|
q_wAlrmId |
WORD |

|
Status Bit |
Description |
|---|---|
|
0 |
trolley/bridge/hoist is in the working area. |
|
1 |
trolley/bridge/hoist is between the Slow forward and Stop forward positions. |
|
2 |
trolley/bridge/hoist is beyond the Slow forward and Stop forward positions. |
|
3 |
trolley/bridge/hoist is between the Slow reverse and Stop reverse positions. |
|
4 |
trolley/bridge/hoist is beyond the Slow reverse and Stop reverse positions. |
|
5 |
Detection of active area and check of limit switch input combination is disabled. |
An alarm signal is generated in the cases of incorrect limit switch configuration or improper operation of a limit switch.
The function block detects any incorrect signalling of the position with respect to the movement, i.e. during movement, the signalling of any limit switch position located in the opposite direction of the movement generates an alarm.
When the FB is applied for 2 bridges/trolleys moving on the same rail and if the input i_xDisLsAlrm is set to TRUE the function block disables the plausibility check of the limit switch inputs which detects a wrong order of limit switch signals.
