Name Inputs Outputs
10 EB of current phase 1 1
11 EB of current phase 2 1
12 EB of current phase 3 1
13 EB of current in neutral conductor
1
Number of bytes 14 2
The user has to change the pre-assignment in the circuit-breaker as follows:
Byte Name
(default allocation)
Data point
(default allocation)
Name
(allocation needed)
Data point
(allocation needed)
2 / 3 Current in phase 1 380 Current in phase 1 380
4 / 5 Current in phase 1 381 Current in phase 1 381
6 / 7 Current in phase 1 382 Current in phase 1 382
8 / 9 Max. current in phase
under highest load
374 Current in neutral conductor 375
If this adjustment isn't undertaken, the current in the neutral conductor is also shown in the
faceplate for current in the neutral conductor.
3.3.6 Addressing and module driver
The I/O addresses of 3VL must lie completely within the process image of the CPU. In the
CFC chart, the LADDR input is connected to the base address of the 3VL device.
Procedure:
Select input parameter → right mouse button → Interconnection to
address... → Entere.g. EW512
If 3VL is directly connected to the DP master system, the module driver connects block
outputs OMODE, QRACKF and QMODF to inputs MODE00, RACKF and MODF of the block
MOD_PAX0 and the module driver connects input DIAG_INF to output QDIAG_INF of
diagnostics block DIA_WLVL.
In the case of operation following a Y-Link DPV1, the module driver connects block inputs
MODE, RACKF and DIAG_INF to outputs OMODE, QRACKF and QDIAG_INF of
diagnostics block DIA_WLVL.
In the case of operation following a Y-link DPV0, the module driver connects block inputs
MODE and RACKF to outputs OMODE00 and QRACKF of diagnostics block PADP_L00.
The block input BASADR is parameterized with the logical base address of the 3VL device
by the module driver.
The block input BASADR_OUT is parameterized with the start address of the outputs of the
3VL device by the module driver.
The input DPA_LINK is parameterized with the connection mode of the 3VL device by the
module driver.
●
DPA_LINK = 0 → Directly connected to the DP master
● DPA_LINK = 1 → Connected following a DP/PA link
