Data mapping to the DP network:
X20~X57 4 bytes output
Y20~Y57 4 bytes input
ELC-Pxxxxxxx
ELC-COPBDP
From DP Master
To DP Master
The ELC-COPBDP provides a fixed 4bytes of input data and 4bytes of output data that are
exchanged with a Profibus master.
The 4bytes of input data are transmitted from the ELC-COPBDP module to the Profibus
Master. This data is automatically taken from the output relays (Y) assigned to the extension
unit. For example if the ELC-COPBDP is the first extension unit, the 4 bytes of data come
from Y20-Y57 of the ELC controller..
The 4bytes output data are transmitted from the Profibus Master to the ELC-COPBDP
module. This data is automatically placed in the input points (X) assigned to the extension
unit. For example if the ELC-COPBDP is the first extension unit, the 4 bytes of output data is
placed in X20-X57 of the ELC controller.

Example ladder program :
M1000
MOV K4X20 D10
MOV
MOV
MOV
K4X40
D20
D21 K4Y40
K4Y20
D11
This program example copies the 4 bytes data from X20-X57 that are transmitted by the
Profibus-DP master to D10 and D11 registers in the ELC controller. It also copies ELC
register D20 and D21 to Y20-Y57. These 4 bytes data are sent to the Profibus-DP master.
