to be
found.
To save time, in particular, when scanning the PLC program for connected
devices at the server’s start, it is possible to enter the maximum drive
address to be checked.
•
If ”0” is selected, all drive addresses will be scanned (default).
Scan at Server Start of Comm.
The PROFIBUS addresses are automatically detected when the bus server
is started and need not be configured manually.
1)
This parameter is automatically set during automatic PLC scanning.
2)
When using sub-systems, this parameter refers to the PLC in the sub-system and not to the master PLC.
3)
This parameter is only valid for the ”COMx MPI” communication channel.
