Parameter Declaration Data type Memory block Description
LADDR INPUT WORD I, Q, M, D, L,
constant
Configured start address of the output buffer of
the module to which the data must be written.
RECORD INPUT ANY I, Q, M, D, L Source area for the user data that will be written.
The length must be exactly the same as the
length that was configured for the selected
module. Only data type BYTE is permitted.
RET_VAL OUTPUT INT I, Q, M, D, L The return value contains an error code if an
error is detected when the function is being pro-
cessed.
Value Description
0000h No error has occurred.
8090h You have not configured a module for the logical base address that you have specified, or you have
ignored the restrictions that apply to the length of the consistent data.
8092h The ANY-reference contains a type that is not equal to BYTE.
8093h No DP-module to which consistent data can be written exists at the logical address that was specified
under LADDR.
80A1h The selected module has failed.
80B0h Slave failure at the external DP-interface.
80B1h The length of the specified source area is not equal to the configured user data length.
80B2h External DP-interface system error
80B3h External DP-interface system error
80C1h The data of the write command that was previously issued to the module has not yet been processed.
80C2h External DP-interface system error
80Fxh External DP-interface system error
85xyh External DP-interface system error
808xh External DP-interface system error
14.1.14 SFC 17 - ALARM_SQ and SFC 18 - ALARM_S
Every call to the SFC 17 ALARM_SQ and the SFC 18 ALARM_S generates a message
that can have an associated value. This message is sent to all stations that have regis-
tered for this purpose. The call to the SFC 17 and the SFC 18 can only be issued if the
value of signal SIG triggering the message was inverted with respect to the previous call.
If this is not true output parameter RET_VAL will contain the respective information and
the message will not be sent. Input SIG must be set to "1" when the call to the SFC 17
and SFC 18 is issued for the first time, else the message will not be sent and RET_VAL
will return an error code.
RET_VAL (Return value)
