500000 baud
Parity: none, even, odd
Data bits: 5, 6, 7, 8
Stop bits: 1, 1.5, 2
Handshake: no handshake, hardware, software
The default settings in the programming system are printed in bold.
16.3.1 Parameter Maximum Waiting Time for Response
This parameter indicates the length of time that the operating terminal (master)
waits for the response from the PLC (slave).
Permitted values are in the range of 1 ms to 65535 ms.
The default value is 1000 ms.
16.3.2 Parameter Delay Until Connection Setup
This parameter specifies the time the operating terminal waits before initiating
communication.
Permitted values are in the range of 100 ms to 25500 ms
The default value is 5000 ms.
16.3.3 Additional Parameters
A network address is assigned to every variable by means of the slave number.
This assignment is carried out in the programming software via the variable list.
This address is used to exchange data between the operating terminal and con-
troller.
Enter the corresponding information into the additional parameters to establish an
assignment between the L.U.M.P. address and slave number. When using multi-
point connections (1:N), also enter the office numbers.
If the check box 1:N Communication is selected, the protocol also transfers the
office numbers.
The check box Access Authorization Control ensures that the operating terminal
is checked for an access authorization (whether it has or will receive this access
authorization) prior to every access to the controller. The access authorization con-
trol feature is only required if more than four devices access the memory of the
controller via the protocol.
