The following table lists the system parameters for the function block:
|
Parameter (Data Type) |
Default Value |
Characteristics |
Description |
|---|---|---|---|
|
ARM_TRAP (Discrete with status) |
1 |
Access: Configurable, Tuning NVM: Restored on Restart |
When True (1), ARM_TRAP enables the first out trap mechanism. |
|
BCD (16-bit unsigned integer) |
0 |
NVM: Preserved on Download |
The binary coded decimal representation of the discrete inputs. |
|
FIRST_OUT (32-bit UInt w/Status) |
0 |
NVM: Preserved on Download |
The binary weighted output when one or more inputs is set after RESET_IN is set. |
|
IN_Dn (Discrete with status) |
0 |
Access: Tuning NVM: Restored on Restart |
The discrete input values and statuses. The number of inputs is an extensible parameter. |
|
OUT_D (Discrete with status) |
0 |
NVM: Preserved on Download |
The output value that represents the logical OR of the discrete inputs. |
|
OUT_INT (32-bit UInt w/Status) |
0 |
NVM: Preserved on Download |
The unsigned 32-bit binary weighted output value that represents the bit combination of the inputs. |
|
RESET_IN (Discrete with status) |
0 |
Access: Tuning (SLS 1508 and CSLS major revision 1) Operating (CSLS major revision 2 or higher) NVM: Preserved on Download |
When True (1), RESET_IN clears FIRST_OUT. The trap condition is not activated again until all inputs go False. The block sets RESET_IN back to zero at the end of each scan. |
