Machine data which correspond to this machine data are as follows:
• Signal number variable message function (MD 1621)
• Address variable message function (MD 1622)
• Threshold variable message function (MD 1623)
• Hysteresis variable message function (MD 1624)
• Pickup delay variable message function (MD 1625)
• Delayed dropout variable message function (MD 1626)
Note:
Changes to inputs in machine data MD 1621 to MD 1624 while the monitoring function is
already active (MD 1620 - bit 0 = 1) do not automatically result in re-initialization, i.e. reset to
zero, of message bit 5. If a bit reset is required, the monitoring function must be deactivated
and then re-activated by means of MD 1620, bit 0, after the machine data has been altered.
