CAUTION!
As soon as the user program transfers the connection data via FB 55
IP_CONF, the CPU switches the CP briefly to STOP. The CP accepts the
system data (including IP address) and the new connection data and pro-
cesses it during startup (RUN).
8.2.13.2 FB 55 - IP_CONF
Depending on the size of the configuration DB, the data may be transferred to the CP in
several segments. This means that the FB must as long be called as the FB signals com-
plete transfer by setting the DONE bit to 1.
The Job is started with ACT = 1.
Parameters
Parameter Declaration Data type Memory block Description
ACT INPUT BOOL I, Q, M, D, L
n When the FB is called with ACT = 1, the DBxx
is transmitted to the CP.
n If the FB is called with ACT = 0, only the status
codes DONE, ERROR and STATUS are
updated.
LADDR INPUT WORD I, Q, M, D,
constant
Module base address
When the CP is configured by the hardware config-
uration, the module base address is displayed in
the configuration table. Enter this address here.
CONF_DB INPUT ANY I, Q, M, D The parameter points to the start address of the
configuration data area in a DB.
LEN INPUT INT I, Q, M, D,
constant
Length information in bytes for the configuration
data area.
DONE OUTPUT BOOL I, Q, M, D, L The parameter indicates whether the configuration
data areas was completely transferred. Remember
that it may be necessary to call the FB several
times depending on the size of the configuration
data area (in several cycles) until the DONE param-
eter is set to 1 to signal completion of the transfer.
ERROR OUTPUT BOOL I, Q, M, D, L Error code
