DCP flashing

This function is used to check the correct assignment to a module and its interfaces. This
function is supported by a CU310-2 PN and a CU320-2 DP/PN with inserted CBE20. The
function can also be used without CBE20 in a CU320-2 PN. DCP flashing
1. In HW Config or the STEP 7 Manager, select the menu item "Target system > Ethernet >
Edit Ethernet node".
The "Edit Ethernet Node" dialog box opens.
2. Click the "Browse" button.
The "Browse Network" dialog box opens and displays the connected nodes.
3. Select the CU310-2 PN or the CU320-2 DP with inserted CBE20 as node.
The "DCP flashing" function is then activated via the "Flash" button.
The DCP flashing will be effective on the RDY LED (READY LED 2 Hz, green/orange or
red/orange) on the CU310-2 PN/CU320-2 DP.
The LED will continue to flash as long as the dialog is open. When the dialog box is closed,
the LED automatically goes dark. The function is available as of STEP 7 V5.3 SP1 via
Ethernet or via STARTER.
11.3.1.5

Data transfer

Properties
The PROFINET interface on a drive unit supports the simultaneous operation of:
● IRT – Isochronous Real Time Ethernet
● RT – Real Time Ethernet
● Standard Ethernet services (TCP/IP, LLDP, UDP and DCP)
PROFIdrive telegram for cyclic data transmission, acyclic services
PROFIdrive telegrams are available for implementing cyclic communication via PROFINET
IO (see chapter "Communication according to PROFIdrive", Cyclic communication
(Page 738)).
Telegrams to send and receive process data are available for each drive object of a drive
unit with cyclic process data exchange.
In addition to cyclic data transfer, acyclic services can also be used for parameterizing and
configuring the drive unit. These acyclic services can be utilized by the IO supervisor or IO
controller.
Sequence of drive objects in the telegram
On the drive side, the sequence of drive objects in the telegram is displayed via a list in
p0978[0...24] where it can also be changed.
