"Replace module without PG" box
● Save configuration data on the CPU:
If you enable this option, the system data blocks (SDBs) of the TIM module are stored on
the CPU. If the TIM module fails, the defective TIM can be replaced by a TIM of the same
type without leading to download the SDBs to the TIM using a PG. The Tim module
receives its SDBs during startup from its local CPU.
If the TIM is configured as a stand-alone without a CPU in the rack, this function is not
available.
Note
If there is no C-PLUG inserted in a TIM 4R-IE DNP3, the configuration data is stored in
flash memory. If there is a C-PLUG inserted in the TIM 4R-IE DNP3, the configuration
data is stored automatically on the C-PLUG when it is downloaded to the TIM. If you
replace the module, you can insert the C-PLUG with the configuration data in the new
module.
"Security settings for Ethernet interface" box
● IP address may be read using DCP
If the option is enabled, the TIM replies to read queries for the IP address using the DCP
protocol (Discovery and Basic Configuration Protocol). The address of the TIM cannot be
modified using DCP.
DCP is used by a PG with the aid of the Primary Setup Tool (PST) or the addressing
function of the SIMATIC Manager.
