The serial communication happens via the deployment of handling blocks
in the PLC user application. These handling blocks may be downloaded
from www.vipa.com.
For the internal communication the VIPA FCs are to be used. Here the data
is transferred with a maximum block size of 12Byte.
Depending on the protocol the following handling blocks are used:
ASCII STX
3964
RK512 Modbus FC Name
x x x FC0 SEND_ASCII_STX_3964
x x x FC1 RECEIVE_ASCII_3964
x FC2 FETCH_RK512
x FC3 SEND_RK512
x FC4 S/R_ALL_RK512
x x x x FC8 STEUERBIT
x x x FC9 SYNCHRON_RESET
x FC11 ASCII_FRAGMENT
Note!
A communication with SEND and RECEIVE blocks is only possible if the
parameter ANL of the SYNCHRON block has been set in the start-up-OB
before.
