FFFFFF
Enter the address of the memory location to be monitored by the variable
signaling function.
Note
This machine data is effective only if the signal number is set to 0 (see MD
5621).
Minimum:
Maximum:
0
FFFFFF
Enter the threshold for the memory location address entered in MD 5622:
PROG_SIGNAL_ADDRESS which is to be monitored by the variable signaling
function. In combination with MD 5624: PROG_SIGNAL_HYSTERESIS, this
defines the actual value to be checked by the monitoring function (see diagram
under MD 5620, Fig. 4-21).
Note
Depending on machine data MD 5620: PROG_SIGNAL_FLAGS, the numerical
value entered in MD 5624 is interpreted as an unsigned value (bit 2 = 0) or a
signed value (bit 2 = 1).
Minimum:
Maximum:
0
FFFFFF
Enter the hysteresis (tolerance band) for the memory location address entered
in MD 5622: PROG_SIGNAL_ADDRESS which is to be monitored by the vari-
able signaling function. In combination with MD 5623:
PROG_SIGNAL_THRESHOLD, this defines the actual value to be checked by
the monitoring function (see diagram under MD 5620, Fig. 4-21).
Note
Depending on MD 5620: PROG_SIGNAL_FLAGS, the numerical value entered
in MD 5624 is interpreted as an unsigned value (bit 2 = 0) or a signed value
(bit 2 = 1).
