The transfer parameters Q1 to E3 are strings and must therefore be entered in
quotation marks (" "). The following system variables are permissible as input
quantities:
$A_MARKERSI[ ]
$A_INSE[ ]
$A_INSI[ ]
$A_OUTSE[ ]
$A_OUTSI[ ]
E2 and E3 are optional. If these parameters are not entered, the relevant inputs
are set to "1" (static signal).
SIRELOUT: This language command assigns the input quantities A0, A1, A2 and
A3 to the safety relay x (x = 1..4). The return value "status" contains the number of
the first incorrect parameter; a value of 0 indicates that the parameter assignment
is correct.
Syntax:
The transfer parameters A0 to A3 are strings and must therefore be entered in
quotation marks (" "). The following system variables are permissible as output
quantities:
$A_MARKERSI[ ]
$A_OUTSE[ ]
$A_OUTSI[ ]
$A_PLCSIOUT[ ]
A1 to A3 are optional. If these parameters are not specified, then the correspond-
ing outputs are not supplied. However, if A1 is specified, the initialization value for
timer 1 (TI1) must also be parameterized via SIRELTIME. The same applies for A2
and timer 2 (TI2) and A3 and timer 3 (T!3).
SIRELTIME: This language command assigns the times -- for the timers required --
to safety relay x (x = 1..4). These include the timer limit value TM1 and the timer
initialization values TI1, TI2 and TI3. The return value contains the number of the
first incorrect parameter; a value of 0 indicates that the parameter assignment is
correct.
Syntax:
Transfer parameters TM1 to TI3 are REAL numbers (times in seconds). TI1 to TI3
are optional. If these parameters are not specified, the corresponding outputs A1
to A3 are not supplied. However, if TI1 is specified, output A1 must also be para-
meterized via SIRELOUT. The same applies for TI2 and A2 and TI3 and A3.
