CTUPDLVL - CTRIO Update Level
The CTRIO Update Level (CTUPDLVL) instruction is used to change the Level configuration of one of the CTRIO's Discrete Outputs (for description of that function see Discrete Output For Input Function under (2) Level (button) bullet). The CTUPDLVL instruction can be used with both the CTRIO and CTRIO2 module. After the level value is updated, the input transitions to a traditional Enable function, meaning that as long as the ladder logic input has power flow, the output will be enabled.
Changes made to CTRIO Preset tables using this instruction do not change any of the Preset tables that were configured in the Module Configuration for the CTRIO. They are temporary and are lost on a power-cycle of the CTRIO or if some other table is loaded in their place. The changes made by this instruction cannot be viewed in the Module Configuration.
Parameters:
Note: Use the F9 key or click the 'three dot box' at the right edge of the parameter field to open the Default Element Selection Tool (the Element Picker or the Element Browser) or use the Down-Arrow key (Auto-Complete) on any parameter field to see a complete list of the memory locations that are valid for that parameter of the instruction.
Discrete Output Device - selects which preconfigured CTRIO Discrete Output device to use. Before this instruction can select a Discrete Output device, a CTRIO Device must be configured with at least one of its output channels setup for Discrete output mode.
no devices available - indicates that there are no CTRIO Discrete Output devices that have been configured that can perform this instruction.
create module - will open the Create New Module Configuration dialog where a CTRIO Module can be created and then a CTRIO Discrete Output device can then be configured.
Discrete Output Structure - displays the name of the Discrete Output structure that will be used by this instruction. This structure was created when the CTRIO module configuration was read during the Module Configuration phase.
Output is - specifies the new Output state: ON or OFF.
When Level is - specifies the level comparison operator: Greater thanor Less than.
Scaled Level - specifies the new Level value. This can be any constant value of any readable numeric location.
Deadband (tenths of %) - specifies the new deadband value in tenths of a percent. This can be any integer constant value in the range of 0 to 1000 or any readable numeric location.
The On Success and On Error parameters specify what action to perform when this instruction completes. You do not have to use the same type of selection for both On Success and On Error.
If the Set Bit selection is used for either On Success or On Error, the specified BIT location will be SET OFF when the instruction is first enabled and will remain OFF until the instruction completes. Once complete, the appropriate Success or Error bit location ON. The specified Bit location is enabled with a SET (Latch) operation meaning that it will remain ON even if the input logic for the instruction goes OFF.
If the JMP to Stage selection is used for either On Success or On Error the target Stage must be in the same Program code-block as this instruction, you cannot specify a target Stage that exists in a different Program code-block. When the operation finishes, the target Stage will be enabled the same way as a standalone Jump to Stage (JMP) instruction would do it. The JMP to Stage option will only be available if this instruction is placed in a Program code-block.
On Success selects which of the following actions to perform if the operation is successful:
- Enable SET Bit then specify any writable bit location.
- Enable JMP to Stage then specify any
Stage number from S0 to S127 in the current Program code-block.
On Error selects which of
the following actions to perform if the operation is unsuccessful:
- Enable SET Bit then specify writable bit location.
- Enable JMP to Stage then specify any Stage number from S0 to S127 in the current Program code-block.
If either the On Success or On Error selections are set to JMP to Stage, Automatically create the SG box for any NEW stage number will be enabled which will automatically create any target stage that does not already exist.
- Below this rung will create the new target stage on a new rung following this instruction.
- At end of code-block will create the new target stage as the last rung of this Program.
Note: any time the On Error condition occurs, the CTRIO generates an Error Code that can be read in the <Module Name>.ErrorCode (Module Name is the name assigned to the CTRIO in the Module Configuration). The List of Error Code values (in decimal) follows:
Status Display:
The status display of the instruction shows Values: Scaled Level, Deadband (tenths of %), and Pulse Time (ms), and the Highlight: .OutputEnabled bit.
The red triangle in the upper left corner of the status display indicates this is a Fully Asynchronous instruction.
The gray triangle at the right end of the input leg indicates the input is edge-triggered, meaning this instruction will execute each time the input logic transitions from OFF to ON.
CTRIO Structure Field Care-Abouts:
The following is a list of the"dot" fields of the CTRIO structure that are programmatically used with the CTRIO Update Level (CTUPDLVL) instruction. To see a complete listing of all CTRIO structures and members, go to the Project Browser --> Configuration --> Memory --> I/O --> Specialty.
COLOR KEY
Blue: CTRIO Input
Maroon: CTRIO Output
Black: CTRIO Module
Silver: Not used for this instruction
Note: The red "x" is the digit 0, 1, 2, or 3.
NOTES:
(1)This structure member only available for CTRIO2 (not CTRIO). For CTRIO this remains zero.
